What does everyone like for a MW port intake? Indy? MP 337? Edelbrock SV?? Thanks! Ted

I like my Indy on my 440-1 heads...made 60hp more than the Indy x-ram. About 1 1/2in of clearance to the scoop. 337 is a good piece also. Have Radar clean either up and port match 'em! Happy Holidays Ted.

Thanks,Billy!! Yes...Radar will get the work...It will be interesting to see what the heads do after he starts grinding on them...I hope you have a great Holiday and we will see you guys at the track next year...Tell Dan I said hello!!

Dwayne put the Indy 440-3 on mine when it was up there last.

Thanks,Dap! I have spent about 2 grand on parts for this thing since late fall...Another 2 grand and it should be ready to go!!

The Indy single plane intake is a good race piece. It may not run the cleanest on a "small" (440 CID) motor with a large cam (276 degrees at 0.050"), at 2000 rpm, but it works great with a high stall converter, etc.

Buy the Indy 440-3 intake and if you can fit a 2 inch phenolic or wood clover leaf spacer on it try that Using a 440-2 with a tapered spacer just adds phenum volume, adding the two inch cloverleaf spacer on the 440-23 does the same thning. Monte Smith has debunct the 440-2 w/ the tapered adapter myth

Thanks,Cab! What are you guys using for a valley plate? The Indy ones I see usually leak...

I have only used the Indy valley covers. Dwayne used the right stuff to seal them up and never had an issue with leaks.

What do you have left to do?

If that works for Dwayne...That is good enough for me! As far as what is left...Get ladder bars installed..Front brakes put on,get the heads done..buy new intake,needs new slicks..I may go waay over budget here!!

Thanks!! So...The 440-3 is the intake to get??

I think there are only 3 choices for RB, MW and 4500. Those choices are the Indy 440-3, 440-3X and Edelbrock Super Victor. (B1 intake can be used with adapters but frankly that is an expensive and painful way to go these days)

The 3X is very large, the 440-3 and the SV are similiar. I've used all of them and I'm not sure I can tell the difference on the dyno. They might work differently at the track. I'd probably buy the Edelbrock if it was my motor but I'd run the Indy intake if I had one on hand.

I plan to run the Indy dual plane intake on the eng I am building. It will have EZ heads and be 493 cubes. They say its a great intake for a street/strip car like mine. Ron

The Indy DP is a good manifold but it isn't MW or 4500. It can be opened up to the MW port size and an adapter can be used for the 4500 carb but that is extra work and money.

My Indy dual plane will be opened up to Max Wedge size but I dont plan to run the 4500 carb at first. Ron

Andy Why do you prefer the Victor? They are similar in price correct?
In fact BM had 440-3 for $305 a couple weeks ago.
Thanks, Don

I'm a huge fan of the Indy 2d, especially in MW form and additional radius work in the lower plenum....a 360 CFM dual plane is a pretty serious piece that will keep pace with most of the heads out there. There's at least 30HP in the radius work out of the lower plenum, the upper plenum is pretty much good to go once you open up to MW.

I too wish it was available with a 4500, I've thought to take mine to see if it can be Bridgeported (and I was secretly hoping Andy might have already sized this up ); but my pro-systems 4150 1000hp seems to be doing fine....6800rpm at 517 cubes. To be honest it runs so good I haven't thought to open the hood on the car in a couple months

My combo (380cfm heads) leaves some top end power on the table that I might need a single plane and a .700 lift cam to reach my in my old age I guess I'm very happy to leave well-enough alone...I can't bring myself to do anything that would alter the Formula 1-like throttle response and roll-on torque of this badazz dual plane.

hi my name is Rich i am new here. i read in the post above from streetwise about a indy 2nd. is there a 1st and 2nd gen indy 440-3 . if so what is the difference?

Welcome,Rich!! I am sure that someone can answer your question..So I will give this a

Thanks for the welcome. i just pulled mine this is what it looks like in side.

The early ones didn't have the port dividers come up under the carb. like yours and the base was not clover leaf like yours, is what I remember I saw one early one (440-3) before I bought my 440-3 which is like yours, have you seen a 440-2? If so they (early 440-3) look like the -2 but with the 4500 base and bolt pattern

Thanks i was told that mine was one of the early ones . i saw a pic of another one that looked better inside. to my understanding this is a stock out the box 440-3 also. i know mine is i bought it from indy new

Rich,
You really need to start a new topic for your question, but a quick 2-cents:

That looks like the latest casting.
The top of the runner dividers under the cloverleaf are cast and not machined like the previous version.
There may have been a much earlier version also. Those intakes didn't have the 4 large, oval injection bosses, but rather 8 small round bosses slightly higher on the runners.

We need some Indy Intake pics and carb height dimensions to add to the Moparts.com Tech archive.

My attachement is an old 400-3, and the injector bosses have been fitted with injectors, but you can see the old style Indy lettering, and the smaller, round, bosses.

ok thanks Rich
