Default Re: Cam specs for Ported Heads

I'm curious too. Given a set of heads ported to "today's" standards, what cams would work best with ported heads on a 350, 368...so on. Drivability/intended use aside.

Sounds like the "while I'm there" bug has hit. Xfire just spent lots of $$ on ported heads and doesn't want to put stock cams back in! I'm in the same spot.

When I re-did my Xfire I read up on cam selection including some of Vizard's work. Seems obvious that the stock cams, altho working well, don't take full advantage of the additional airflow. If you're going to do the job, try to maximize the power output. On an SBC, it's easy enough to play with cams.
The LT5, not so much. If Marc H. is lurking maybe he could chime
in.

I am about to be in the same spot. How about a limited group order and a discount !!!??? I have a 350 cube motor and will have ported top end inc. TB. Just about out of money for cam grinding even though I have a core set of stock ones to hand over. Would love to pick up that extra 20-25 ponies at the wheel.

Lee,

Could you post the ISBN# for that S. Hyland book? (ISBN# usually on the back - often next to the a bar-code.)

It would make for an interesting read.
