A friend of mines just put a chevy 454 in his 87 gran prix, they say its mostly stock but it has 11.1 compression, and dome pistons, so he is always talking crap about wanting to race, I was told that the motor should have around 460 hp, I wasnt concerned at first until I found out the compression, so now Im really thinking, with the extra weight of the engine and the car, will I have a chance, or should I just get the bottle and suprise his a@ss.

and I should be pushing around 415hp with heads and intake and other internals, should 1.7 rocker arms, o/f bbk h pipes, hooker 351w swap headers, flow master 3 chambers, and a k&n air cleaner make a difference. I hear a lot of people talk about exhaust and k&n air cleaners dont make anymore hp, is this true.

Take off the air cleaner for the race, thats a easy couple HP.

Only way to find out is if you run him...

Yeah, I'm running a carb also. I have dyno sheets to prove the HP gain. In fact, in my case I gain 14 HP with no air cleaner!!!

No matter how good a air cleaner is supposed to be, ALL cleaners / filters restrict incoming air.

Ther has to be gains from a complete aftermarket exhaust system over stock I was led to think 20hp at least and a few with more hp with K&N filters. His car is a big beast but yours is a beast in its own way. He may have a little edge but not that much and a good driver could even the gap more, I would hope you would win, but it's a close call.

thats a good thing to know, man I wanna kick this guys a@s, he thinks all because he has a big block 454 he is untouchable, and no small block ford can touch them, I was going to put a bbf 460 in 95 but didnt wanna go thru the hassels, plus nowadays small blocks can push out more hp than big blocks with the right mods

What trans and gears does he have, what do you have? His car isn't as heavy as you think, if he has good gears exhaust intake carb, I'd put my money on him.

He has a 350 turbo, not sure about the gears but I dont think anything special, a bg 850 bg carb, and stock headers and flowmasters, the exhaust is cut in the middle of the car, I drove the car last week and it didnt impress me too much, it had hella tq thou, but since I havent drivin my car since december I forgot what tq feels like.

You definitely have a weight advantage. The older GPs are probably close to 750lbs (assuming you've done NOTHING to strip your interior and lighten it which may not be the case) heavier than a Fox mustang. You're at about a 50hp disadvantage but that may be countered by his size. I've personally always preferred the power curve of a small block and that may also work to your advantage.

Bottom line is: Tough to say. Drive your car like you stole it, and let us know how it goes down! Good luck.
