Re: new cam
 

check your firing order on the distributor and plug wires :)

Re: new cam
 

lemme guess, your car is NA stock compression ratio.

Re: new cam
 

all stock exept cam

Re: new cam
 

There ya go, you're overcammed. You probably lost more power in the low-mid range than you gained on the top end. If you gained anything at all.
There's more to building an engine that makes usable power than buying everything that says "stage2" on it.

Re: new cam
 

very well put

Re: new cam
 

Were stock specs the recommendation of the cam manufacturer?

I agree with klyph

Re: new cam
 

I'm going to guess the engine isn't in time.

Post your cam card, homeslice.

Re: new cam

Re: new cam

Re: new cam
 

How did you time the engine?

Re: new cam
 

probly not.


my guess is he skipped a tooth

Re: new cam
 

I bet he tried the 9-3 position instead of 7 o clock Charlie bomber.

Re: new cam
 

no its at 7
almost sounds like valves are to tight have them one up from stock spec?

Re: new cam
 

Uh, let's go back. Why do you have a huge cam on a stock motor? As has been said, you probably lost a lot more than you gained. Bigger cam without higher cylinder pressures means lost power.

Thanks for answering my question, and being serious about fixing your problem which is illustrated by the full details of your setup, what you've done to the car, and timeline of events you have posted.

Hey, here's another question for you to ignore: why can't you get the car to idle with your tuning gear on it?

Re: new cam
 

Do you guys mean he lined up the "up" mark on the cam pulley straight up, instead of using the mark near the 7 o'clock position on the upper cover?

Re: new cam
 

yep :)
