The E4OD is a pretty good tranny, I think people rebuild them with parts from later years because of the fact they were way better after something like 1992. They used them for Powerstrokes, they are tough transmissions.
Keep it simple! stick w/ a moderate/sensible build on the 302 HO. The 351's a dog comparatively, although it's hard to replace displacement. Depends on what you want it to do well when your done w/ it. Pull a trailer, or dart through traffic?
It's a common mistake for people to build an engine that ends up not coming alive till knocking on the door of 3k rpm. Makes for a sh!tty, problematic daily driver!
The word "Rebuilt" when describing a transmission put's the fear of God in me! Never done well w/ em. That's why I Transtuned my 87' & switched to synthetic tranny fluid as soon as I got my 87'. Owner servicing negligence is by far the #1 transmission killer.
I suppose if you find an obsessively perfectionistic SOB that really knows his ****, you may fair ok w/ a rebuilt tranny. Good luck w/ finding one! Most Tranny shops have a "good enough" additude, & that does not translate into longevity!
Personally (w/ the 11+ Ford's I've owned), rebuilt transmissions have worked out the best for me in the past, when I sell the truck immediately afterwards, using the "fresh rebuild" as a selling point! Some people actually like seeing that in a prospective used truck purchase. Go figure!
Pushin those meats you have on there probably don't help! They're better suited for a manual shift. Those weren't figured into the equation when your transmission was being designed!
