The MOPAR power myth?

I'm lucky enough to see some bad *** engines and what there really making.

I had ideas about what I wanted to make and how doable it is. It's way cheaper to make big power in a brand X.

Why is no one in the big money cars running a RB block?
The mopar blocks won`t take as much h.p. as brand x, They break between the cam and main bearings. Mopar heads are sucking hind tit compared to other makes also. Mopars run good, till you get in a class where you have to have (BIG HEAD FLOW,as in prostock.
