Hello all
I need some input on engine choice here...


I have a 69 Mach 1 in need of restoring/hotroding. These are the options I am considering:

1) The car came with a 351 Cleveland, condition unknown. The engine was transplanted 20 years ago but was never fired. The Heads are not marked with a 2 or 4. they are casting DIAE-AIC. It is a Cleveland

2) I have an FE block that is a 352ci. A friend at work wants to sell me a 427 (steel) crank with rods. That would make it a 390.

3) I can start from scratch with a 460

What engine do you think would bring the best value per buck to the Mach 1?
Thanks
