Is that on your 505"? Is your 505" a B or RB?

Mag quality pictures there Andy!

Did you see the post of mine about the pictures on the Challenger Ebay add. There were a couple iso view motor shots that were good enuff to frame. My son borrowed the iso view of the Challenger script and bumble bee stripe on the decklid and used it for his desktop wallpaper. It ROCKS! Sorry of the O/T.

PS The 470 is still raisin heck on metro Detroit streets. Might go to a roller (hyd? solid?) cam next year and EFI. Right now though the carb is DIALED in. Starts and runs GREAT after buying that LM1.

Hey Jim, nice to see you wander thru the race board.

The 505 motor is an RB block. 0.030 over on the bore with a 4.250 stroke in it. I'm strapping it on the dyno today to see just what happens with these different manifolds.

Good news on that 470. I'll most likely sell this 505 when I'm done with the dyno testing. Hopefully it finds as good of a home as that 470 did.

The LM1 is one of the greatest tuning tools ever. One of my next projects is to use the LM1 on my car and see if I can actually dial in a Holley Dominator so that it works on the street. I'm not sure if I can get it to a point where it drives super nice but I figured it would be a fun thing to mess with.

We're not finished yet but I can safely say that the Indy cross ram picked up a ton of power over the MP cross ram. At least 75 hp increase, maybe more. We need to do some more tuning and I need to stare at the dyno sheets for a bit to understand just what all we saw today.

The really interesting thing to me was that the cross ram ran just fine with out of the box jetting on the Eddy carbs. There was a little variation from cylinder to cylinder but not bad. The Indy ram wanted the carbs to be jetted up a bit. I went up 3 sizes and that wasn't enough. Probably need to go up another 3 or 4 jets sizes to get it into the ballpark. And it needs some cross jetting to be really dialed in but I don't think we'll spend the time doing that.

Here is a shot of the MP cross ram on the dyno. It makes a bunch of torque and it sure sounds brutal. This would be wicked fun in an early B body street/strip car.

To answer the earlier questions this manifold is MW port size and it only fits Indy heads on a RB block.



actually....its supposed to fit the OE type MW heads on an RB block, and seals the valley just like the OE intake when used in that manner.

where did the MP/OE X-ram run out of steam on your 505??

No way does the Indy cross ram seal off the valley. I don't see any way to use this with factory MW heads since they don't work with valley plates unless they are welded up on the bottom edge.

If someone has a picture of the Indy cross ram mounted on stock MW heads I'd love to see how they did it.

I am shocked to hear you picked up 75 HP from the Indy over the MP xram. ( Maybe even a little sadenned ). Anxiously awaiting the raw data...

Once you figure out all that is needed to get power out of stock type cast manifolds, step up and look at what is state of the art in air flow and power in manifolds.

Look at Tims' cross rams..........
$ for $ excellent return on investement.... and the bolt holes line up....

a friend also a member here, RatPatrol fabbed up pieces that were welded to the indy crossram to seal it on the block. He used edelbrock heads.

Did it get the HOWL on? Hope so

It's going to be cool to see how the modern single plane intakes match up.

I made some harebrained predictions via PM and am anxious to find out how completely wrong they were

I remember 3 or 4 years ago when Indy came out with that manifold, a friend of mine installed that intake on his Max Wedge and picked up over a half a second over the OEM cross-ram. That manifold will make power!

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.






do they make a throttle bracket or linkage to mount two 750,s holley carbs on or do you have to rig something up ?

i can see from that pic that that intake isnt going to seal the valley.....but i know of someone who had one on a motor with stock MW heads.
i guess i foolishly assumed it would seal the valley like the OE intake.


also, IIRC....i think Moparts member Whompin Wedge is using that intake on an RB block with some MW ported 906's.

Indy doesn't provide any help with linkages but I have the capability of making my own. I'll have a kit available for sale shortly although I doubt I'll sell very many. I don't think there are a lot of people who run this manifold at the moment.

If you look at the picture above you can see the fuel lines and the throttle linkage setup that I put together for the dyno. For the street the throttle would come in from the rear and there would be a bracket back there to hold the throttle cable.

The Indy 440-3 intake did pretty well. We just made one pull on it though and then ran out of time. We'll be at it again on Monday. The Dominator was super rich right out of the box so we'll have to take some jet out of it. I wouldn't be surprised if the single Dominator makes more power than the Indy ram intake when it is all over.
