Missed this earlier...
Block is the original 402 ( truck was a BB/TH400 model ) has a Thumper roller cam n lifters. Iron heads, bored n torque plate honed to a 409. Checked & rebalanced crank, replaced everything else. Its not a powerhouse by modern standards but Im not the boy racer type so 418/438 @ 5900 is good for now. It sounds amazing too.
Trans is a 5 speed TKO model. ( 2.87 first, 1.89 second, 1.28 third, 1.0 forth, .64 fifth.
Even with 373 rear gears the .64 fifth gear is pretty tall. Its great for going from town to town but I dont use it much. I also switched to a 4.11 rear so might be a better fit.
