I got this motor off of an old guy that never went over 50 mph ever. So the motor is in excellent shape, it still has the cross hatchings in it from the factory bore. Im not too worried about cooling problems because it will be a standard bore, and I havn't had any problems with it yet, I used it a for the summer in my camaro.
I don't know where these people are coming with when they say that too big of valves are not good, They said with 2.08 valves, my motor won't start running well untill 4000rpm, but I guess they don't know what they are talking about.
Are those Desktop Dyno programs accurate??? I was thinking of matching up a cam using that program.
