Can you I.D. this 6 cylinder intake? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

BLAZERMAN · 12-05-2006, 11:42 PM

I need help identifying a 6 cylinder intake I have, cant find any numbers or brand name. Its suppose to fit chevy 250 and 292 but it has 2 more bolt holes tha the Offy does in the back ground.

It's a Clifford. That's an interesting hi-rise intake on the Offy! Any info on that would be appreciated.

Thanks Brad, I have seen some Clifford intakes before and they were always marked, thats what trew me off on this one. I dont know much about the Offy with the cross ram adapter, got this in a bunch of hypo 6 cylinder parts from an old timer that use to race around here.

OOOOOOHHH, now it makes sense. I thought it was an oddball, 1 off Offy part for I6's, but now I see that it's 1/2 of a V8 crossram manifold.

Do you mean a V8 Hybrid head ? 2 V8 heads cut down by one cylinder each and welded together to make the flow-thru L6 head?

those arent BOLT holes. that's where the pins on the ends fit to hold it in alignment.
Clifford dual carb manifold.

Those guide pins come out CCW with a vicegrips. Then you can install 3" studs--3/8-16 UNC into the head + 3/8-24 fine threads to the manifold or headers. Guide pins are OK for stock manifolds but studs and locknuts work better with headers.
As for the intake, it must be an early Clifford Research part, before they changed their name.

We were discussing the Offy hi-rise part. It appears it's 1 of 2 that appear on a V8 cross-ram manifold and someone put it on an Offy I6 manifold for some reason.

OK. I see it now. That is an interesting configuration. Was he moving the carb away from a power brake booster, or up-and-forward to make tuning easier, or for some wierd circle track or midget set-up? We'll never know.
