Cross-posting is prohibited. Post to one forum and wait for an answer. You'll get the best responses in the computer tuning forum OR in the V-8 engine forum.

yes, b/c god forbid someone actually read your post and respond....

Edelbrock makes a 56mm and a 61mm throttle body. I'd go for the 56mm with your stock engine...

yeah, from what I understand, anything over 56mm requires port matching to fit.

EDIT
Oh wait, I think that's just on the 302's.... somebody confirm.

you are correct. The 61mm (quote from PAW catalog) "requires port matching to fit most manifolds."

56 requires no port matching and is tuned for the 351. Edelbrock no longer sells a 56mm body. I just (last week) put a BBK 56mm throttle body on my 96 sport it was easy and works great.
