Back in 2018 I repowered my 1949 Chevy 3100 with a 1954 235 engine. In this VLog I cover some of the info I aquired in determining what 6 cylinder engine to repower my truck with and several other options that were and are available for a 6 cylinder repower for this series of GM trucks. This by no means includes all the options but I touch on many that I learned about in my quest.

I wonder what modifications are needed to the radiator to drop a 292 into a 52 belair convertible. And any other drive train modifications needed. I'm thinking of resto moding it for daily and interstate driving. I want to drive it long distance to car shows. The 261 with a 4 barrel, 350 tranny, 350 rear was my original plan. Ideally, i want to squeeze out mid 250 horses without blowing it or making it sound too rumbly. This video had the best suggestions and insights into these 6 bangers i have seen yet. You master mechanics are invaluable to a novice like me. Great workl! I must follow and binge watch your channel.

@Volfandt 8 месяцев назад

The 292 is longer than the 216/235/261 Stovebolt engines by approx 3", I would guess the radiator would have to be moved forward and whatever mods necissary to do such. That said I'm not very familure with the Stovebolt cars of that era and they "may" have ample room for a 292. You can get decent power out of a 235/261 and with a an Overdrive trans & a higher rear gear mod you should be interstate capable. Good luck in your adventures and thanks for watching Dennis.

I did the T5 overdrive swap in my '53 Chevy pickup, '86 S10 trans was the best desired ratios for lower gears and the OD ratio. Junkyard wanted $700 for the trans, professionally rebuilt with 6 month warranty was a no brainer at $1000. For the rear axle you can use a '55 to '61 or maybe '62 third member , paid $125 for it, with 3.90 ratio that drops right in the original housing with the original axles. Then you must weld the housing at the pivot point, after setting the pinion angle, to prevent it from moving. And of course you need a driveshaft. Even with the 216 engine 65 or 70 MPH is no problem, best upgrade yet. Too bad the 216 has developed a knock so I may put a 235 in it. By the way, your truck sounds really good!

It cost more for us to upgrade to the 261 from the 216 in our 50 Chevy 3100 we also upgraded to a four speed Saginaw transmission and a twelve bolt GM rear end. The cheaper upgrade is a small block Chevy. Thank You for posting on RU-vid Hello from La Pine Oregon

Was not aware of the engine mounting variations on these early GM vehicles. I put a 302 GMC in a '50 Chevy car, and don't remember having to change much of anything.

@Volfandt 9 дней назад

Theres quite a bit of difference in the frontends between the Chevy cars & trucks. Sounds like theres more room in the car engine bay. Thanks for watching.

@michaelihnatko7458 3 года назад

@20:31 you mention drilling steam holes when swapping the 848 head onto a 261 for higher compression that reminds me of the days when people were swapping bigger valve hp 350 heads onto the 400 Chevy small block and if the steam holes were not drilled into 350 heads over heating problems would happen. I figure I might help someone out with that info.

@willymccoy3427 11 месяцев назад

My Dad's shop wrecker for years was a 47 Chevy big truck that he swapped a GMC 302 in. He said he had to do some work the radiator and front engine mounts to get it tor work, but he used that truck for years. After he passed, it ended up sitting the shop yard and eventually the block froze and cracked. Last I heard of it, my sister asked me if I wanted it, but I had no way to get it halfway across the country from coastal NC to West TN. No idea on it beyond that point 15 or so years ago.

Consider the early Truck Hydramatic 4-speed transmission as an upgrade, along with the T-85 and/or T-89 Overdrive. Not necessary to go ape shit with modern tech and treat the old truck as totally obsolete. You young guys feel the need to reinvent the wheel and feed the scrap metal market.

