Well, been piecing this together a little at a time, so far this is roughly how far I've gotten... What yall think? going to look good under the hood of the '72.... Lurking beneath those nice and purty new valve covers is an purty set of aluminum roller rockers in a 1.6 ratio held down with a stud kit. Before I can bolt this to the 440, I'm waiting on the head gaskets and head bolts to come in... Gaskets are going to be Cometic (ouch), and 12 point ARP head bolts... For those who don't know or can't tell, the heads are 440 Source Stealth heads that were reworked by Jeff @ Modern Cylinder Heads, the valve springs that are on there now are matched to the cam that I'm going to be running (it's in the closet)... The intake is an Indy dual plane that's been taken to max wedge ports (math to the heads), valve covers I got off ebay, ect.... Once I ge the motor up and going I'm going to be using a Holley Double Pumper rated at 850 cfm, along with a K&N X-Stream air filter. There will be a 1" 4 hole phenolic carburetor spacer providing enough linkage clearance, being that it's being raised, the filter base is a drop base style.... Can't wait, (Laughing Out Loud).

NICE!!!!! That intake looks decent could almost pass for a stock intake if you painted it lol.
I'm ordering the stealth heads CNC ported from them for my 400ci, i can't wait and when you get these put on and set up take some pictures and get a video clip of this beast going!

Video clip will be a challenge since I don't have a cam corder or anything like it, nor do I know anyone who has something that can record video that works . My heads were taken almost to the max, as far as the porting goes, it might as well be at the max... To the best of my knowledge, the Indy intake that I have is the biggest dual plane intake out for bbm right now.... I will get pic's one way or another once the heads and intake are on the motor, plus car, carb spacer, ect ect ect

Well, the brand new Cometic head gaskets just got dropped off... Still waiting on the cylinder head bolts to come in... Couple other things I need to get too before I switch everything over....

Heads don't look too bad... I'm surprised they used the Indy rockers with such a cam, they should have just used the T&D set up, more costly, but they are stronger... If you get these heads, I'd imagine that you'll have to change the springs, and replace the rocker arms that are messed up.. Not sure what the price per rocker is for those heads, but last I heard you can still buy the rockers individually instead of as a whole kit.... Keep in mind the size of the combustion chambers, when selecting a piston, don't think of the 80 anything chambers, they have those set at 75 (I think it said) cc chambers so... The way I got mine setup, great for street, and can handle much more...

I did look at a complete Indy rocker setup on a website somewhere...$1,100 OUCHY! I am just impressed with the flow numbers on these Indy EZ heads...especially when CNC max-wedge ported. Still have not desided to build the blower engine first or a high compression big cam engine combo. Cant afford to do both. I could build a mild iron head non-stroked for now then build the blown alum head engine to swap in later... I have til Jan to deside but really really want a blown stroker.
How much power can 23 spline A833 handle?
Sorry, starting to hijack your thread too.

Gary, I aint worried about the thread, figured I'd throw this up online as somewhat of a what have you been up to kinda thing. As for the heads, unless I misread something, I don't think those are the Indy 440 EZ, I want to say that those are the 440-1, there is a bit of a difference between the two.. Might want to look again, also check out Indy's site, you can compare the EX and the -1 stuff easily there. The EZ setup is closer to factory, it can use factory rocker arm type stuff, where as the -1 I think can not, more off set that the factory. If I had the money to go the Indy route, I'd love to have an Indy top end, but I did what I could, and I don't think I did too bad so far, . As for the A-833, I have no idea..... If it were the 727, then maybe, but no matter what I'd suggest rebuild/modify it just to be on the safe side. But as I said, the A-833 couldn't tell ya. Hopefully someone here can chime in on that one. This much I will say as far as high comp motor vs forced induction motor, neither of the two are alike when it gets down to the bottom line, . Generally, the forced induction will probably cost more, and if you're running vacuum stuff, you're probably gonna have a problem and will have to run either a vac pump or reservoir.. Saying that, if you have a good sized cam, you'll probably have the same problem. The motor I'm building pretty much, has a decent cam, but with the way it's done, I should still have a decent amount of vacuum, how much, dunno, I should be able to figure that out later on once the motor is running... Usually when running a forced induction, depending on the amount of boost, depends on just what all you will need to do. Either way, I'd suggest a main girdle, aluminum main caps, and of course, main studs. I'd like to run the aluminum main caps and main studs now, but that might come along down the road.... Check this page out: www.tdmach.com/page12-13.shtml pay attn to page #13, bottom left hand side, the guy who I got the intake and these rocker arms from had to upgrade to these because of the cam that he is running. The folks who are selling those heads that you have listed above, should have been running something more like these due to the kind of cam that they were running, these rockers are made to with stand those kinds of pressures... On the build that I wanted to run, being that I too was looking to run a solid roller cam, I was gonna end up with one of these rockers: jesel.com/index.php?categoryid=8 yes, high dollar.... That build want be going on obviously, lol.
