OK NOW THE PROBLEM. I HAVE BEEN TOLD THAT IT SHOULD BE MAKING AROUND 310 OR SO HP AND ABOUT 370 TQ. THERE IS NOW WAY THAT IT IS MAKING IT THOUGH. ME AND MY BUDDY RACED IT AND MY MOMS GRAND AM AND IT LOST!!! LOL BUT ANYWAYS THE CAR (85 TA) SEEMS TO LOOSE ALL POWER WHEN IT HITS SECOND GEAR. I HAVE BEEN TOLD THAT THE TIMING IS OFF SO I AM GOIN TO ADJUST IT BUT I REALLY DONT KNOW HOW IT SHOULD BE SET, ANY IDEAS? BUT MOST OF ALL IM TRYING TO FIGURE OUT WHY THIS CAR HAS NOT GOT THE POWER THAT IT SHOULD HAVE. ANY IDEAS ON WHAT IS GOING ON?

 

The timing being off can do it, i lost a whole second in the 1/4 mile when mine was off by 10 degrees once.


I'll let someone familiar with your heads give you a number for advance though.

 

what should the timing be set at?

 

for my 350 same set up, i think i ran base timing at 16 and advanced at 32 reving at around 2500. hope this helps.
