... the intake we are talking about was designed for the Stage VI head to fit on an RB block so no spacers would be neccessary. Its the one used on their crate engines...



I don't recall the P/N, but that's one of the intakes I tested on my Stage VI-headed 440. Out of the box that particular intake SUCKS.

Mine ended up w/ a LOT of work on it by Roger Helgesen, a.k.a. "Dr. Air". Although the modified version made good top end, IMO it was too big in the plenum and had too much runner taper for a street/strip 440 application. Streetwize bought it from me, but IIRC ended up selling to somebody else w/o ever having tried it.

Brad,

Don't think yours was the same one....yours was a 906 port for an RB with STAGE VI which (if you think about it) will only work on that combo.

I sold it to a guy in Canada who is looking for exactly that....remember any othe RB/Stage VI manifold would need spacers to makethe manifold fit.....what i think is that the 337 will bolt on a non raised port MW without spacers and should therefore (trying to confirm it will) fit on a B with Stage VI's.

Guys, i just re-read the thread on the 337. Altho, very similar, these are two differnt manifolds. Evidently, the 337 is just for non raised port heads like the Eddy RPM(w/MW openings) and the cast iron MW heads.

This is for RB blocks...still dont know what low deck applications it would work on.

MP does not have a low deck version of the 337.

The 337 would would Stage VI heads on a low deck block but you would have to fabricate some spacers for the ends of the valley area.

The 337 is the intake to use if you're running original type Max Wedge heads on an RB block. It works perfect in that application by sealing off the valley area. It can also be used with Indy heads and Victor heads but you end up with end gaps that need to be sealed somehow.

Thanks, Andy!

Yeah looks like an indy plate underneath to seal the valley might work...If it's anything like the RB stage VI some radius work at the carb plate plenum transition would really wake it up.

What's the full part # of the 337 BTW???

So, unless I'm missing something the 337 should also bolt right up on a low deck B motor with Stage VI MW ports????




Bobby,

Bolting up is no problem, but it really wasn't made for that application. Like Andy says, the real purpose of that intake is OEM type MW heads on an RB block....anything else and some areas will need rework.

1. I'd expect more port mismatch than normal because a Stage VI MW port is not a true OEM MW dimension....it's slightly shorter... Andy and I went through that awhile back with MP (supposedly) MW intake gaskets, that really weren't true OE MW dimensions..but they were the right dimensions for a Stage VI max wedge! So that area will need to be looked at closer than usual and worked accordingly. Or if the heads have already been opened up to OE MW size, then they're good.

2. The valley situation may need to be looked at and corrected? But on the surface it seems like it would probably work, unless I am missing something too.

I'm thinking this might be a good intake for the 440 Source heads w/MW openings.

Exactly. It is the only thing that would fit 440Source heads that have been ported to MW openings that won't look like a clogged up mess. We just had an engine on the dyno the other day with original MW heads, an Indy intake and a homebuilt valley pan. As soon as the motor started to make some power the oil started to spray out of the pos valley tray. I think I talked that guy into buying a 337 intake so his race car wouldn't be dripping oil after every pass.
