NITROUS 496 BBC-CUBES & CHEMISTRY!! 

WE'VE SEEN PLENTY GET HURT THAT WAY

I've have one also, got it off eBay last year. I think I'm going to try to build a Rat Rod around it, just to be different. Mine is for a Rec port BBC.

That is one sexy as fuck manifold. Not seen it before, but it ticks all the right boxes. Would prefer black over red, but is it normal for a bloke to get so excited over a manifold?

LunarOutlaw’s Garage do you have a link to that video I can't seem to find it.

Dodgy Brothers Engineering I had to go back to the videos ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gODDOrRKVEs.html

Dodgy Brothers Engineering The episode name was who wins eight stack ram versus xram

Thnx-I love what I do

@@richardholdener1727 best way to live your life, love doing what you're doing..

What cam

Jfb 1990 there’s tons of tricks to pull extra hp out of a motor

Yes, me too, i would Like tips for building the power he makes without breaking the engine.

What cam

@@infamousnova Bullet custom cam, 4-7 swap, lifts are around 805 but I’d have to check the cam card to be exact.

@@wheels2199 Hydraulic roller or Solid

@@infamousnova Solid roller

@@wheels2199 thats sweet, I'd def like to know the duration @ .050

Too large of a head can make a very lazy port and engine on a street engine.

Scott Worelds never seen it proved on a dyno. Never have I seen someone make a pull on a big flow head that lost bottom end put a smaller cam in to see if the power comes back but stays better up top.

Going to test this theory with my nephew - we have a '97 7.5l(460) BBF on the engine stand that's getting swapped into his Mustang next winter, and we're going to throw a set of Kaase's new bad mofo SR-71 heads on the stock short block(fly cut the pistons if necessary) for the first season with the big block before we build it next winter(or find a good deal on a used race short block w/ an aftermarket block - aluminum would certainly be NICE)

A few years ago, car craft did a test with ported Ls1 heads vs factory ls3 heads. Same cam, truck, camaro and ls2 intake on ls1. Truck and ls3 intake on ls3. The Ls3 was about 20hp up at the top end but more than 20ft lbs down at 3000 rpm and didn't pull ahead till 5k. For the strip, their computer simulated numbers using ls2 vs ls3 intake were within a tenth and 1mph, the ls1 ahead but around town the with the higher torque farther down, the author thought it wouldn't even be close. If you were to put these heads in this test on a 427, they would leave a ton on the table compared to something like a set of edebrock 454-O heads on a street driven engine. The torque difference at 3000rpm would be closer to 40 ft lbs, the camshaft doesn't have the lift to make use of the high flow these heads offer.

On the dyno from tests I've seen on a BBC too much head didn't hurt power, but would it be lazy on the street? Hard to tell that on a dyno. Great call Brian, would like to see a big head with a small-ish cam.

Never

@@richardholdener1727 You are CORRECT Call your own shots.

Why not 2020?

blazer slayer 88, BRINGO! 👍🏻

@@fascistpedant758 to late to get in the race

I keep testing them

yep

Not sure this comment applies to the BBC video

You cant read a graph? Everything you want is right there! Hit pause, and figure it out for yourself.

that is a hard motor to find and not much support

Spaghetti rods fold under stock power

Yessss we needs details

I believe he said 10 to 1 running it on 91 octane. Not sure about the rest.

show me when you run WOT at idle

that comes on the 540

@@richardholdener1727 I'd love to see it on a 468 at 7200 RPM Peak

There would be better choices-I just like it as an all-around when running NA and boosted and nitrous

@@richardholdener1727 I'm all ears, have this engine going together now, but no cam yet. Open to solid or hydraulic roller. 3000 stall, 68 Chevelle.

.007 per 1 inch of bore

coming-its all coming

try it, I know you think its written in stone-its not

@@richardholdener1727 been there, done that

we run 90 degree with long wires under our headers, but some run them on top

I tested EVERY Oval and EVERY Rec port BBC head a few years back-I have all that data.

Do we have a link somewhere?

@@richardholdener1727 do you have a link to the data from testing those heads or title to search for the video? I am building a 427 tall deck for my ‘81 c10 project. I am planning to use a 4.25 crank and 4.35 bore to make a 505ci. It’s a budget build so I’m gathering parts as I find good deals. I would love aluminum heads but will most likely have to use GM oval ports for this go around. Thanks for all the great videos!

Chevy. Like to see some SBC 's I know it a dying Breed, Ls is Conquering the BBC and The SBC Gen1 era...

What cam?

@@infamousnova not certain on The Solid roller cam spec. The Amazing thing is the engine is set up for NOS. I'm sure the Cam is big

@@patrioticaussiesams8581 can you find out cam and heads?

@@patrioticaussiesams8581 ??

you can but ramp rates are different, its might be better to do the opposite-solid lifters on hyd cam profile

we use Fel Pro gaskets designed for Gen V

Factory gen 4 heads on a gen 5 block can be a problem but all aftermarket heads work fine on a gen 5 block
