The 433 that I'd put these on already have 18cc dished to get 9.8 with the 72cc 48's
I'd have to go with 65cc chambers or get new flat top pistons and around 75cc to get me around 10.5 with the new heads.
Personally I'd prefer the FT piston and 75, but there's another $500+ piston adder to the bill, for street use the dish would probably be ok.

Now the question is, will the 72 chamber already be in it and can I mill it down to 65, or have chamber profiles for smaller to larger, and made to order?

Just got an estimate on a quad intake.

4500 to 6500 complete finish like it was a factory piece. My ass hurts.

Take the pain out of your ass and make it yourself.

I think that comment is easier said then done. Once you put a bead on the intake it warps like crazy. It's a constant battle to keep the flanges straight as you massage the part into position. I have done sheet metal welding but never aluminum. I don't think I want to learn on this project.

Thanks to others that verified the deck height on the V block.

I guess my homemade hemi blower manifold could be called "sheet metal"; 3/8" aluminum sides/front/rear with 1/2" top and 1/4" bottom. Total cost was very low- I machined and formed the pieces and paid a local shop (not a race shop) to TIG it together. I provided him with a bare long block to use as a "jig". I only had to do minor milling of the flange and top surfaces after it was completed. I probably paid more to have it professionally polished than it cost to fabricate!

Hey Jack -

Yeah, a sheet metal intake is far easier to build then modifying a cast aluminum intake is what I understand, and it makes sense. I on the other hand am going for the vintage retro look and having a bunch of sharp angled pieces with raw welding beads at all the joints is not what I'm looking for.

So with that said, I gave the authorization today to move forward with the low rise dual quad intake. I will request pictures throughout the entire project and post them in the forum so everyone can see the progress in another thread out of respect for Don's project. It's already an all over the place topic, but a very interesting and informative mess we have here~!

... at that price range ($6500), have you considered having one made from 6061 Billet and would it be ok if it were a 2 piece design, like down the middle, front to back ??? ...

... and for a bit more money, we could probably make one for you out of an extremely high grade plastic that i have sourced for this purpose, but this material is very exspensive, but extremely lightweight, which obviously would not look factory ...

... so if a single plane 2 piece billet aluminum style manifold is something you might like, give us a call at the shop and ask for Bill, we'd be happy to help you with your project ... (931-459-2760)"Mondello Racing Engines"

... and if the machining marks are something that would concern you, we can needle-scale the surface, and high pressure blast it afterwards, then we can paint it any color you like, then it will look very close to a cast type surface, we could also design a tapered/flange with a counter-sunk bolt, which would help hide the flange, but not completely ...

... now, if there were enough people to generate a "Pre-Order" list, then we could work on the price, as there would be a significant amount of CAD design for a piece like this, a preorder list would be able to spread the CAD costs over a certain amount of manifolds, lowering the price, depending on how many manifolds got pre-ordered ??? ...

... i would need a set of Don's bare castings just for "Reverse-Engineering" purposes, they would be returned as soon as that was completed ...

* CNC machined 72cc and 85cc heart shaped combustion chambers for on the shelf
heads
* Heads will be cast without combustion chambers so custom combustion chambers
can be ordered to customers spec's
