It looks like a nice build. Cam choice is like socks and underwear. Your choice on what you want or like. That F.I. set up likes a wide centerline. IE 112 or better IIRC.
I particularly like the Crane roller cams for something like this. I think a roller is worth the expense at what your doing. Broader torque curve, hi lifting cam.
I think the heads are expensive myself. But a moved pushrod is the way to go for biggest power gains. I myself would rather look at a Mopar head than the Edelbrock heads at this level in part because of the cam I'd choose. You would need to remove any stock valve gear from the Edel. head in favor of the matched and better valve controling Crane stuff.
So cost, I think, would be in the Mopar heads favor rather than re-working the Edel. head.
I like the Edel. F.I. except when a change of cams comes in, you need to send the cam card and computer chip out to Edelbrock for programing so it works right.
I had already e-mailed Edelbrock about this setup before I posted this thread, and heard back from them prior also. This is what they said:
The Pro-Flow #3526 system will support between 450
to 480HP as delivered and with a change to 35lb/hr
injectors could support between 560 to 590HP. The
change to the 35lb/hr injectors would be $40.00 and
is done after you receive the system. When you buy
the system you take the 29lb/hr injectors out and
return them with a check for $40.00 or a Visa or MC.
Here is the only bad news for you the Comp Cam you
are interested have a very narrow lobe separation
angle so they do not work very well with any FI.You
might want to look at our RPM cam that has plenty
of lumpy lump and will make good power in your 408
part #7177 234 Int and 244 Exh on a 112 LS.
I think, being Edelbrock, they will be buyest to there products, so I'd imgaine that they would recommend there RPM heads.... So I want even go to them and ask about best heads.... I, personaly, would rather have a non-buyest opinion and hear from people that run, and have run different setups. They have good stuff and all, but in some areas, there are better things out there...
As for Mopar heads, gonna need some input, the only set that I've looked at threw Mopar is there BB Stage 6 (new casting) heads.... That's about it. I'll start this one off at this link:

And go from there. Like I said, if I can save some money, any where and every where throughout this Duster project, I'll go for it, lol. After all, two projects.... But I will probably make my '72 Charger the long term project being more rare than the Duster, heck, the Charger has the fender tags, lol. Anyway, like I did, originaly, with the Charger, I'm not setting any numbers for the motor, but I do want it to really move. The Charger will be the cruising car (383 crate motor I'm looking into for it will be 500/530 so it will move too), and the Duster will be the upsetter. I am wanting to swap the rear axle to an 8 3/4 with a 3.91 SG, maybe 4.10, and if I can, run a built A-518 behind it for the O.D. The should help a bit. I do plan on running TTI's, but if I can find a comparable set, for less, once again, see above... I figure the SB stroker motor would be better for ramp speed on the street than a BB, as far as costs, kind of a toss up I guess between the SB and BB.... Each has there advantages and disadvantages. I feel the SB would be a better choice for several reasons. The 360 b/c there are so many versus any other motor, at least around here that is. Price, heck $125 for a complete 360 (needing rebuilt of course.....) come on now. And they said they have several of them... Anyway. I'll have my SB car, and my BB car. The SB will, or should, be easier to work on, clearance wise than the BB. Ect. Anyway, I'll continue later on, just trying to give a better idea. Also, I'm gonna try and keep the weight down as much as possible with this car, so.... I plan on going to a fibergalss hood with six pack scoop for better air cleaner clearance, and looks. Anyway, bring on the questions, comment, concerns.
