It's just waaayyy too easy to throw some bigger jets in there and "let it eat",I was just triyng to help you avoid having it eat itself up,that's all.

As for cams,everyone has their favorites,would help us to see some of the flow numbers if @ all possible to give the best cam recommendations.

Cams are all about compromises.

There are a few things you can try w/the current cam to give an idea which direction to go:

Reduce (tighten) the lash,if it picks up slightly,that indicates it wants more cam.

Advance/retard the ICL,if advancing the ICL picks it up,that suggests it wants a smaller cam,and if it picks up via retarding the ICL,that suggests it wants a larger cam.

And playing with rocker ratios can also indicate such,and experimenting with different ratios on the intake and exhaust cam also help give an indication of what sorta I2E split the combo may favor as well.

But mind you,all that can be a lotta work and track time just to figure out what you may already know.

And I'm sure there something to be had with another converter,be it NA or nitrous.

I know you weren't trying to scare me Bret. I was half joking around, and also realizing you were right at the same time. I never thought about monitoring it with compression tests. That's a good idea.
Thank You...

And I know what you mean about being easy to put a bigger jet in. Ha ha...

See, I don't like the whole idea behind having an extra solenoid to purge. I feel better purging in the plenum. So I just hold the rpms up and tap the button until I feel its enough. So one day I had a 150 in and I was hitting the button and it sounded real weak ( Yes it was a full bottle) So I had a bunch of friends over and they were teasing me saying it was weak. So they talked me into reflowing it and put a 210 in. So we did. I couldn't believe the difference. It went from a lazy rev to a bark. So needless to say , I understand how easy it is to get into trouble because after that I was wondering what a 250 shot would sound like. lol...



As for advancing or retarding my cam I think I'm confident enough to go bigger. Like Probird said , he is .020 @ .050 larger then my cam and has .045 more lift with the same compression and head flow as mine. I know he has a glide and a higher stall but I would bet his motor is making more power.. I will try to tighten up the lash and see if it picks up. The problem is , the closest track from me is 5 hours away. So would a chassis dyno do for now?

About Us

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
