The 2 builds were 99% identical, the only difference was intake. 50lbft or torque at 3000rpm is a BIG deal, and its all in the intake, Im 100% sure of it. I have seen it many times, this is just the most recent.


Thanks Mike! The thought was the intake might be not fully utilized if the cam was small. Given that info I agree on your assessment here. Sorry if I was being difficult.
