New Hawk, new adventures.

There are quite a lot of cam profiles out there for these motors. The main reason I went with the current WGK cam profile that I do have is because it required no other engine work since it adds no lift. The second you increase lift and duration on the CG engine design the first limitation you run into is the valves try to become best friends with one another during overlap. The simple solution is to machine back the valve seats so the valves sit deeper into the head.

As I have tried to explain to other guys obsessed with trying to do the same work. If their goal is more horspower, a cam is a better option than a bigger cylinder.

I also wouldn't bother with a larger bore without having some head porting done at the very least.
