Congrats on what you're doing here :thumbrig:.
I did several engine like this for me and others when I was a kid back in the 70's. Looking back, I think I had more fun with builds like this then many of the "serious" cars I put together.
With all the stroker's and big HP numbers thrown around these days, many of us forget how much fun a "net" 275/300hp car could be on the street.....especially a light 4spd model :).
I suspect a 71' 318 4spd car came with a 8 3/4" 3.23 rear. If so, that's icing on the cake?
As I always say, be safe & have fun. :D
