Small block or big block in a truck?

Well, like you, I have zero experience with big blocks. And for that very reason, I plan to install a 383 in my D-100 stepside. One variation though, I plan to use the new 8hp70 or 8hp90 8 speed automatic behind the big block. Efi tunnel ram would be really freaking cool too but this is suppose to be a lot more of a “budget” build than my Duster is!
