A while back I heard about someone developing some sort of shim that goes in between the side intake manifold covers. A gain in torque was a result of the shim upgrade due to the increase in air volume in the intake plenum. Do these still exist? Who makes them?

I've heard of the TB spacers (mostly depending on the car thedo nothing), but not Manifold spacers?

Hmmmn... I wonder what would happen if you put longer manifold hoses on an '85-'86? Variable length?

It would act as the S4-up spacer. The small tubes can be replaced with sections of 2" rad hose. The 2 large ones probalby have to be special ordered.

I think about 8mm thick spacers are thickest which will fit before side plates get too close to fuel rails. They should help on stroker top end hp as they allow easier air flow. Will not do much if anything on 5.0L.

Thanks for the replies. All I needed to know!

Don't know if this file will attach. Old-timers may rem. these.

Is that something that allows you to attach a pair of Holly four barrel carbs to the intake?!?

That was the first version of MoPar "Ramcharger" intakes. I believe first used on 383's. It was replaced by a more compact design.
I'm sorry if some thought it was for a 928! You were all excited that an even stranger manifold than the one on '85'/'86's was avail.
The cast iron exhaust on these cars was equally cool - they were rectangular and very intricate. I'm not a MoPar expert (was into Fords in the early 60's), but the castings were fast looking!

I don't know if you've ever ridden in one of these cars, but those manifolds WORKED! Here's the shorter racing version,

Hammer not often you see a nice piece of hardware like that sitting on the carpet inside the house!
Although I did have one friend who had a Snap-On tool box as a piece of furniture, and two Harleys sitting in the sunken well of his family room.

IIRC that manifold was first used on the 426 and the carbs were Carter AFB's.

I thought those were the cross-ram first used on the 413 Wedge... My Mopar lore is fading these days though.

What are the spacers for? Typically its just to keep heat out of the intake isn't it?

i think alex is still working on these..
