Al, and oldskool, Thank you very much for the input, My car is a four speed, will have 4 wheel power disc the next time it hits the pavement, I'm shooting for july at the lastest. It used to be a 6cyl and I don't know how to tell for sure (car isn't here) but my buddy when I was young said it had a 410 rear, he had the same car as me but his was a 67 coupe. Did they come that low? I know when I had the 389 in it it was a rocket up to 110. My buddy had a 428 in his and ran 12.1 quarter, and spun for 500 feet. Al, you made the camshaft something I understand a little better now! I was leaning to the 41 cam because thats what was in that 428, yes we loved the hard lope, I have a mechanic who says if need be we can add a vacuum pump for the brakes, not sure how but he seems to be confident and he's a GM mechanic, with his own place, very smart and a good friend that is helping me and giving me my own lift in the garage till we are done. going to put a new suspension on a brand new sub, mount the motor and muncie and roll it under, new rear leafs and hotchkis frame connectors and x-brace. It's been 18 years since I drove it, I can't wait. Oldskool, I'm checking out the cams you linked me and diving into research.
