Heartbeat is looking to spend $125k on a intake

If Winters made the original castings for the manifolds, that would be the first place to start. They would probably still have the drawings, and the ability to produce the manifold. It might be cost prohibitive though.

Betcha it’s less than $125,000. Ha

Business must be real good at Heartbeat!

Angles are different, but the top looks pretty much the same as the regular cross ram top. I'm sure that the bottom is different, but can't imagine that it would be too difficult to produce a pattern with today's technology. Heck - someone modified the bottom mold to fit the hemi heads 50+ years ago.

Tops are identical as far as the fit and function. If they modified a ‘production’ xram, they only used the top 1/2”.

The differences are drastic other than the top 1/2” where the top plate mounts. The port layout is very similar to a Boss 302. ( I bought an original intake to compare ports ) The rad hose mount comes out the front and not on top. Drastically different.

I asked Jim if I could 3-D scan the intake on the silver car when he owned it. I considered trading some ZL-1 parts for the motor out of that car when Jim offered it to me. But we did not end up making a deal and he ended up buying my parts from me.

There was also an auction in Phila years ago that had a hemi head stup along with an original ZL-1 block if I recall. I was out of the country or I probably would have bought it.

The lower intake does not have a part number. The top plate has a part number for the lower and upper intake

Is it possible there's an extra top so Smokey could use different carbs? Say one setup with 600s and another with 780s? It would make it easier to change than to remove and replace the carbs. Heartbeat may be looking for something that doesn't exist.

Hemi top is interchangeable with all X-rams. Only difference I saw ( besides two part numbers) is the mounting flange for the carbs was larger and most likely stronger. Other than that they seem identical.

I went to that auction in Philadelphia. Bought some NOS parts & bid on the ZL1 block (which was badly damaged). Wish I would have known the significance of the hemi head setup:-(

I remember seeing the silver z at Floyd Garretts museum and that had to be a long time ago. Maybe 20 years ago anyway. I might still have a picture of it
