W2 Intake

I have St/Dom & the M1. The street version has a slightly narrower port in the plenum and is a clove red square flanged for the carb. The M1 has a wide open square for the carb. Both are water heated.

You would want a warmer plenum for the street. But it will some power in exchange for drivability. It’s a marginal difference. But there. The intake can be easily modified.
