I have a 70 chevelle with a 383 stroker, forged pistons, crankshaft,h beam rods,top end kit etc...puttin out around 520 hp. I know this one guy that has a 79 camaro with a stock 454 otherwise the intake manifold. He talks about it all the time but says his bigblock would own my small block is he right? I believe he is terribly wrong:noway:...well i just wanna know who would win?

Also..can i run a 8.2 10 bolt with my stroker?

CHEVELLE POWER:thumbsup:

Only one way to find out: take em to the track and run what ya brung. ;) But theoretically, there are too many uknown variables. Variables such as rear gear ratios, stall speed RPM's (if both an automatic trans) vehicle weights, rear tire heghts, exhaust systems, transmissions used, cam specs, cylinder heads used... and the list goes on and on.

And then there's the driver skills too, and the suspensions used both front and rear, as well as the tire types. Even if you're making more power with your car, it wouldn't mean squat if your car sits there and spins the tires, and his car hooks the tires off the line real good. 60' times mean a lot in a drag race. And as far as hid 454 engine being "stock"...well...if I had a dollar for every time I was told that by other racers who had modified cars, I'd be filthy rich. :yes:

I love this answer!

yeah,are you SURE your 383 is making 520hp? An awe-full lot of guys THINK theirs do but get royally spanked by 454s.:yes:

I think you would win, Ceasar, because you have a Chevelle and he has a Camaro.:D

As the others have said, there are a bunch of things that would factor into who would win. I think it is safe to say that he would not "own" you, and from what you've posted I would put my money on you to take the win.

On the street, your 8.2 should live for a while becaue the tires will break loose before any damage is done. If you plan on racing at the track and with sticky tires, you may be pushing it and it may not live so long.

The late seventies Camaros are extremely heavy, even with their small blocks they normally weigh over 3600 lbs., i'd look for this one to be about 4000 lbs. or more with the driver on board. A 3500 lb. well built small block to beat one rather easily, your aquaintence is retarded if he thinks a stock BB with those gears will beat your lighter Chevelle.

2.73 gear was common back then. Z-28s had 3.42 if automatic or 3.73 if 4-spd. So if he has a Z-28...
'stock' 454s can be brutal if not totally stock. Basic deal with a small cam can take a 70 Elky well into the 12s...I did this last year. Pretty easy to do the same in a Camaro.
I must admit, I am curious what is in this "520" horse 383.

I just say whoever can put the power to the ground will win

as long as the info were looking at is definitely accurate then there would be no owning done by the 454. With an honest 500 plus horsepower, those gears, at least a ballpark torque converter, and the ability to hook it up..... you should run 11's any day of the week.

if he is truly stock(and by stock....i assume its a run of the mill stock 454), then he isnt even in the same ballpark.

Both cars are street cars full interior...just lookin 4 some street action.
And HELL no it aint the ls-6...its out of a truck.....

I just dislike CAMAROS....
Street action NOT cool. FYI street-racing discussions on this forum get deleted quickly by the moderators. Do it at the track, keep it safe and legal.
Ditto on the 'stock' 454, do you reallly know what he's got in it? Big blocks are torque monsters, but it boils down to who can hook the power to the ground better.

Not trying to be a d%ck but....

Lets see, pay $20 and take it to fontana run with no consequence or run it on the street risk killing someone or getting your car impounded and crushed. You know thats wht they do out here right? It only takes one time and bye bye car. Dont be a squirrel...that stuff gives our hobby a bad name and encourages laws that crack down on these cars to have them taken off the road..

Get to the track and line em up theres no crystal ball to tell the outcome.
Telling ya spend a night or two out there and you wont want to streetrace again. Youll have a blast!

Actually the small block is exactly 145 lbs. lighter when both had cast iron heads. I've weighed both in a '67 Camaro and the difference was 2740 lbs.(sb) vs. 2895 lbs. (bb). The car was a gutted race car. The small block has way better gearing than the BB Camaro so it should accelerate much better and be a couple hundred, or more, pounds lighter. It also must have a good set of heads to make over 500 h.p.

I know this forum is heavily slanted towards the BB, but c'mon guys. He said stock. Stock '72 LS5 454 big blocks only made 270hp and it got worse after that. When people hear 454 they automatically think of the '70 LS6, but I'm doubting thats what the guy has.

Actually a pretty good mix here.
I do like both SBC and BBC engines....have had many over the years. But is takes a lotta time, money, and effort to get a SBC, even a 383 to run with a mildly warmed-up 454. This kinda 454 will go into the 12s with street gears.

Seems the fixation here is horsepower. :sad: Wrong way to look at things in street performance. You need to look at high average torque AND getting the power to the ground right away, low 60' tiimes. Another thing is tune and tricks of the trade.

I'm not seeing the OP's "puttin out around 520 hp" :sad: sounds to me like a lotta other youngsters thinking they have something they do not. Got a parts list? Not saying you can't do it but not a kid's car on the street

Harold,

Good response! I'm sure all but the show car and Numbers Matching guys have ditched the iron intakes and exhaust manifolds....could be more lbs full-up factory stuff but your 145# difference in hi-perf dress sounds right to me. Aluminum heads and WP would cut way into that weight difference....ok, I am moving away from the thought of the thread here.

I know wat i have since it was built in a speed shop...I know at the end its just the dyno number and i need to still factor in the fact of how much power im puttin on the ground and hopefully ill beat the BB cuz i know how deadly they are. But the owner of the camaro dont know nothing about cars...he just bought the engine of a for 900$ and just changed the intake manifold and the valve covers...thats it! I've spent 2 much money for my engine along with my cars,suspension,tranny and i sure hope i beat him..i know i have the parts

One guy with a 383 that he says is putting out 520hp....& another guy with a 454.....that he says is stock:rolleyes:

thats about all we know.

OP Cesar,
In trying to figure this race out, we have asked for details. You have provided none.
If it is a pro build, you should have the info.

Correct, a 70s truck 454 was not a 1970 high compression LS-5. But, throw on early heads and any but the smallest cams out there, and you have something pretty nice.
Paul '65lkey' here has some shaved early heads, 94cc....sure to wake up a smogger engine. The factory 454 cam was small in a 396, pitiful in a 454

I say you and your friend go down to the track, make a few passes. Say best 2 outa 3 or 3 outa 5 wins. Meet up back at home,
loser buys the beer ... err uh Red Bull (forgot you're 18 :D), and call it a day!

If your that sure of your motors power, take him to the track and spank'em :boxing:

350hp;)

we all know it doesn't matter HOW much power you've got ;) if it won't hook your getting your hat handed to ya by granny in her VW l:)

I used to give my buddy a ration everytime he showed up my LT1 sbc would plan flat leave his 350 hp 396 needless to say he wasn't real happy about it ;)
