It was 75 deg hear today in east TN, got me to thinking bout spring? When all winter chores, Firewood and trips to store in snow, are done I'm going to start my 3.7 boat engine install. Before I lay down $$$ for t90 adapters, I was thinking what other options I might have? I might could find a 3 or 4 speed tranny that would bolt go my GM bell without an adapter? I've read novac and advance web sites, BUT I'm still confused as he%&. What other trans are useable, relatively easy go find and don't cost an arm and a leg, that will allow me to use the Dana 18? All comments, and recommendations welcome! I know 0 about these conversions? It would be great to install a tranny that cost less, or same as the adapter. I want to keep the off center diffs and Dana 18.I did notice the 18 was adaptable to several different tranny! Let's hear some,(What would you do commets). Remember the new engine makes bout 200HP, and 300TQ. I'm not hard on equipment, but would like it reliable ,and bulletproof to all but a teenager? LOL PS I have some connections with a 60s,70s, chevy classic truck restore shop, that junks several straight shifts, in favor of autos, he says they sell better witbout a clutch!
