Are these 3/4 or full race cams?

what size motors, heads, comp and intake. thanks. i am iterested.

540cubic inch, ported Dart Pro-1 310cc aluminum heads, 9.5:1 cr, with Dart open plenum intakes

KAAMA why are you selling them? I thought that your motors were ready to go in the boat? What's the plan now?

do you think they will make the same power in my 580ci engines with 345cc world heads minor ported 9.5 comp and merlin intake. can you post the cam timing specs please so i can run in my desktop dyno thanks.

cig 39 did those numbers help you any that i put on your post?

You get tired of hearing that one also.

Cig39,

I would love to sell you the cams and I could be wrong, but in all honesty I think they'd be a little on the small side for the 580 cubic inch engines that you're planing on running. For a hydraulic roller cam, you're going need something with a little more duration than 244* in my opinion...something more like the high 240's on the intake and mid 250's on the exhaust perhaps. Being that my cams are too small for your cube size, I wouldn't want you to be disappointed on the power---but I do appreciate your inquirey.

Thanks, Mark

Hey Crazy,

3/4 race cam huh?....been a looooong time since I've heard that term! Sounds like me 25 years ago when I was a youngin calling up the cam companies. Got a good laugh out of it though!
