Need BBC Intake Port Dimensions

[calereeves]

I'm trying work up some cad drawings of a custom BBC intake manifold, but so far I haven't been able ot find a drawing, or even just some information on port dimensions, and location on the head. Is there anyplace on the internet that has a detail drawing of the intake ports on a rectangle port BBC head?

I'm off at school right now and can't just go out and measure it, but I guess if nothing else, I'll just have to wait until Christmas break to actually measure for myself.


Thanks,
Cale
