I want to build a wedge. I have a B and an RB block to start with. I'm not sure which one I want to build so I guess I'll just start trying to round up some parts and whichever one I find the parts for, I'll go with that one. I like the 337 intake for the 440 and I would like a 4500 M1 for a low block. If you can help me out with these let me know, thanks.
