I'm a big fan of bone stock big cubic inch engines and the right gearing (usually in the 2's) for a resto rod. Trouble free, last forever, smooth as a babies butt, and smoke the tires till the next shift. Have used the 455 Olds/Pontiac/Buick engines plus the 472-500 Cadillac in everything from 30's coupes to early 70's pickups, all with good results. TCI is making a dummy proof (fortunately for me) constant pressure valve body for the overdrive automatics that does away with the very touchy TV cable adjustment. Since the bands/clutches are always at full pressure the only thing the TV cable is used for is to set shift points. Just a mere $337 delivers it to your door. As to engine physical size here is a 500 Cad in a 51 GMC and yes the chain steering has been trouble free for well over 200k miles.