Grandpas 55 first series had the rear end regeared for the highher speed and he took a 4 speed out of Chevy Vega (bolted right to the stock Bel housing) truck would cruise along just fine at 70mph like that though it didn't like getting over 75. Later he dropped a 350 in it and Borg Warner t10 truck hauls ass now

After watching I had to run out to my garage and check to see if I had a “848” head! I am sure my wife heard me yeah “o yeah” in the house lol! I had no idea that existed! When you changed the cam do you think that made a lot of performance difference? I am considering doing the dual weber carbs and dual exhaust also. Great videos and a ton of info thanks and talk to ya soon!

@Volfandt 3 года назад

Congrats on your 848 head, you have the highest compression head Chevy made for these Stovebolt engines. Since I went from a 216 to the 235 with the 264 cam, dual carbs & dual exhaust I definitely felt the increase in power. The engine pulls hard all the way to 4k rpm. The 216 died out around 3200 rpm. Although I ran the single carb at break in and run stand tuning, I never ran a single carb 235 in the truck so I don't have a seat of the pants comparison. I do some highway & back road cruising in this vlog: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-d_2ba9omBas.html You can see how well it cruises at 60 mph as well as lower. I can bury the speedo at 80 and it still pulls, I always shut down for fear of permanently damaging the speedo as well as not want to run it above 4K rpm unnecessarily. I definitely like the cam, dual carbs & dual exhaust but it's not a cheap upgrade and may not give you the ROI you may expect. If your stock 235 runs as well as mine at 60 you may not need it. Course, it's bling and always brings ahhs. Thanks for watching.

@johnpublic5169 Год назад

No mention of going way more modern with an LL8 Vortec 4200? What about a B model Cummins 4cyl? 3.9 liters just like a 235. External dimensions nearly identical. Only weighs about 200 pounds more. Apologies if you did touch on these. I only made it to 8:36 of the video. Too long winded and could use some editing to trim that time down. My truck is a little bigger. A GMC 355-24. The 248 was gone before I bought it. Cummins all the way, unless I get stupid and put a 4-53 Detroit in it, or a 3-71 Detroit like the 52-53 GMC 450 & 470 series trucks had.

@decosse01 Год назад

This is great compilationof facts! Thank you. The driveline options are more confusing to me than the engines however! If I have already made the investment in a 3.55 rear end, is the only automatic that retains the Torque Tube the early 50's car Transmission? Otherwise, you need the transmission, open drive prop and a rear end? Is that right?

@Volfandt Год назад

To my knowledge that is yes. It gets complicated when dealing with the Powerglide automatic as the early ones were cast iron & torque tube then they changed it to aluminium & open driveshaft. Good luck & thanks for watching.

@a075923 Год назад

Question on the 53 235's. My understanding on cars the stick shift cars in 53 still had the slasher and the powerglide cars had the full pressure. I had a 53 stick with the splasher in a 210 car.

@Volfandt Год назад

Hey Mike, your research is spot on. Unless someone did an engine swap the 235 in that 53 210 is more than likely a babbitt rod (or commonly called a splasher) engine since it's coupled to a straight stick tranny. Good luck

@loboheeler 10 дней назад

Not sure about the '53 trucks, but correct that the cars used a 216 splasher for manual trans, and a full pressure oiled 235 for auto trans. The 216 splasher was gone starting in '54. Was not aware the '53 235 auto trans had hydraulic lifters. I guess they thought an auto trans car should be quieter. The solid tappet Chevy 6 engines could be noisy, and valves were often set running.

@LedianCardoso 3 года назад

Quick question, do you know how much more horsepower you get when you add a dual carburetor set to a 235?

@Volfandt 3 года назад

Just adding dual carbs won't do much. Adding dual exhaust with dual carbs will give a slight increase. To get a noticeable increase you'll need to upgrade the cam, carbs & exhaust. Dual carbs DO increase the wow factor tho. Good luck.

@LedianCardoso 3 года назад

Thank you for your response but yeah when I said dual carb I meant also dual exhaust, I'm guessing you you are talking about changing the cam you mean to a 235 corvette cam so it would be just all that work for only 10 horsepowers?

