!!! -- waits for a reply

 

Well as long as you have the car ready for all out drag use. I wouldn't worry about what it will run iu woudl worry about a roll cage, mini tub, and a lot of other safety things. That motor if equiped with the right tranny and rear end and safety stuff is an 9 second car if not lower car. Usually you don't ask what it will run if you are making a combo that serious. You should already know what you are getting into.

 

I saw a guy put a big block in a 3rd gen and the roof buckled.

 

well i am thinking mid to low 9s at 150+ mph it will be a turbo 350 with a brake stalling at 5000 rpm i am going to try and use a 10 inch tire for that 10 inch tire class in nmca

 

i'd say 12.30s at about 125 with no traction

:lala: :lala:

 

lol, I second that

 

turbo 350 won't take it, have to go 400 or a glide

 

:hail: 555 :hail:.............. that is awesome. plan to do this all day long.

 

i think the front end will be 2 foot in the air

 

i have a pic of a nice 3rd gen that runs 8's or 9's in the 1/4 where we race that does about 3 or 4 foot wheelies, have a pic of it where it is coming down, but still up nice, i know a crazy guy that broke his wheelie bars off his 3rd gen and scraped up his bumper.....now that would scare the crap out of ya....i know it would me
hail to the big motors and wheelies

 

Yea poppin wheelies is cool!

 

no you won't, the nmca doesn't exist anymore. pro-media bought the name and hasn't done anything with it yet. but you can come run with us in the nSca if you would like. same great people, different name. any idea what small tire class your looking at? low 9's/high 8's isn't good for anything but the n/a small block classes.

 

why put the above mentioned combo in a 3rd gen? It's going to cost 3x what the car itself went for. Stuff it in a Vega or something for 1/2 the weight and torque over onto the roof-- 3rd's (for a multiple of reason's including the above mentioned roof/frame BUCKLING) don't make radical strip cars without extensive body/frame modification/rebuilding. At that point you might as just well go Funny..... which is about where this conversation has landed....

 

you can put cars together that will run 7.50's before going to a full tube frame car. just run a good 12-16pt cage and good suspension. the motor he is talking about is much more mild then you think. with the power he wants to make he will see mid 9's. yeah, that's fast next to a street car but it's not really that fast. go to www.nsca-racing.com for some really fast street cars.

 

just realized something else. have you ever driven a short wheel base car really fast? ask anyone what they do on the top end of the race track.

i say more power to the guy but he will either need to spray the ***** off the motor to get it competetive in the Nostaglia Pro Street class or put one bad n/a mouse motor to give the Hot Street guys a run for the money.

 

I think motor city mike is pulling his front tires a few feet and running 8's or 9's.

 

Like the above post said, if you're getting that selective with the combo you're considering, usually you've played around with dyno-simulation software and know more nouns about your selections than a bunch of ad-copy numbers and the general published weight of your car. And if you're looking for a strip car, your first choice is *probably* not going to be a 3rd gen. If you want to build one, power to you. But if the engine is being custom built for strip purposes as the lead post in this thread indicated, I don't understand the choice of delivery. The unibody alone requires alotta work and dollars to strenghten. go with a full-frame anything and know you're planting your torque with minimal risk of frame twist.

 

The trouble you're going to have with a 555 is that it's a tall deck block. This means there's going to be even less room around the firewall than a normal short deck BBC.

An engine that big is also going to need to breath. Forget about using the cheap small Hooker Supercomp headers. Something from Lemons or Ed Quay will be needed at somewhere around $1000 for a set.

All that power means nothing if you can't get it to the ground. A complete chassis upgrade is also needed.

 

if all youre looking for is 9's why waste your time with a 555 motor??? My buddies dad has a C4 running consisten 9.7's with a turbocharged V6 under the hood.

 

Sorry man, but that Turbo v6 is a bad idea, not to mention in a Vette (Great car, but not exactly your straight line kind of ride).

Dont know too much about BBC but a decently built 400sbc will get you there on the spray pretty easy and probably much cheaper (easier).

Get your suspension figured out first, lose some weight, and you will be running some good times on any sbc/bbc.

 

Why is it a bad idea? While maybe an IRS setup is not ideal for a drag car, the thing is 100% street legal, runs 9.7's on ET streets, and handles like a bat out of hell. While i wasnt sugesting to use a v6 my point being is that if youre looking for 9's there really is no need to go with a 555 bbc

 

I wouldn't waste your time with the BBC. A tall deck BBC
at that! I will need at least 2 1/4" diameter custom made
headers (BIG $$$), A 33 spline axled 12 bolt Chevy rear ( BIG
$$$), and race built TH400 ( not as BIG $$), ALL of your
suspension redone with at least a 10 point roll cage( BIG $$$)
for rigid area and of course, safety! Also will need to modify
your firewall and steering shaft clearance, among other things
to fit that bad larry under there. So, it's not practical, but
possible and VERY expensive. I personally would stick with
a SBC 350 block, and max bore it and max stroke it to 430
and get like 470hp out of it and then maybe supercharge
it or dump some spray in there to up the hp to 600hp.
Of course , even with that you will still need a 10 point
roll cage and totally modified suspension,brakes,trans. and
at least a 12 bolt Chevy rear to hold up the power. I think
you also need a new hood to clear everything too.

It's just easier and more cost effective to run a SBC under
a thirdgen hood! My opinion. But, If I had the money, fab/welding
skills I would be putting in a 502 Ramjet under my hood.
But, I can also get 502hp out of a built 430 SBC too!

 

WELL said! You DON'T need a BBC to run 9s! You can do it
with a SBC or even a 3.8 turbo GN/TTA motor!

IRS is not ideal for 1/4 mile, but put that exact same 3.8 turbo
in a thirdgen, watch out!
