65 valiant small block turbo build

Hello everyone, I'm working on collecting parts to start a turbo build this winter. I was wondering if you guys can tell me options I've got to control the timing on this thing. I'm looking to start with a budget turbo build to see how far I can take it on a stock motor. I will then build a turbo motor to take a little more abuse after I get my feet wet and have an idea the to do's and not to do's on this low dollar build. I was looking for a recommendation on who to contact about a custom grind cam I have tried bullet twice and they are not getting back to me. Any other people you all recommend? I'm looking at a blow through bare bones set up. I do like the idea of pulling timing under boost but was curious if there are any other options out there.
