Hypothetical 318 Builds

My next teener will be with 'J' heads and another set of forged TRW's, yep outta another mariner engine!
Steel crank from a 273 and 340 rods that have been lightened and polished etc.

I want to get her up to around 7500rpm's hopefully.
I just love a screamer...:realcrazy::realcrazy::realcrazy:
