Hello Guys.
I figure we might as well make this official, as I'm probably picking up a 1 piece RMS block this Monday. I will be sending to machine shop and getting proper work done to put a 383 Rotating Assembly into.
It is a 638 casting with provisions already for the Dog Bone and front cam holder in there. It has 4 bolt caps, but a little surface rust. I'm going to throw down $150 for it if it looks decent when I get there.
I have been scouting around here for awhile and there's not much to choose from for building a factory roller motor. Been seeing a few 400 blocks which would be ideal, but one has been punched .06 already, and the other needs machine work still and they want $500 for it. Not to mention the added cost of Retro Cam and Lifters. Also there's another that needs a sleeve, so I have decided just to go for a 383.
I am already putting together the 200cc intake runner heads right now, and am hoping to get this thing together rather quickly.
