I took your advice and have two 4500 manifold to 4150 carb HVH adapters coming.

What are you guys using to seal the top to the base on this intake? Hylomar? Should I get a sheet from Superformance and make a gasket?

Thanks for answering all of my dumb questions. Tunnel rams are new to me as you can see.

We are going to back this engine up with a Lenco ST1200 so it should be a fun car to drive. Hard work and even harder play!
