Okay I know my motor has issues and stuff but i raced a 03 chevy z71 and it always sucks me up and passes me towards the end of the race. Im looking for top end on my motor. any suggestions??>

 

SOUNDS LIKE YOU NEED THE HYPERTECH POWER PROGRAMMER

 

What do you mean by "issues and stuff"? If you are already not running at top notch, there's no point in trying to soup it up even more!

 

You really think an extra 3 peak HP will make that big of a difference? There's a spot in the midrange where he will hain 7hp, but it still won't do miracles!!

 

Well i have very bad compression. Im getting a 318 thats used with only 60k on it. My first things i want to do before motor goes in and truck is put back together is.

1.7 Harland Sharp Roller Rockers
Dual Electric Fans
M1 intake manifold
Underdrive Pulleys
SCT Flasher

You think that will rack me in the high 14's?

 

that would do ok... but a 360 would do a hella lot better.

 

What do you find your problem is at the track? Post up some slips.
What are your 60' times like? What are your trap speeds? Little bolt on stuff won't do much.

I would change the gearing as my first and most effective mod. Are you still runing an open diff? If so, that's garbage, so throw an lsd or locker in there so that you can put the power to the ground.

If you show us some slips, we can get a better idea of where you are now, and what can be easily improved. Also, have you checked why your compression is low? It could be as little as a gasket?
