What kind of work needs to be done to a 350 to get it to survive with a big turbo. I have a 76 350 that I would use and I also have a big turbo from back when my father used to pull tractors. I think it is something like 4 inche compressor inlet but I also have smaller ones. It has the #8 heads but I was thinking of doing an at-home port job but other than that I really don't know how tough these engines are. I also have a few other motors I could build (66 425, 68 430, and 71 455 buick) if the 350 is a really poor choice. I guess to sum it up I just want to know if turboing any of these is worth the time and money.

Thanks, Owen

The cast pistons, so so rods and light weight crank are all the possible proverbial pin in the genrade.
