Sorry I'm not trying to highjack this thread but I have a question for Cliff R. What do you have done to an HEI that it makes 1 more horsepower than a billet MSD. The reason I'm asking is I'm getting ready to buy a distribtor and if I can get an HEI instead of a billet MSD I will.

Thanks Greg

Your cam sounds (exactly) like the one Bullet recommended for my 433 engine.

However I have only 9.8:1 compression, and 255cfm heads, and asked them to recommend a cam with max HP at 6,500rpm.

Based on them being correct (I have not tried it yet) I would say your camshaft is too "small" for your better flowing heads and higher C.R.

I agree with ScreamingChief, try a camshaft with more duration.

Good luck and have fun!

My DUI HEI and a MSD billet with a 7AL box on the dyno were identical.

I heve picked up without an air cleaner. I forgot my longer carb stud for my setup to do that at the track. After clicking 10.99 and 11.00s I figured that was fast enough.

Cliff Ruggles just rebuilt one of my Pontiac HEI distributors for one of my 455 street engines, i had him install the Mallory rev limiting module also. Got the HEI back from Cliff and very happy with it, thanks Cliff, you do very nice work.
