A 700r4 and a 3.08 differential is another option.

What would be the reason for reconstructing a 305E instead or installing GM: 5.3 V8 @ 21 MPG highway...or other modern motor. Lots of good used motors out there if you want a restomod style GMC.

Maybe this is just a "what if" post. Not sure. This kind of talk on 6066Club is messing with Mother Nature and Father Time.

Hmm yeah makes sense.... I don't have a $8000 budget either... But an overdrive is a good idea. If you can achieve 1600 RPMs at cruising speeds you're taking advantage of the engine.

Hey a guy needs something to fantasize about...
