yea stock internals should hold up to a 70 shot pretty safely, according to a couple of my buddies that work for honda, also i do some side work for a local shop ,hybridynamics, and we have put many kits on with no trouble.. if i blow it.. man that would suck,, we have done over 45 swaps and i can get a motor pretty cheap or better yet send it to javier at jg edelbrock and have him biuld the **** out of it
