SBF 289/302 Weber CROSSRAM! Is it true?

[Jim Kellogg]

I believe that Sizzler is referring to the photo on post #14 by *13* showing a cross ram on a Blue 289 FIA? Cobra. Looks like adapters on a 2x4 manifold...

Still a nice looking setup.

Not to argue cause' I can't see from the angle of the pic, but how can you tell it's on a 4x2 manifold? Or have you seen it up close?

To put to ease the debate of the manifold shown in post #14 with the dcoe's, it is not a dual quad with adapters. That is one of the very few remaining Mickey Thompson crossram's for the 58mm sidedrafts that has had adapters made to change the flange pattern to run dcoe's. I am 100% certain of this because I own one of the M/T crossram's with a set of 58's.

Thanks for that. Makes more sense to these eyes. That SBF certainly doesn't want to suck on a set of 58's, so the step-down to 40's or so makes sense. Maybe the 40's are OK for the street, but for a racer-X they might be too small, inaddition to my other comments above. Was this intake really for SBF's or are they adapted from the MT SBC manifolds? i have forgotten if MT made them for the SBF and seem to think they didn't.

Those are just beautiful artseyfartsey bits! They are the cat's asymptote. AND they clear the tall rocker boxes nicely. Who, where and how much, if you will?

Never seen the M/T crossram before. It is a nice looking setup!! How was the performance compared to the (more common) IDA carbs and manifold?

Thought it was 2 Cannon?? adapters on a 2x4 manifold with the DCOE almost horizontal in the photo.

I have set up several DCOE carb systems in my shop back in the 70's, all on imports (Triumph, Datsun, ect).

There were also some cross ram 351C injected manifolds used here in the US. They were used on road race cars like Panoz, I thought that Saleen had something to do with them but am not sure, could they be related to that Aussie setup? There may be enough of them floating around to come up for sale some day. The Panoz factory has an engine with it on display in their lobby, true eye candy.
Vintageweber's idea of a crossram intake is a great idea and overdue. Having it clear the distributor is surprising, it's really hard to design a nice induction system that doesn't get in the way of the distributor as seen on that Aussie piece.
