I have no idea what either look like as I am not into racers. I do know the one he has, has a casting number 428-402 on it and it is for a four bolt carb.

So you are saying that a KR with shorter cylinders uses the same intake as a standard K & KH?

Chris,
That casting # will work on the KR. It also fits all WR motors. If my memory serves me all the MR carbs are 4 bolt except the MR2. 'dog

All 1940-65 WLDR, WR, K, KH, KR used the same 4 bolt manifold. Many race manifolds were polished, don't know if it's factory.

Hi All,

Yeah, K, KH, KR, WR, all the same 4 bolts manifold, part# 27020-40...

However, I've seen the majority of them in cast steel but also a few rarer ones cast in brass... Anybody knows where the brass ones come from???

The same length manifold fist both the K and KH barrels despite the 3/8" height difference because the KH ports are longer.

The only difference that I have observed in cast 4-bolt manifolds is that some have indented numbers, while others have raised numbers.

The brass thing is still confusing, although I suspect they must be postwar as the material was too strategic.

OK. a few things here.
First off the brass manifolds are from early 1941.

My friend has two different KR engines torn down right now. The KR has shorter cylinders and different flywheels marked with an R. The other engine, which is a KRTT, has longer cylinders and different heads. Does this make any sence?

He has two cast iron manifolds. Neither polished. One with raised numbers and the other depressed.
So I guess one of these will work on his KR.

Chris, your friend has something unfactory, I do believe. The one with the longer barrels may be a KHRTT, or one someone put together, or he may have a short barrel KR, that we were talking about here a couple of weeks ago. You should measure those barrels, and get the info on here. Then these guys will know exactly what you are dealing with. A KR and a KRTT, should be same barrels.

Panic is right;the brass/bronze intakes are early ('41)WR,all K intakes interchange and are 4 bolt,polished intakes started on the KHK's.Taller cylinders are definitely KH ,no way around that. BREWSKI

I guess the question now is which manifold is correct for a 1956. The raised or depressed 428-402 casting numbers?

I own a WR(brass) intake,several K intakes and even a '68-'69 twin carb intake. Just guessing I would say the stamped #'s are a replacement(over the counter) part as I have never seen one. BREWSKI

So the WR intake manifold is the same as K and KR? All have the 428-402 casting number on them? Which came first. Raised casting numbers or depressed casting numbers? Which is correct for a 1956 KHTT?
