Can you get a plenum spacer from them, or do you need one? Seems all the pics of them, I see one sandwiched in there....And what size carbs for a 512 reving to 6500? You can buy them from Indy or make one obviously. There was at least 2 diff bolt patterns for the lids. What do you need? That's a question for the person who is engineering the entire engine from carbs to the oil pan. There are many ways to skin a cat and you have some core pieces to make power but the devil is in the details. Hutch, over at the bullet, mentioned one time that two different guys can build a 727 and one will be over a tenth quicker than the other while USING THE SAME PARTS. The engines that make more power than average ones likely have some more engineering incorporated. How different are the bolt patterns? I've got to make a new top for a friend's Hemi intake, I made one for a Wedge intake many years ago, I was hoping the bolt pattern was the same.

It is totally different. The old style uses a pile of flat headed, counter sunk #10 machine screws. The new style uses 14ish 1/4" or 5/16" bolts (cap screws) if I am remembering correctly.

Sorry missed this...I dont have a new one to see the differences and if there are MANY changes thru the years??? It seemed to me that the 3 i have worked-with being different in that the newer series has fewer perimeter anchor screws. For what it's worth i didnt use the countersunk fasteners. I used a large washer to cover the 'relief' and then used allen bolts. ALSO only used rtv...NO paper gasket material on the lid.

In reviewing this thread i noticed there is a small grease finger print mark on the driver's side VC above the filler port! Good eye. But it's a chip that was touched up when it blew the top of the manifold off 10 years ago. Landed upside down caught by the throttle cable and fuel feed line. That was before it caught on fire. Same paint from 2012. Doug

The top on the Hemi intake i've here in the shop is longer than the top I did for a Wedge intake about 10 years ago. Once I have modified the CAD, I'll try to remember to post a drawing of both. What linkages do people tend to use? This engine is running two 4500 type throttle bodies, so I might be able to run the linkage in line?

I don't know why people don't do the linkage like what is pictured by DVW on his INDY C/R. It eliminates an inefficient mechanical coupling. If i ever redo mine again, it'll be this same way. (except maybe not use a dollar-store cable.) Looking forward to seeing your drawing...you do nice work. "IF I WERE INDY"...because it was released later, I'd also have designed the modman top so it was interchangeable to the T/R, the carb placement could be the same/ideal.
