My 72 blazers 350 is tired, very tired...60 over.. In my search for a good 350 block to build I stumbled upon a 71 402 out of a camper special, complete all brackets pulleys, mount towers etc. Guy had it rebuilt now a "408" and ended up needing some cash, the price was half of what I would have put into a 350.. Anyhow.. Questions..

I was converting to 700R with the 350 and rather than messing with drivelines I was just going to move it forward the 2"..

Doing the BBC swap does anyone know how this will effect the location? I have the BBC truck motor mount towers, but have read that the SBC towers work fine. One would assume the BBC swap would just require the 2" move forward just like the 350 but wanted to pick some brains to avoid as many "noseeums" as possible.

Thanks
