With a valve job and port work on some Eddy magnum heads I saw 282 cfm. It was enough air for 498 hp out of a 360 with about 10.5:1 compression and a hydraulic roller. My own personal motor has the earlier LA heads and they have more meat in the ports for a little more aggressive port, but they don't flow as "easy", in my experience, as the magnum versions. I've currently got mine flowing 312 cfm @ .700" with a 2.080" intake valve. I've plugged the pushrod holes and plan on using offset rockers. Problem is, at the amount of effort I'm putting into the eddies, I could have done some Indys. But, I already had the E's. Just can't get enough cross section out of them to flow the big numbers. We've got a hydraulic roller'd 408 with some oval indy's I ported on the dyno right now. I hope to get it running tomorrow, but it'll probably turn into next week with the other work that needs to be done. Guess I'll throw my hat into the ring. I've got more experience porting the E's than I sometimes like, but I seem to have a God given talent for getting them to flow air. Number's in the signature if you're interested. Jason. They say a picture's worth a thousand words. Well here's a few thousand words.  little wave in my port's wall, not finished yet.

Mark,  As good as your car runs and your power is with the J's, my gut is the eddies (even with a full tilt port job) may not be large enough of an ET drop to make you happy. I think you'll need to see 320 cfm to really make you smile, I would strongly consider either a W5 or a brodix to get more CFM and Intake port CC (which is what the big motor needs). You can only get so much fuel through a port.

It seems I've got a little more weight than most of you for a Duster. Kind of tough to cut it down since I'm pushing 330 without the race car!!!! I could lay off the enchiladas and learn to like broccoli and probably pickup a few hundredths!
The thing I'm struggling with is that obviously the Indy kit brings forth the most power at about $4000...the Eddies(from Indy) are still $3700(quoted by Indy) for quite a bit less power upgrade. Although I don't need as much power gain as the Indy 360 will provide it doesn't seem to make economic sense to buy the Eddies unless I can find a similar package at a heck of a lot less than Indy quoted.
I don't want to run 9.99 in this car. I DO want to pickup a few mph and a couple tenths which probably translates to 50-60hp.

Do you know the Sloan brothers, I think they maybe selling the top end off their current motor, Brian at IMM did the heads so you can't go wrong there.

Mark, dont do the CNC stuff. Buy the Edelbrocks and have Brian @ IMM port them and pick out a cam to compliment the new heads. Your intake, rockers and headers will bolt right up making it the most economical choice. Indy heads will be WAY more money just because you wouldnt be able to utilize anything on your current top end. I would sell you the Eddies off of Dougs engine, but Im using them on my wifes hotrod once I finish up DOugs new 411 Indy headed engine with some IMM port work. Mark, what did you end up doing with your superstock 340 engine?

Just don't plan on picking up any HP if you use Indy's kit with OOTB -1 heads...
those heads don't make any more HP than eddy heads OOTB. They flow 260 cfm MAX on my bench!!
They NEED porting to work like they should.
Change the cam, ported eddy heads and your super victor intake and your going to go 10.teens I guarantee it!
is the super victor that much better than the victor 340 with eddys in a combo like he running? Just asking, thats all. Just want to see if I am leaving any power on the table.

What are others seeing if any in the SUPER VICTOR INTAKE ?
I'm running the victor 340 with super sucker .
wanting to buy it if the gain justify's the cost .
Also in what stage's of port work .
they are pricey from hughe's .
Going on my 418 .

When the Edelbrocks were stock and unported, we used a Mopar M1 manifold. We then had the heads ported by Brian @ IMM and at the same time I switched to the Super Victor. THe car went from 11.20s to 10.60s. I wish I would have done the manifold swap after running the ported heads. So basically I cant even give an honest conclusion as the affects of the manifold vs. another one. We have a 2" tapered spacer ontop as well and the manifold is TALL.
