This thing looks promising. I need to get it on the dyno to see how well it works but so far I rather like it.

It did take me a couple of hours of grinding to get it to clear the MSD distributor and to get the port matching correct. I still need to put it in the Bridgeport and counterbore for the intake bolts since they are cast at an angle.

I'm thinking it should run pretty good with a couple of Eddy 800 carbs on top but I'm wondering if it might just be a cool street setup with a six pack? I know the stock six pack setup runs out of power on big motors but this sucker might just work.

Here it is with the 4150 inline top in place. I'm thinking I'll call up Ken and see if he'll send me a 6 pack top. Might have to wait until next month though since the VISA card is still smoking a little bit from the last round of parts buying.

With the huge plenum volume, it mey not be a very good street intake even with the six pack.

I have a friend that ran it for years with two 800 eddies, and he switched to two holley 950's and likes them a lot better. He also went with 3.73's instead of 4.10s since the car is streeted and it runs nearly identicle et of 9.70's with the same intake. I would go with a set of holley style carbs over eddies....

Looks Sweet, Does It have the max_wedge ports? What Block is that?

That is a cool shot of the ports with the top off!

Andy where did you get them valve covers and where can I $ a set of them?

my vote goes to a 6 pack lid with 3 4412 holleys and spacing for the center hung float bowls

or how about 4 2bbls, one over each set of runners in a 1 to 1 ratio. bad gas milage though

Yeah the head of the bolt hits the manifold at an angle so it would dig in and not seal up. I didn't want to run it that way since there is fuel in the manifold and I don't want it leaking down the bolt hole into the crankcase.

To answer the earlier questions this manifold is MW port size and it only fits Indy heads on a RB block. I guess it might fit something like the new Victor heads but it is designed for the Indy heads with a valley cover.

The runner length is about 9 inches long so it is a little longer than a tunnel ram but not nearly as long as the Max Wedge cross ram. So the torque peak should be a little higher. Ken says it carries the power higher up the rpm range and that it makes more power than a cross ram and keeps making more the higher the speed goes. He figured it should be good for 50 hp on my 505.

It would be nice to see more B block intake options with a M/W port!

So what makes these STR-like crossrams better than the original Edelbrock versions, and what sort of 'ka-boom' safety / pop-off / backfire valve is on that thing from the factory?

They are available for one thing and they have MW port sizes.

Hey Andy ... can you post a pic of the front were you had to clearance it for the distributor?

I had to grind away a bunch of the mounting bolt boss since it was running into the distributor. The odd thing is that the boss isn't even needed that low since the screw is only about 1/2 inch long. So it was just a hunk of aluminum hanging out there.

Then I had to grind a shallow cup into the front of the manifold to clear the side of the distributor. It was probably 0.060 thick section about the size of a silver dollar.

Andy, as far as which set up will make the most power I'm betting on the stocker type cross ram with the 1600 CFM. Make sure and watch your jetting via the spark plugs, AFR sensors and EGTs if you can. BTW I will be glad to do some track testing on those combo in my car with my MW port SR 527 motor, Let me know if your interested in doing some at the track testing.
Oops, sorry. I put this on the wrong post. Anyway the offer still stands.

That intake sure would look nice polished out like that vally tray!

A few minutes on the Bridgeport fixed the mounting surface issue for the hold down bolts.

Cant wait to see the results on this one

You'd think they could cast the holes correctly Nice job on the fix
