Crossram, was there ever a single carb adapter plate?

[KurtS]

He added the hood, it is not original.

WOW!  That book got EXPENSIVE!  Bought mine for $18.

I see now I wasn't clear. Warren collected the rarest of the rare when it came to 69 Camaro parts. When he became ill Chris White helped him get the car back up and running after he had parked it in the 80's. He added some of the rare parts like that hood, air cleaner, adapter plate, prop rod etc.

Thanks Kurt.

Just tell us what that book said. I can’t find mine at the moment.

my Question was "is there or was there ever a single carb adapter for the winters crossram?", but I may not have been clear enough.
I'd like to know it there was a single carb adapter plate to fit on the the winters crossram to change over from duals to a single.

There was no single-carb adapter. The purpose of the cross-ram was to increase [1,200 cfm] fuel-flow over the production 780 cfm carb. There is no reason to believe Chevrolet Engineering even considered it; the SB hemi-head was a clear failure but is listed in the SCCA/FIA homologation documents. A single-carb adapter is not.

That is correct. For 1970, a single 4V carb was 'required' for SCCA Trans Am racing. So, as I believe Chevrolet went back to a single four intake. I'm sure Jon (and others) will chime in to educate us what exact intake was used for 1970. As a side note, the Brand X models had the options of either a 4V, or an 8V tops for competition use.

would an Offenhauser #5901 single quad top fit and work on a Winters Cross Ram base

[MO]

Man, I imagine only someone that tried that would know. Is the bolt pattern similar at all? Next question: why? If you have a crossram, why would you want to run 1x4 on that manifold? Why not just install a single 4bbl manifold that will work properly?

just thinking outside the box, just curious

You could just fabricate your own alum top. Very simple to do. OR, you can have a machine shop make one up for you. That said, it might be easier and cheaper to purchase an aftermarket single 4V version like an Offy, or Smokey Ram intake instead.

The manifold tops are very close, the largest difference being the Offenhauser bolts are 1/4", the Winters intake top is drilled for 5/16" bolts. I still have a couple of Offenhauser gaskets to check with, but unfortunately no Winters to match them up with (sold all of my Offenhausers, had two single four tops at one point in time). That would be the easiest way to check -

Ok I found my book. The 1x4 adapter plate they are talking about is for the HOOD, not the intake.

I stand by my original response to the initial post.

[169INDY]

^Correct, the conversation shifted to the Hood. & the Book contains Nothing related to a ALum single 4BBL lid for the Xram lower intake.
