That’s sexy!! Lol
Is the blowers location in the same spot as your current manifold?
So the snout lines up with your crank pulley.

It will sit the blower back about an eighth of an inch compared to the Offenhauser based old manifold. When I have an engine on the stand I will mock it all up.

I'm very satisfied with the manifold. I also discovered a place 75 miles south of me that rebuilds roots superchargers. I had DMPE inspect and go thru my 144. It was in excellent condition. They cut the rotors and added Teflon strips. All bearings were replaced with US made bearings and seals were replaced. This blower is better than new. Its all very expensive! This will be an engine I plan to enjoy for as long as I can. In my boomer years I don't want to be the quickest but I want a torquey punchy fun vehicle that is STONE COLD RELIABLE.

Never mind the port sizes here. What's important is the new manifold on the bottom has sufficient sealing material around the ports. The top unit is the Offenhauser 273 manifold conversion. The Offenhauser works on 340/360 heads but one must pay attention when installing on 340/360 heads to get a proper seal.

Here’s a B&M 144/162 manifold.

Post a pic of the top of your old manifold, I’m assuming it’s a dick landy unit

That’s too nice to be a dick landy piece!

I will be selling the Offy based unit.
