383 knowledge anyone?

First off lets find out what you got. Do you know, for sure, what year the block is. If not behind the distributor is a 1 1/2" square flat spot on the block that will be stamped with a letter then 383. Also, have you got heads and if so what are casting numbers on top of the heads. Then most importantly how much are you prepared to spend since the 383 stock was 330-335 HP and could go to around 450 HP with stock (forged) bottom end. Keep in mind that the heads, rocker arm assembly, camshaft are shared with the 440's. Try this article for starters www.moparmusclemagazine.com/techarticles/155_0209_resto/
