Hey all thanks for the responses and questions. I am using a 455 pontiac and turbo 400 along with the usual ford 9 inch. I had bought the frame as a demo frame from a frame building co. in Missouri.In the back There was a parallel 4 bar on one side and triangulated 4 bar on the other. In the front a 4 bar on one side and hairpin on the other. It was used to show what the company could do. I changed things around to hairpins in front and triangulated 4 bars in back. Got the big Pontiac mounted and ran the exhaust now the hard part of mating the hood to the body and grille shell and getting the gaps straight. Naturally I have torn my shoulder up so it will have to wait until I heal. Thanks Larry
