Who builds reliable race/street engines?

lots of good suggestions
Bp engines, IMM both top choices
I do my own machine work so trying to be impartial here
other choice with less aluminum cans is to wait for a 40% off day at pick a part and grab a complete 360 magnum (take a battery and check compression but all I've done did not need a bore job) you want one that was wrecked not in the yard for some unknown reason, obviously check the oil
now your headers fit and you will need to drill your heads for your manifold or get a different manifold- there - done- use your waterpump
need an electric fuel pump - lots of threads on this and websites that specialize in this conversion
Slantsix64 lives near me and did a DIY- see his thread
cheers no matter what you do
if crate start with a roller block
