My guess is you would be quite disapointed from a performance perspective. As mentioned in the other thread, you need torque to move a 35' boat, and a small block gas engine is not going to cut it. She will be underpowered (by a lot).
If I could guess again, that block (340) probably produces between 250-300 ft/lbs of torque (too lazy to look it up). Now, someone should chime in and add the torque numbers for a 5.9 Cummins, for example.

Major brain cramp on my part. When I read 340 I was thinking cubic inches, not hp. The car guy in me thought Mopar small block. Ok, so we are talking gas, 340hp/385 ft. lbs. torque. Still underpowered.
