I went on mancinis web site and wasn't sure which manifold it was, could some one give me a part number for this intake.Is this intake a MW already or do you have to port match it
Thanks
Kevin

Im not sure that Mancini carries it. I emailed them about a week ago and it didnt seem like they had them there but they were willing to find it for me! Good luck.

542,

As delivered the '337 leaves the ports very much on the small side compared to a true Max; they're more like dead 1/2 way between a standard 906 and a 2.6" x 1.3" Maxie, this may be so it could be possible to use the 337 on an 'oversized' 906.

I've actually ported several Holley street dominators with larger port windows than the 337 comes OOTB. I wasn't exactly pleased to see how much work they would take to port match my Max Wedge heads. What they do have is a very generous port entry from the plenum with good taper, I was pleased with that considering to look at it visually and it's low carb height....at first glance and it pictures it didn't "look" like much.

I just had a set of Trick Flows opened up to match a 337 manifold,the ports polished, along with some flow numbers.



The work was done by Larry Smith of Flow Tech 2 Cylinder Heads. I can't say enough good about Larry, he is a pro and a great guy to deal with.

Trick flow heads, ported 246 cc runners

My motor is a 528 CI RB bock 10.1-1 with this cam

https://www.summitracing.com/parts/hrs-720152-08/overview/

The car is a 3800 LB 4 speed car with 2" headers and a 3.54 rear.

I am almost worried the intake is a high RPM piece while the cam is not large enough.

I want to have a torquey motor that will lay down a 10.99 quarter.

Any thoughts are welcome.

Edit: the intake runners were left OOTB, hopefully the torque peak will be lower than MW ports

I have 3 500 inch Motors that I use that Mopar 337 manifold on. all street cars, and all make 700 horsepower. I use solid rollers in mine also. 272/276@.050. I think they are an all-around great intake. An added bonus is that they fit under stock hoods....

Is the '337 intake even available any more? Seems like every time I turn around, MP has dropped another BB part from their already-limited lineup.

Last I heard (a few weeks back) there were three of the 337 intakes available in the system and a guy I know bought all three of them.

Don't know if MP is casting more or not. So they might all be gone if MP doesn't do another run.

They are a great intake but MP never really promoted them so most people don't know abut them.

If MP does kill this intake it would be a good one for 440Source to reproduce since it is a great intake to use with MW ported heads on a RB block. If I was 440Source I'd sell this intake with MW ported Stealth heads as a package deal. It would make a turn key solution that solves the valley tray issues and it would make good power.

Edit- He has one in stock.
