This channel primarily contains content focused on the Long Island Mopars car club which is based in Long Island, New York. From time-to-time I will include other transportation-related content to celebrate how mobility has transformed our lives. Find the club on Facebook @Long Island Mopars.
@@LongIslandMopars I'm not a Mopar fan really but I do have my general Lee I still have the 426 Hemi I want to give you and today in a trade I picked up a Hemi cuda that someone put a 572 Merlin engine in
I have a pretty complete draw-thru turbo pontiac 301 setup. People just see the power #'s and say why try. Given the 1st gen catalytic converters were a big metal potato plugging the exhaust....and using a 'test pipe' and dumping the cat really made the poorly designed 301 show signs of life, even in such a heavy car. Anyway, thought it might be fun on a 273 2bbl longblock, bit hotter cam, hv oil pump, hp valvesprings. Need to fab a 'pyramid' and diffuser for the turbo to dump into that bolts were the 4bbl would be. One of the iron 273 4bbl intakes has a near 3/4" tapped hole right behind the carb pad, between runners 7 & 8. It's not drilled all the way thru the intake manifold. Thought it might make a good spot to dump the used turbo oil. I always run upper windage trays in the valley, hope the hot & aerated oil will hit it, lose some foam & dump some heat into the valley walls for the coolant to take away. Have some fun.
@@dantupper1784 That's very cool. I actually thought about a low pressure turbo set-up awhile ago. I am 8.5:1 compression with a mild Isky E-4 cam. The whole engine was rebuilt 12 years ago. 0.030 over with flat top pistons, factory forged crank and stock rods. I shelved doing the turbo as if like to keep the under hood appearance stock. Coronets with 273s never got the 4bbl option; that was the Commando engine only available in a Dart. What I should have done is gone with the high compression domed pistons that my engine builder talked me out of. He played it safe and the result is a great running engine without enough spunk. 😎
@@LongIslandMopars Yup- for years a friend and I have joked that the line from 'Hitchhikers Guide to the Galaxy' line about Earth as 'Mostly Harmless' applied to most 273's. All I hope for is near 250HP, which I think is in the realm of doable. Anything more would be a big surprise to just about everybody. Have a couple of the older, smaller cornelius kegs for the syrup used in the smaller 'countertop' soda fountains. The 'turbo buick 215' used a boost pressurized container full of water/methanol (20/20 windshield wash) that was squirted into the air above the carb during boost. Both Allied and Axis aircraft used a similar system in WW2- old tech. So you can see where I was going the the 'mini' cornelius keg. Just tap WW2 tech. Was going to add some kind of fliud level.sensor(s). Thought about using 4 of the window wash tank level sensors out of 18 wheeler window wash tanks, or a fuel level sender for boat tanks & fuel cells. Dunno. Want bright red No-Go light on at 1/4 tank and below. Cornelius kegs of all sizes are sometimes available at home brewing supply stores near me. Been kicking this idea around for a bit, and a 'Turbo 273' could be fun.
Ha, the old tires actually wound up on the Coronet a year later when I brought it home after Dad had passed. The kids across the street were playing basketball in the driveway. 🤬
@@ableline2000 That's what I was discussing this morning with a colleague that has a Road Runner. Going to get a proper spacer and jet/metering rod kit if one exists.
@@LongIslandMopars ty for the information, these must be the long option,I know he didn't like it always complaining about timing the carbs and the sluggish throttle,
@@Latemodellisa Yep, I know what his frustrations must have been. Long rams were good for high rpm running; short rams were better for off the line performance. Getting those carbs in sync took some doing and heaven forbid you had to remove the valves covers to adjust the valves. They were awesome to look at, though, and sounded amazing at WOT.
@@A2ZREY This one will be tough. The intake is a factory 273 Commando part with small throttle bores. The carb throttle plates are much bigger. I'll be weighing a spacer vs hogging out the throttle bores.
I THINK THAT CARB MAY BE A 650 CFM, I FOR SURE WOULD RUN A 750 CFM CARTER ON A 273 CUBIC INCH LA ENGINE. CHRYSLER PUT 800 CFM TQ'S ON 318 TRUCK ENGINES. I GUESS IF ONE DIDN'T KNOW HOW TO TUNE A CARB IT MIGHT BE A PROBLEM!
@@LongIslandMopars Spacers often add HP so that might work out quite well, but you'll still want to match the opening in the intake to match the spacer. I have a 650 competition on my 340 in my cj5, I run the smaller carb in the jeep because it works better at lower rpms wheeling thru the woods and trails at slow speed especially on steep grades. I ran the stock 800 cfm TQ when it was in street driven vehicles. Only been running it for 34 years, two trucks, two ram chargers. You know what people say, those damn Chrysler engines just aren't reliable. LOL
For this small engine, if the manifold would accept it; I would prefer a smaller 'spread bore' type (Holley Quadra jet style) for off the line performance and throttle response. Over carbueration is common mistake for novices. The 780 was too much for for my street 327, but the Holley 650 spread bore was perfect for humiliating big block 440s on the street.
@@neps4th I know. This carb was free. Ideally I need a 500cfm AFB for the small displacement engine. If I attempt to use this thing, I will document it on the channel.
