M1 Air-Gap Intake Manifold for a 340 motor

The only two intake part numbers that you need look for is:

P4452891: has the water outlet in the center with angled bypass outlet like all LA intakes. Bolts right on.

P4532851: has the smaller water outlet offset and the bypass outlet is parallel (points straight forward)
Will bolt right on an LA, the original bypass hose takes a little contorting to get it to fit the outlet stub, no big deal. It fits.

I thought we all explained this to you last year? Not sure why confusion remains?

I’d quit digging and focus on the two part numbers mentioned above only. Confusion ends.:thumbsup:
Wow, you're right. My apologies, must be a senior moment.
