Carb and efi?

[NorCalTurbos]

Quick one maybe dumb but I wanted to know if there are any differences in the block or heads on a carb motor as to efi besides the obvious?

blocks and heads are plain ole buick dimensions. nothing EFI specific about them

Thanks, I did notice the 83 block doesn't have the hole for the knock sensor drilled out, I'm gonna drill and tap it myself

It'll also have a 14 bolt pan, and have to turbo oil drain hole.... but for the most part the architecture is the same.

Thanks bro my buddy seems to think mines runs better than his he thought the heads,cam or crank might be different

The tune makes 1000X the difference of hard parts. Having a turbo takes so much stuff off the table that N/A engines have to worry about.
