Think I am going to go with the Indy 440-2 intake on my 512 ci RB that will be seeing some street time next summer
In talking with Patrick at Pro Systems he is recomending a 1000 cfm 4150 style carb that they build like a 4500 Dominator but just in the 4150 style. My question is, do the Indy 440-2 intakes only work well with a Dominator and the 4150 to 4500 adpaters that I see a lot of guys running Or do they work just as well with 4150 directly bolted on

They work well, however they will never work as well in My experience compared to a Dominator. Especially when dealing with stroker Big Block Mopars.
I have run those fancy 1050 CFM 4150 style carbs from Quick Fuel. They are nice carbs, and have better street manners.. but all out wide open throttle belongs to the dominator... I dont care what anyone says. The 440-2 Intake and adapter used in conjunction with a 8896-2 Dominator is what I ue and recommend.
Atleast a tenth better than any 4150 carb. I dont care who's name is on them... I really NEVER understood the whole Custom $1000+ carb game (by a HP Holley and save $$). Bottom line is they cant tune your carb when they live half way across the country, bottom line is the end user is responsible. And those who never touch there carb or try to tune it... Thats fine too, I always do..

Do you have MW ports? If so, the Indy 440-2 intake will work just fine with a 4150 carb. Another way to go is the Super Victor intake with a 4500 to 4150 adapter. I've used that before on the dyno and it works pretty well.

The Mopar 337 intake also works well with a 4150 carb and it is a low profile intake that fits under the hood of most cars.

I had a 950 Alc carb made by RUPERT for my car on a INDY -2 4150 intake and my car run real good but i put a INDY 440-3 intake on and RUPERT made me a true 1050 DOMINATOR Alc carb and MAN my 572 is a lot faster But if you get a good carb that`s the key. But they said INDY 4150 intake and adapter to a DOMINATOR makes more power but on my set up i don`t see how good luck.

what intake and carb is on it now?

with the Eddie heads i would use the mopar 337 intake. its perfect for that head block combo. otherwise you will need to make a leaky valley cover

i'm with Bob on the dominator making way more power than a 4150

HH,

I have one of Patricks 1000hp 4150's on my 517, it's a fantastic carb for a 700-ish horse stroker, it has a 3 circuit 4500 metering block and the response and power is phenominal....I doubt a 4500 would be worth enough on a 700-720 horse stroker to be really worth the $$$. On a light, high stall race car with no real part throttle. roll-on carb tuning concerns it might be worth some (8-12) hp on top but you'd need to have at least a more racy 730+ horse (solid roller, high CR and peak hp above 6500) to see enough of a 'real world' difference.

as with Hydraulic roller cams, the vast majority of the carb technology and R&D $$$ has been geared toward the 4150 baseplate carbs (Look at the SV1 for example), the performance gap below around 1100 cfm has really considerably narrowed over the past several years.

IMO, the biggest advantage of the dommy is the lower pressure drop at WOT usually equates to more torque on a race car, on a stroker street car the avaialble torque almost always exceeds what most can practically applied to the ground.
