I would think a a Gen 3 with a turbo kit also, but you could also easily run the bill up to equal or far more than your basic B/RB would be to make the same power. It all depends on your approach. But I think it can be done cheaper. The main disadvantage that you have with a B/RB is its already going to need a rebuild unless you find a good engine for a song. Everyone thinks their junk 440 that burns oil and has 100 psi cranking compression is worth what those 5.7s on CL cost...
