Hey Jules,
I mentioned the 351w because I believe he already has the engine,I was thinking with the right head,cam,and intake/carb combo that 351 could run. That said if 351 prices make you throw up in your mouth Go price some 428 C.J. Stuff,The Throwup will fly out of your mouth and go all over your shirt,pants,and shoes.LOL.... Sorry you started it.
P.S. Jules,What motor are you looking to go with in your 69?
