Here is the old engine and the one that will replace it...
The old one is a 305 2bbl
The new one is a '74 350, flat top pistons, vortec heads, performer intake, holley 600, with HEI
Equiped with a new GM serpentine belt accessory setup from SUMMIT!
I plan on using this AC compressor with the factory air... (will burn that bridge when I get to it!)
Notice the TH350 trans... worked great, but would leak if you let the truck set... (gotta decide what to do with that...)
