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
