Fishy68, thanks for the info on the rockers. I think I may try those instead as long as they don't use a ball/cup pushrod. So with those rockers I was thinking about this cam.....Let me hear it:)

The Harland Sharp rockers do use ball and ball pushrods. If you only had 9.5 to 1 compression I'd say yes on that cam but... I ran it on a calculator and if I did it right your engine is going to be 10.72 to 1. That's alot of compression for a small cam even if you do have closed chambered heads and zero deck pistons. I personally would prefer a little bigger cam, about 6-8 degrees more duration, so I'd know it'd run on pump gas. The Mopar cam looks better (because of more duration) but like Moper and me feel they aren't the highest quality anymore. The last one I degreed in was 8 degrees off. That's junk in my book. But I do know guys that have gotten good ones too. It just seems to be a crap shoot. Something else to think of is a custom ground cam. That way you can get the duration without so much lift. Jim @ Racer Brown is a super nice fellow and very knowledgeable about cams and you can probably buy a custom ground cam from him for the same price an off the shelf cam costs. The last one I bought from him was only $250 shipped for cam and lifters. Jim's # is 410-866-7660 and the best time to catch him is 2-9 pm eastern. You might give him a call and see what he says.

Fishy that's a nice set of rockers for 300 bones man.
I didnt know they existed.

And those racer browns are nice too!

They sure are a great deal at that price. Alot of generic ones are close to that price and aren't near the quality of Harland Sharps. I think all three brands mentioned here are real good rockers. Just the price is so much lower on the Harland's.
