Unfortunately I didn't build this myself and I have limited information on the engine specs but I do have this link,
Mopar 225 Cam & Kit 268 Mechanical this is the set up that the guy told me is in it, it was converted to big bolt pattern, and I believe what I said, "it can't put the power down", isnt the right thing to say which is what some people are confused by it but what I mean is that if I give it full throttle from a stop it is obnoxiously slow and think this is due to the rear end which is why I am looking to swap it. Please correct me if I'm wrong on any of this because I'm still learning.
