What is the biggest engine I can put on my 1979 Ford f150 custom ?
If it is a Ford engine, you can put a 429 Boss Big Block. It is also the best engine Ford makes.
a cheaper route would be a 460.
I totally agree. But if you are not looking for a hot rod motor, I would suggest a 390.
I see you like Chrysler products. So do I. I won't even consider anything but a MOPAR.
