The comp cam ran out of steam fairly early. I think the short intake duration, 110lsa, and 4 degrees of advance wasn't ideal for my engine. It blew over 190psi, closed the intake valve at 60 degrees ABDC; i think too early. Put it in straight up would help or use in a low compression engine. I was 9.31 compression. Ironically a tappet failed and i needed a cam quick and tried the 272/.455 and it was 3mph faster in the quarter. The Engle/Hughs 2330 ran the best combined with a pocket port; picked up another 3 or 4mph.
Of all the small cams i tried in a near stock engine none really picked up rpm. All improvement was between 2000rpm to 4500rpm. Never found wider lsa to be a killer, in fact the opposite. The 6401 is just an easy step up from stock. The 272/.455 coupled with 1.6 rocker is an over achiever. I think the Engle would have been a little better with a little wider lsa.
I've got a few new shelf cams i'll never get to try. I think i'd like to do something custom for the kind of work we were doing years back.
We here a lot about the mr. 6pak cam and it's an Engle. pretty sure it's very mild with a 114lsa.
Good stuff. Thanks Lew.
