360 or 383?

Offer $350 for the 383 and stick it under the bench. Parts, machine work, and miscellaneous will add up to an easy $2500 done right. Your time or someone else's for labor.....there is your cost estimate for BB. Oh, I forgot to mention all the mods required to not only fit the BB under the hood, but make the car run right as a package. Unless your goal is smokey burnouts.

Small block in my opinion....but don't tell my buddy that, he is always muttering there is no replacement for displacement...or cubes..or some nonsense.
