I'm bias towards the all alluminum LT1 (Cause I own one)

for got the 7.3 power-stroke but the 6.0 has to go sorry but the 7.3 was so much better of a power plant

4.6 was a great one as well as the 3.8 SC in the super coupes

Chevy 350 v8. It'* easy to work on, easy to modify, relatively speedy, and takes all the **** I can throw at it, then laughs at me for thinking that it would be fazed. My truck pulls trailers, flies on the highway, hauls trees and landscaping equipment, etc. Only problem with it: it burns oil like hell. That'* a $20 fix, coming this spring.

I need to add the Mazda rotaries, and the Subaru boxers. I don't know the sizes but they are neat!
