Turbo small block

I think the LA block is good to about 600, I don't know if the magnum block is weaker or not. Don't know much about the new hemi I can't afford to tinker with one.

I rebuilt my 318 and threw 360 heads on it which flow better but lower compression. I am hoping to throw some boost at it when I can afford to. I am doing this whole thing on the cheap though.

I feel like if the new hemi block can handle 600 hp that might be your best bet though. I mean its already got sensors for fuel injection so your halfway there for efi. Id bet the overall engine design is better as well.
