499" RB, ported Eddies, hyd cam about 240*, mostly street, 69 Charger, 3.55 gears, 727.

I am pulling the big solid cam and big open intake off this engine and want to mild it up a bit and install it in a more driver friendly combo. I would prefer to run a Dominator, but am open to a big 4150.

A 337 would be nice, but............

What intake would you recommend for a mostly street driven car. And it would be nice if it would fit under the hood with a drop base air cleaner and maybe even lowering the K.

Thanks

Does "ported Eddies" mean MW-sized Performer RPMs? Or are they still standard port (in which case a '337 wouldn't work)?

My ported Edelbrock's made 650 with a BG flowed dom. and a gasket matched, Weiand 4500 Team G. 493, .660 Comp roller, 12.9-1. 112 leaded race gas. Went 145mph in my 2,700 pound Challenger right out of the box.

OP, if your using CNC ported Eddy RPM with the stock size 440 intake gaskets I would and do use the Eddy Performer RPM intake on a lot of builds like yours with those heads along with a 950 or 1000 HP Holley 4150 carbs
As far as the drop base air cleaner clearing your hood I'm thinking they will

If his heads have been opened up to MW size, somebody (NOT ME!) has just listed an Indy 440-2D intake that looks to have been CNC'd on the port exits to MW, too.

Can you still buy a 337 ?

Dave H, what was your stripe rpm to knock out 145 mph at the stripe? What is are Your rearend ratio. Tire size? While I'm at it, are You running a glide or 3 speed? Sorry for hi-jacking the thread but I want more mph and I think I need a lot more rpm than I'm spinning now

I think it's to the point where it's only if somebody who has one already is willing to sell it.

Modern CNCed them a few years ago. They are bigger than stock, but not really MW.

My Modern Eddy's flow 325 cfm on the intake according to the flow sheet that Modern sent with the heads back in 2012. Dave , I sent you a PM.

FWIW those heads and cam are now in/on a STOCK 400. It runs great with an OOTB Performer RPM and an HP 750 with a 50cc acc. pump. Sorry I missed the whole "tame it down a bit"...

I am a bit surprised at the dual plane recommendations for a 499" engine. I would have thought that a DP would be a "cork" in the intake of an engine that big.

But it's not???????

I've ran it up to 7,000 rpm. It runs great! Idles like a champ. If I drive it everyday it starts right up and away we go. If I let it sit a few days it's a cold blooded buck snort!

Anyone know off hand which is shorter; the Indy 2d or the Eddy RPM? I'm thinking that height will be an issue getting it all under the hood.

For me, the gears and converter would guide my choices.

Okay, tight converter. Well, as tight as your going to get with a 499" big block and 3.55 or 3.23 gears.

I have had PTC and Ultimate Converters build me as tight a street converter as they can for my 540 Hemi. Ultimate's converter will flash to 4,200 and the best PTC could do was north of 4,500. And that is with 3.91s. Not exactly what I call tight, but was all they said they could do with the cores available.

The Ultimate does feel tighter and the car feels more responsive down low. Just better for driving around town and cruising.

You're the one who said you wanted to tame it down. If you don't want to lose the power, maybe you should leave it as it is. It's tough to have it both ways.

Performer RPM is a good choice for a big street engine. I've run various Performer RPM intakes over the years on a lot of 500 inch big block Mopar engines. Hard to beat that intake on the street. Once you get the engine past 5000 rpm a single plane will work better.

Lots of love for the RPM. Looks like the way to go.

If you want less stall, you just need to use a bigger converter.

I’d be pretty surprised if a factory 12” converter stalled over 4K behind that motor.
