There are fellows who use beefed 350's at the drag strip, but it's because they're trying to find a couple of tenths due to the lighter rotating components as compared to a TH400.

Big block, TH400, 9" rear (measure a late 70's Bronco) for cheap, bulletproof fun. 049 or 781 heads from racing junk, ebay, craigslist, etc. Google "049 heads for sale".
Thanks for the simple and straight-forward recipe techninspector1! I'm gonna start pricing shopping on this stuff and report back.

Based on all the feedback from you and the other members, TH400 it is.
