Hey all, kind of dumb question. I bought a empi 40 HPMX dual carb kit with the hex bar linkage. I got it all assembled and the damn thing doesn't sit right. the receiver sockets for the ball ends are off set to compensate for the cylinders being offset, but it doesn't look like they are offset enough. Any tips?

also, the case is a universal type case. if that makes a difference.

Pretty sure they have a set for straight intakes and another for offset intakes. You might have the wrong one?

Looks like straight manifolds and offset linkage.

Yeah, I think you are right there. it is pretty awesome this came as a kit. Smile Got to love Empi. I think I will eventually do the sync link, so I just made it work by clearancing the bushing a little.

I made a plate to adapt mine when I put a new set of heads and manifolds on my motor. Turned out spot on.

Nothing like having to "make" a purchased part work correctly.

True, but the linkage was already on the car for over 3 decades. And no sense in having to buy new carb mounts for them and I had no idea what i had or what to ask about when ordering heads and port matched manifolds.
And the SS I used is plenty stiff and looks decent.

And besides, if you didn't have to make/modify anything, all you did was assemble parts, not "build" it.

I like what you did there. Maybe I will do something like that. Also is that distributor stock? Looks a lot like a electronic ignition in a distributor package.

It is a modified HEI distributor, my father did that before they came out with the kits and write-ups on how to do it, way back when.

just get the correct bracket and all will be fine. if you bought it new empi should send you what you need free,well they always sent me what was rong in the empi stuff Ive bought.Ive never had any service issue with empi. witch is why I was so happy when they bought bugpoop, as bugpoop had zero service.. it wood of beeen nice if they had made those brackets with adjustable stanchion for the bar to be adjusted up down fore&aft....then 1 part wood cover mulitable situations. nice doubble stack filters!!!^^^

Thanks, I wanted more room above the stacks and this added enough and just fit under lid with no modding.

My personal opinion is to throw all the EMPI and CB hex bar crap in the trash and get the CSP bellcrank linkage.

I ran my empi li kage like that for almost 2 years with no problems. Ended up wearing out the heims on the down rods and went with cb linkage with cast bases and tops.

I had exactly the same problem. I had to stick to my guns and press Empi. At their request, I sent them all of the parts that came in the kit I bought and they mocked it up and saw it wasn't right. At that point they scrounged up a different linkage plate and now my crossbar is parallel with the fan shroud. For the inconvenience they sent me the upgraded bearing assembly for the ends of the crossbar as well. You may want to try to see if they will send you the correct plate.

I have the contact number for the guy I dealt with at Empi. If you want it send me a PM and I'll share it with you. It may help using the same guy as he realized there was a real issue in the end and made it right.

Edit: I just pulled up the picture of mine and it was the opposite angle from yours

Empi crossbar kits dont fit redline air cleaner bases without running into this problem. Same thing with CB crossbar kit. I have to mod them when I use those with red line. The offset manifolds dont compensate enough for the early redline filter bases which I like to use on air box setups. It is the early redline bases that cause the issue from what CB said.

That is a possibility in certain cases, but all of my parts including the manifolds were supplied by Empi. It appears from the OP's first post that he had all Empi parts as well. It is certainly a quality control issue with Empi matching the manifolds with the lower air cleaner bases.
