This intake is kind of the "missing link". It is the only single 4bbl intake that I know of that works with stock Max Wedge heads on a RB block. It has a built in valley tray so you don't need a Max Wedge bathtub intake which doesn't exist.

It is a low profile intake that is 1.250 inches shorter than a Super Victor or 440-2 intake.

The 337 intake will also fit on Indy or Victor heads but you'll have a double air gap. This might be a good solution for someone who wants to run the Indy heads under a stock hood since the low profile might just fit.

So, your saying it will fit over this Indy plate with EZ heads. Will it hit the screws in the Indy plate? Also, how does the height compare to a Eddy RPM Performer intake.

I don't think that's what he's saying at all... nor do I believe it will.

Looks to me from his picture that it's setting over a plate. Not sure about the screws. Might have to use a button head type.

Yeah, I took another look... it's shown setting over an AR Engineering plate, not an ICH plate. Not sure how they compare. I'd think you'd need to run the ICH spacers like they offer for EZ and SR heads to use the standard valley tray and rely on the built-in tray on that intake to seal off the valley. Maybe it's less of a hack than it sounds like, but it seems to me like more possible sources for oil leaks.

There is about 3/8 of an inch air gap between the bottom of the 337 intake and the top of the valley plate. I used button head screws and everything cleared just fine. Hex headed bolts might clear, allen heads probably wouldn't clear.

I believe the 337 intake is lower than a Performer RPM but I didn't check that one. They don't really compare since the RPM is a standard port intake and the 337 is a Max Wedge intake.

The 337 obviously isn't designed to work with the Indy or Victor heads since the double valley tray is just a waste, but it might be a back door method of getting a Max Wedge intake under a flat hood. How well it performs is an open question at the moment.

That would be another way to do it. Use the 1/2 inch thick end rails to seal off the valley ends and skip the lower valley tray.

If I was going to do that then I'd probably drill the 337 valley tray for bolt holes so I could screw the whole assembly together. That would cut down on the leaks. Or, hold the end rails down with flathead bolts and then just use RTV on top. That would work also and maybe be a little easier to R&R.

Maybe I'll fabricate a set of end rail spacers to illustrate that idea.

I just saw a buddy of mine had one of those and we both commented on the lack of fitment and finished quality. I didn't get into it ,but he was showing me how the bolt holes were wayyy off. You could almost put 2 bolts in each hole. and the 1/2 inch gap at the bottom......His was on stage 6 heads, so I assumed it was just standard mopar quality...

this intake is not for stage 6 heads or raised runner indy's right?

this intake is for stock, max wedge or rpm heads ported to max wedge size, correct?

i thinks its a great option if i have that straight

Fit and finish on the one I have looks fine to me. Bolt holes lined up perfectly with the Indy heads. I don't have a set of original Max Wedge heads or I'd try it with them.

Only thing I don't understand on this intake is the four big spuds that sit on the intake runners. I'm guessing someone put them there so you can bolt on a hood scoop or an air pan?? Beats the heck out of me what they are for. Maybe Zippy knows?

Correct. This would be the way to mount a single 4bbl intake to either stock Max Wedge heads or RPM heads that were ported to MW size. It is the only way that I know of to do that trick with an OOTB intake manifold.

Could be I guess. Not sure why they did that since MP has never shown any interest in providing a retrofit EFI kit for big blocks though. Maybe some engineer had an idea about EFI but it got shut down before any progress was made?

Here is a view from the front. I think this shows the double valley tray a little better. It would be hard to make some spacers that fit into the ends since they would have to have V shaped notches to mate with the Indy heads.

I think the spacer trick would work with Victor heads though since they have a vertical surface facing the valley area. I'll mock it up with the Victor heads just to see how it looks.

Hmmmm... if that's the intake I had to run w/ that combination, I'd start looking at the easiest way to off the built-in valley cover and just run the ICH / AR Engineering plate under what's left of the intake.

Andy, could you put a straight edge across the carb. flange over to the valve cover and measure the carb. flange height in relation to the top of the valve covers since I'm using the EZ heads with those valve covers I could tell how much I have to play with.

I wonder if there's enough meat in the casting (before the carb pad is cut) to make a 4500 version

Agree w/above, looks like FI capability was design intent, but that's not from any notes from a print or anything like that.

I'd expect so, considering MP did the same "trick" (ummmm... hack?) to the Stage VI RB intake that's similar in design.
