Big Block Owners

Two questions for people with stock mount location BBCs.

How tall is your intake manifold from the intake seal to the top of your aircleaner?
What kind of hood are you running and how much space do you have between the two?

Thanks.

Re: Big Block Owners

13'' inches, big block style hood about 2.5" rise, and about a 1/16th to an 1/8 of space between the top of the cleaner to the bottom of the hood.Name:  100_0955-1.jpg

Re: Big Block Owners

Bingo.

My tunnel ram setup should be about 12-13 inches and seems will fit under even a 3 inch cowl. It's a Holley Pro-Dominator Tunnel Ram converted to EFI, gonna get a 4150 top for it and use two Accel 1200CFMs. They are only about 3.5" inches tall and the intake is 8.5"

Thanks a bunch 92 BBC Z.

Re: Big Block Owners

The BBC has to be the best looking engine ever made. Amazing. If only there was a way to fit one under a stock hood for a stock look.

Re: Big Block Owners

Judging from here you would need a 10-11" setup to fit it just snugly.

If you converted to EFI and used a short TB instead of a carb I could easily see sticking one under a stock hood while using a single plane and making great numbers.

Most intakes seem to be about 6-8 inches tall, and the two EFI TB i've checked out are are 3.5" tall.

The problem most people have is a carb is about 7 inches tall. That extra 3.5" inches is where cowl hoods are needed.

Re: Big Block Owners

I believe I could fit a BBC in with a stock hood without to much fuss. Would require a shorter intake, like a Performer, or another type of single plane. By the way Parasoth, I forgot to mention that the current motor is a standard deck(9.8) but I added shims(washers), about 5/16, to the engine side of the mounts to try and mimic the installed height of a tall deck(10.2), cause thats what going in next. Furthermore, there's a 1" carb spacer, and get this, a 3.5 aircleaner spacer underneath the drop base cleaner(needed for throttle clearence). Not to mention the aircleaner itself is a couple of inches thick. Hell, if I were to remove all that and go with that Spectre low fit with those side filter's, it'll probaly close with a stock hood. Of course thats just eyeballin'.

Thanks man, I appreciate that, especially from another BBC 3rd gen guy. I've always admired your car, but I cant help but wonder what she would do in the "Mile" with different suspention, gears, and rolling stock? north of 200mph is my guess.

Re: Big Block Owners

How much power are you making? A 3200 pound car needs about 800 RWHP to have a shot at breaking 200 MPH.

The deciding factor in top speed is aerodynamics more than weight. 3rd gens only need about 650 HP at the crank to hit 200MPH.

Re: Big Block Owners

Actually I was wondering about 1BADRZ28's 555. Its got the 650rwhp more than covered. Oh, and by the way, CPE's 89RS BBC, went 193mph with only 530hp @Ohio's TRC .They used alot of speed tape( no pun intended) on the front but they did it with a ZF-6 and 2.94 5th gear. I have a pic of the car doing this but my scanner is broke, so I'll do my best, with what I have. Wait for it.

Re: Big Block Owners

I was mainly referring to a real world street car.( 3400lbs , full interior ) More to the point of Gale Banks twin turbo cars back in the 80's went 204MPH with 650HP, were my point of reference. btw very clean work

Re: Big Block Owners

Its was this car from C.P.E(Chevrolet Performance Engineering), and The 'Keith Black' camaro that were my inspiration to build 200mph capable, street driven 3rd gen.
Thanks for the compliments.

Re: Big Block Owners

... Do you guys have any proof to back up your claims?

A 4th gen Camaro and a Z06 are far more "aerodynamic" than a 3rd gen could ever hope to be.

http://www.bangshift.com/forum/showt...to-hit-200-MPH

The second link is a good read, that last 7 MPH he needed for 200 MPH could easily have exceeded 200 HP.

Might want to rethink your goals.

Are you sure the fourth gens are more aerodynamic? the Thirdgens have a pretty good Cd, the Firebird being a good bit better than the Camaro, though. Ive got no doubt a newer Vette will trump the third gen F-bodies pretty handily, though.

The 85-90 GTA had the record for stock body'd car speed record for years and years.

Re: Big Block Owners

When the IROC series switched to the 4th gen they found the 3rd gen formula's were slicker (lower dragcoeficiant) than the 4th Gen's. they could run 185-190 with motor's that made 475+/-at daytona. (if i remember correctly)
