383 knowledge anyone?

?? Now it's not a 383 anymore, right? So the head requirements from your other post changed too? I still wouldnt run SREZs(angled plug) or Victors. I'd run the MP Edelbrocks with one of Jeff at Modern's programs if he has one for them yet.

Lose the hydraulic roller if you're running Schubecks. Run a solid roller profile.

The carb is too small. look for a modified HP, or a Dominator 1050.

my .02 here...Looking at the crank and oiling system..To run the 4.15 and chrysler rod you will need to clearance the oil pickup boss. If you go to the heim pickup, you make the area weaker still. I would use the 440Source crank with Chevy journals. It's a drop in, and he has a nice rod for the $$ to match it with the chrysler width. And dont forget to radius the 90° turn in the oil's path in the block. I'd also make sure the valley area is deburred and the return holes smoothed out.

For 8000 rpm and a decent roller, buy the best rockers you can once. (T&D would be a good choice) Or you'll be buying Crane golds over and over as they break.

The intake, I'd run the Victor...
