So how does the stock 6.1 intake stack up against the drag pack intake? Interested in the 3G hemi deal and with that intake I could run my stock hood.

The Drag pack intake is just a single plane. It's a great intake but very peaky in comparison to the well rounded nature of the 6.1. A ported 6.1 intake will run very strong from off idle to about 6600 rpm. It will dominate a drag pack intake everywhere below 4000 rpm. You do need to have the 6.1 intake port matched to your heads, a lot of smoothing on the inside and opened to 90-92mm on the throttle body.
If you're starting from scratch on a build where you have no intake and you're going to the track a lot, I'd start with the drag pack intake.
There is a shorter drag pack intake copy without the huge pricetag that will clear most hoods. I think its by Modern Muscle.

So, for the guys that have done this swap...
I have a 70 Charger with stock front end/suspension. Is there any factory manifold or srt8 header that will clear the steering box and torsion bar? I'm looking at doing a turbo setup and what sucks about the Hemi, as I'm sure you guys know, is you can't flip the manifolds except with the Thitek heads. I assume I'm looking at a custom header deal, huh?
There is no factory exhaust manifold that will fit our chassis (A, B, E).
We've tried them all. SRT Car, SRT Jeep, Truck manifold, car manifold, JBA shorty, Eagle car manifold. They all hit the firewall.
Thankfully a simple log manifold would fit easily to go forward.

I'm totally on the fence on the next build, I have an R block to use but I don't have any real good heads. I am also going fuel injected so building a gen 3 is very tempting.

I wanted to add efi, a roller cam, aluminum Heads and a serpentine system to my RB on a fresh build.
At that point I decided to go with something that had all of those to begin with.

One of the selling points for me was the cost of GOOD heads for a BB. That money alone covered my short block. I will have about $1300 in my cylinder heads and they will flow awesome.
Mopar to the bone!!!

Has anyone determined what the max lift can be when using the stock rockers(the whole stock valve train) and is it worth looking into the aftermarket rockers thanks

I'm running a .400 lobe, which is about it for lifter travel with the stock lifter guide that keeps lifters oriented. There are no aftermarket replacement lifters available, But, supposedly, link bar lifters are coming. Not sure when though.

I believe Steff and 340rick are running larger cams. I believe Steff was trying to increase the height of his rocker stands when he split one and then Member Jerry came to the rescue and made billet stands that look awesome.
Those guys would probably do a better job of answering your question
I bought my intake from Mike Ware for $550 but now I see it being sold for almost 800 from modern muscle. I would call Mike before buying it from those other guys. The word is the tall plenum is really needed
I designed the Rocker Shaft stands out of necessity, but it worked out for the best. I wanted to raise my rocker shafts to better the geometry and made the mistake of over tightening the rocker shaft bolts with shims under the shafts. It cracked the stock rocker mounting bosses. So, the stands were designed to salvage my heads and still put the rockers where I wanted them. Jerry helped me out big time and made them for me, and to show my gratitude, I gave him the design for his product line.

If you're starting from scratch, buy a set of 6.4 apache heads. They come with a Ferea 5000 series valve factory and can accept a BBC valve spring like a PAC 1520. $1220 with "core" charge and add in shipping. Matt Deane in the parts department at Glendora Dodge has a set in stock. I know because I'm considering a set right now...350cfm OOTB with room to grow! http://modernmoparforum.com/topic/12135-57-61-and-64-hemi-cylinder-head-comparison/

It's so easy to crack them. I've never done it (yet) but I've seen a friend right next to me strip one hole and crack the pedestal on another.
I torqued mine last week without issue...thankfully.

1220 is a single head right?
If not I'm interested in another set. Matt
