Not sure on EFI or Carb. While im saving some money I'll have to think which route I want to go. The original plan was a twin turbo 408 stroker. Carb would be cheaper, but harder to tune with the tt setup. I've never turbo'd or twin'd a carburated car before, but I've heard it sucks big time. I think i'm leaning a little more towared the carburated setup. Good news is I'll get some experience with the carbd setup. I've done 4 turbo setups & 1 twin setup successfully (no v8's). Hopefully the 351 goes as well.
