yeah, i notice the engine feeling kinda out of breath at about 6, so figure a 272 delta cam and some port work done to the exhaust port would help remidy that problem. I have a friend who learned how to do head work, so that will be in order after i pick up another head from harrys u pull it. I figure that after opening up the exhaust port, 272 cam, the t3 i have should make like 10 psi between 3 and 35, would i be wrong to assume this?

 

i could just use the cam right? i don't have to replace anything else right?
