I want to build a motor for my 85. I have a 350 2 piece rear main block. I am trying to decide if I want to build a a 383 or a 355. With the longer throws of the 383 in the 350 block are there any down sides the the 383? I plan to have a qualified machine shop do the block prep either way. Comparing the two will the 383 live as long as the 355 under the same usage? Also is the 383 an engine with more torque than horse power compared to the 355? I will be using the truck as a tow vehicle extra torque would be nice.
