NA Block question.

[MrRed]

so I eventually want too build up a 3.8 but I have a question. years ago I bought a carbed turbo 3.8. I still think I have access too the block but nothing else, would this be a good foundation to throw fuel injected goodies on? or is it even possible? not looking to build a monster here. I think the shortblock is complete. I searched but it seems 84 is as old as I can find. I'm thinking the engine was from a 79 monte carlo

Any of the Buick V6 blocks from 78 up can be used. The differences are a slight deck height difference and revised oiling. You can drill the oil return line hole at the front of the block, or change it to the pan.

ok thanks, I was just wondering about the internals being possibly stronger compared to a non turbo unit. wasn't sure if the carbed models were stronger or not back then.

I believe that blocks built prior to 1982 do not have a notch ground in the main oil passage for rod bolt clearance if you are using 2 dot rods. The stock rods do not have a problem. I remember building a 1980 block with 2 dot GN rods and ARP bolts, and the rod bolt from # 1 cylinder hit the block. I had to grind a notch. Am I correct Charlief1?

Kinda strange. Never had that issue myself but there are variations in the blocks where I could see it happening. All the blocks I've delt with and have now, I've never seen it.
