with 2500 stall id say the comp 212/218 (XR265HR)

 

I paid $350 for my cam, springs, titanium retainers, and hardened pushrods. I was 18 years old and didn't know anything about performance plus that saved me over $250 going that route. I am still happy with my cam, but I think I would have been just as happy if not happier with the tr220. I know it would have been much easier to tune.
