I am building a similar 400+ HP 350 this winter and were all pretty much the same weight, so I think we'll be able to kill them.

Maybe even take a newer corvette...?

I would say you could take the newer LS1's if you got your cars tuned and running right, just remember, the 325 HP or whatever rating they have is B.S. They have closer to 340-350 HP at the flywheel. But you should be able to take them. A race with a C5 would be pretty close I dunno, you could probably edge him out.
Edit: Oh he has an LT1? A pretty quick car, but you would take him pretty bad if you have 400 HP.

You need to upgrade suspension so you can hook up also. I think the newer cars have that advantage over us too. They can hook up better.

If you really make that much hp yes no problem but, how do you plain to make that kind of hp? I can take the new ls1 vetts to 3rd gear but, thats when they finally pull up. I have 300+ rear wheel hp and tons of torque I for got my numbers but will find my dyno results yet again. If I had 100 more hp I would walk them. no question

what suspension things work the best?
i was gonna get sub frame connectors but i didnt know if they would help much or not

but they lift bars seem like they have a good idea but i was talkin to my friend that has the 94 Z and he said that all that does is just push the wheels down more and they still break lose

now that could just b his guess...is he right or wrong...and would you recommed getting those or are there ground clearance probs with them?

and i plan on doin this with the System max 2 system from holley
here is the link to it
http://www.holley.com/HiOctn/ProdLin...K/300-503.html

or you if you the new jegs catalog it is on page 61

the guy that is doint most of the work on my engine said that it should b able to get the same specs as that but i doubt it cuz i dont wanna start gettin big headed bout my upcoming motor

LS1s have much more than 350 horsepower at the flywheel, more like 370-400 depending on the model. Some camaros dyno at 300rwhp stock, newer corvettes have closer to 350. With 400 horsepower at the flywheel you will not be able to beat newer corvettes.

You can take LT1s easily, they are high 13/low 14 second cars stock, while you could get in the low 13s and possibly high 12s with that much power.

Mark A Shields

And what kind of tranny will be backing this up. Neither a stock 700R4 or T5 will handle that power for long.

I don't see how a new LS1 will have 400 horsepower at the flywheel, when most of them dyno at 290-300 rwhp stock. 340-350 I would believe some could produce, but come on, look at the drivetrain loss factor...that's over 25%! If the motor has 400 horse, and the drivetrain robs it of 25% power, and then it would dyno at 300 rwhp.

Not flaming, just saying that 400 is a little unrealistic.

what would i have to do to my 700R4 to b able to handle the power?

Violate 3.8

I used to have a video of a stock ls1 dyno, and it was 407 hp at the flywheel. I couldn't believe it, those motors are crazy.

Dano 00TA

If you can hook 400 ponies you'll kill LT1's and probably beat or be real close to a stock LS1.

if you can hook and are making a true 400hp at the flywheel. Back it up w/ a worked over 700R4, get some 3.73's, good tires, LCAs, LCA relocation brakets, adjustible panhard rod, and SFC's. You should be able to walk LS1's in the 1/4. You have to make sure your **** is tuned up. If you're going to use the stock Carb, that'll rob you of some power if you don't get it built right. If you're gonna go w/ the Holley carb, cut the computer out, and have fun. It's doable, don't get too ****y too fast. There's ALWAYS a faster car around the corner.

heh if all you want are 13's from a 400 horse motor you wouldnt even need traction goodies. 400 horsepower has 12's written all over it.

well see that is what i was hoping for
cuz i dont have all the money in the world

im hoping i can build up the tranny some and just put in the engine and then downt the road when i want faster times i will do all the goodies
lol

What everybody keeps forgeting is; whatever you do to your TPI car(mods) the LT1 or LS1 guy, can do as well. Chances are the LT1/LS1 cars are also modified. Kind of sucks, eh? You are playing pointless catch-up, no?

I have a 93 but I have less than 400 hp at the crank and am knocking down 12.39s at 111. Havent seen too many LS1s naturally asperated stay even clost to me. The third gens suspension is very simular to the 4th gens (in the rear anyway) so if you can plant it you'll smoke em good.
Perry

Perry93TransAm

As some reccomendations for the motor, I would run all your money into the heads. get you some good heads and have them ported. The cam I would use would be a cam with 220 int .050 dur and 230 exh .050 dur about 520 lift on both sides and 112 degs lobe sep. Run a 3000 stall and some 3.73 rear gears with a 26 inch tall tire. Get a stand alone controller for the tranny to give you the ability to lock it up as you please, independant of the factorty computer. if your car is weighing around 35 to 3600 race weight , and you hit 380 to 400 hp you'll smoke em good.

yah i am gonna use this system from holley called the system max 2
it comes with the whole setup
just go to www.holley.com and check it out
it said 425hp and same torque but i was guessin 400 cuz nothing ever seems to turn out perfect when i try and do soemthing to my car
lol

i already have 3.73 but i need a posi, i have 245/60R15's

and i was gonna get that manual lock up but with a 2500 stall instead


thanks for the post!

Perry93TransAm

Those are some good heads, what I would do with them is smooth them out in the bowl area even more (not remove alot of material just blend into the seat) this will help some, not sure of the specs of the systemax cam but if its making 425 horse on a 10.0:1 motor its probably pretty good. remember your heads flow the air its just the cam that holds the valves open, i.e. more heads take less cam to flow the same amount of air to make the same power.
