SBC manifold measurement request
May I ask of someone to give me the front and rear height measurements of an intake manifold for a '73 SBC L48 so I can compare to the Edelbrock and Weiand manifolds? (Measured with a straightedge on the carb deck.) I just can't seem to get accurate enough with it on the car & running. Thanks,
John

I've already done the work for you ... accurately too ... you owe me a case of beer ... 3973460 OE on 1971 L-48 C3.
Intake Manifold, Cast Iron c/n 3973460 F = 2.69”, R = 4.375”
35 degrees down in front
Intake Manifold, Weiand alum. p/n 8004 F = 3.50”, R = 4”
11 degrees down in front
Intake Manifold, Edelbrock alum p/n 2101 F = 3.50” , R = 4.60
22 degrees down in front