@Volfandt 3 года назад

@@LedianCardoso Rejetting your current carb to a slightly larger main jet will improve your performance some. I discovered I could get better off the line performance by going with different springs on my distributors flyweights. Course I 'm running an after market distributor but it may be possible to order the spring kit from Pertronix and try it. If you're looking for interstate cruising get the 3.55:1 ring and pinion rear gears and you'll definitely notice higher speed cruising. It won't be as quick off the line but these old trucks aren't drag racers anyways... The stock cams in these old Stovebolt engines are designed for low rpm high torque output. If you want to wake up the engine and run where it makes the HP only a new cam designed for this will do it. I really like my dual carbs & exhaust and will never talk anyone away from this conversion. Good luck

@avmagic5610 Месяц назад

I have a 51 chevy truck. I can get a chevy 250 with turbo 350. Can the turbo 350 fit without cutting floor up?

@Volfandt Месяц назад

Unfortunately the bellhousing of the TH350, TH400 and newer automatics sticks out too much which means the firewall has to be cutout/trimmed for them to fit. You'll also need to change over to an open driveshaft since theres no adaptor to bolt the torque tube to the tranny and this also entails changing the rearend out for the open driveshaft. The 250 engine is around 2"-3" longer than the 216/235/261 engines that came in the old Stovebolt trucks and they bolt up differently. And since they are longer you'll have to modify the radiator mounting to push it forward so it'll clear the longer engine. It can be done but it takes alot of modification. It's not a drop-in upgrade. It's like the proverbial snowball rolling down hill...

i have a 1950 chevrolet 3100 truck with a 235 engine. have problem with no oil getting to top of rockers. checked all lines they are clear. removed oil pan test oil pump working but noticed oil going to oil pan looked at the oil distributor valve looks ok. only get oil to top when i plug off the oil distributor valve and the pressure gauge port. then i get oil to main bearings and to the rockers what could be wrong , any information would be helpful, thanks.

@Volfandt Год назад

Hey Eldin, I noticed you mention an oil distributor. They only came on the 216 engine. A few questions to verify the engine. 1) does the side push rod cover pan extend all the way up to the valve cover and the plugs install through it into the head? 2) Did the oil pan have 6 troughs that would have been right under the rods that would have had dippers on the end caps? If yes to both questions you have a 216 engine. Since you do get oil to the mains and up to the rockers when you block off the oil distributor and oil gauge port it sounds like you're not getting enough oil pressure. The way the oil distributor valve works is it limits oil pressure to the rockers which keeps the oil pressure high so the mains and cam bearings get lubed as soon as the engine starts and once oil pressure raises enough (I'm gonna swag it needs to be a minimum of 7-10 psi) the valve then allows oil to flow to the rockers. The mains and cam bearings are the priority and get all the oil until it reaches a set point. So it would appear either the valve is bad or the oil pump is too weak and doesn't pump up enough pressure. Theres rebuild kits for the valve and new oil pumps available. When the engine is running what is your oil pressure? My email is: volfandt1@yahoo.com

@eldinpeterson3760 Год назад

@@Volfandt yes to the both questions . i removed the oil pump and put a test gauge on it i get 100 PSI when full open turning with a drill at med speed then when i close the valve i get 70 PSI when the check valve goes off. i only get oil to the mains when i block off the distributor valve completely with a plate. other wise the oil just go to the oil pan. even when i turn drill fast to get 100 PSI i still get oil going to bottom. where would i get a distributor valve to replace this one. as i am in canada and can not find any kits to repair this valve. thank you for defining the engine. thank you for the help and all information .

@@eldinpeterson3760 Hey Eldin, My research shows that the relief valve is set to relieve at around 70 psi so it would appear your pump is OK. I found this 49 Chevy bulletin detailing the Oil Distributor and I suggest you pull yours, make sure the spring operates properly & isn't sticking, clean it up and all the oil passages you can reach and put it back together with those gaskets I linked to in a previous reply.
