Greg Hackman has the best cam right now in my opinion. http://www.smallenginesofseymour.com/camshafts.html

I've got a Hackman cam in my tractor and it's been the points champion for the last 2 years. I'm building another tractor right now, V twin, and it also has a Hackman cam in it.

Do they check the lift at the valves when they tech your engine? I run a .340 lift cam with more clearance in the tappets. Keep adjusting and checking until you get the .330 lift. It won't be nearly as much clearance as you think. I have a slight click at an idle when cold but it gets a little better when it warms up . Some of it due to strong valve springs, some due to cam profile and some due to the tappet clearance. I'm not changing anything though, it runs like a bear.

I think the cam grinders are optimistic when they list them as .340 lift.

thanks,,, and so far I have not been teched because the club i pull with has 1 "stock" class but the only limitations there is 4600rmp and tire size. how would i check to see if i have it adjusted to .330?

Put a dial indicator on the top of the valve with the valve seated, roll the engine forward until the valve is at maximum lift, set your tappet so the indicator reads .330, then roll the engine through a cycle and check it again. Do this to both valves, bolt the head on and go pulling.
