383 Build up questions...

We did a 383 quite a while ago ran low low 13s in our 67 charger(@3800lbs) and it was stupid simple barely more than a stock rebuild with a cam, had the stock rotating assembly(including the original pistons) balanced with good rod bolts, edelbrock torker cam(prob go with something a little more modern(I just built a 383 with the 268 xtreme energy cam and it sounds pretty good)torker intake and a worked thermoquad, super comps,3k stall,full manual vb and 3.91s. We had stock size valves with a little cleanup work and a really good valve job. We put tons of passes on that engine and it never missed a beat we ran it for yrs ended up selling it to a friend of ours and he put dual quads on it and put it in a 57 fury he built for his grandfather and its still running well.
Good luck,
Jr.
