Why did the price of a set of 4 non mds lifters with yoke jump in price to $167? Even the non mds yoke alone is listed at $167 without the lifters!
What gives?
Not sure if that was directed at me or not, but either way I have no idea

No not at all. Just wondering if anybody knew what's up with the $100 price jump.

Greg...Modify your 5.7 heads. Glen Knowlton, Joe Mondello, both men, May they RIP, agreed my hand ported G3 Hemi heads were kick azz when I welded the 5.7 up the quensh pads and installed bigger valves. Port velocity/air speed was in the 345 range at mid lift number's. Exh:int ratio's in the mid 70's. You won't see those numbers at mid to high lift with 6.1, Eagle or Apache heads.

Now running an Eddie Thunder 800cfm on a 6.1 SRT G3..through an Indy Modman intake. Thru my 12 sec 318/392 stroker with ported 360 iron heads - this carb was running 107 main and 104 secondary jets. on the HEMI...370 cui with a smaller cam and Lower comp....its dialled on at 96 primaries and 74 secondaries!!!! ...and making 50hp more Superior combustion dynamics anyone?  
67 RO23 clone with 6.1 SRT Hemi and dual quads. Soon to have Drag Pak induction and Throttle body.

I am interested to find out why some guys are making excellent power with reworked early 5.7 heads, and the factory is able to do better with the Eagles, 6.1 and Apaches that have less port velocity. Hemidup did a set of early pre 2009 5.7 heads that worked extremely well for him, and out performed supposedly better heads. There is something to be learned here beyond just port velocity and flow numbers.

Same engine build just different heads. Ported 5.7 vs ported 6.1. The 5.7 heads had 2.05/1.57 valves vs the the ported 6.1 with 2.08/1.60 valves.

We will be assembling our Gen3 Hemi next month and have it on the dyno by the end of the month. Unlike previous engine builds for CC where we take pics BEFORE the build, I will have BEFORE pics available, but we will be tearing the engine apart AFTER the dyno session and taking pics then.
We are looking for problems as well since we have to stand behind every engine we build and we don't want anything coming back or failing!
Once we do that, I'll probably start a thread about things we find. I believe it won't detour any work away from our shop but more importantly bring us work by helping others out and sharing info that will encourage potential customers to have us do work for them because we instill confidence BY SHARING our findings.
We don't have to give away all build info to help guys out so they have reliable engines IMO.
From what I can see, some light massaging of the passages will make a big difference, Manley oil pump and timing set, aftermarket crank is a nice upgrade (plus more TQ and HP)if you go with more stroke.
Our builds will be based on 5.7 blocks and 09' and later 5.7 heads. The cam cores are really cool looking as they are very beefy and heavy!!
Just received our Ritter intake so now it's time to finish machining and assemble. We're also using Clevite H series bearings and Diamond pistons.
Crank is a Scat 3.900 unit with a 6.200 rod so we can use shelf Diamond pistons meant for the 4.050 stroke and 6.125 rod.

 Or did I miss this in another post..? Still trying to get more info

Since I don't have a time schedule on this build, I keep putting it off because of how busy we are right now. I have everything ready except the rocker tie bars.
It will be finished before the end of the year as I don't want to drag it out any further than that. I also have a ProCharger build using a similar combo to this is store for next year...that will hopefully see the magazine too.

Any body have new info or input on this? I am interested in carb performance mainly, but any info that deals with either carb or injection would help us in learning why there is the difference between factory and aftermarket performance levels.

Greg, if you want to go carb your best bet is HHP for an intake. Any of the low rise offerings seem to really kill power from what guys have been reporting. Rat Patrol on here went to a dual carb Modman and says it was an improvement over a single carb though even on a mild 6.1.
Mopar to the bone!!!

Bump to keep this going. Could you all add links to your gen 3 threads? Then maybe the title can be edited and it can be made a sticky?

Just a fwiw on "issues" - Piston to Valve is very close on the stock 6.1 also.
We ended up with .068th using a 110 lsa and a 218/227 duration.
The LSA probably hurt the deal....But for the life of me I have no idea how guys are running 230+ duration cams with stock slugs.......
Modman Intake - appalling bottom end signal, HUGE pump shot need to overcome a lean bog..even with two carbs.....and a full height divider......
Valve springs - PSI 1511 requires custom shims, valve seals and retainers - Craig from Thitek has a great kit.

My advice to anyone that wants to learn would be to partake in a web chat with the SRT engineers. They hold them periodically on LX Forums and you can ask anything. Those guys HAVE the answers to your in-depth questions. http://www.lxforums.com/board/forumdisplay.php/350-SRT-Engineers-RoundtableWill SRT392 intake, pushrods, valves and springs fit the 5.7 HEMI?
Will Challenger SRT392 suspension fit a Charger LD?Quote:
Some 6.4L engine components will swap with a comparable 5.7L. Valve covers, rocker shaft assemblies and pushrods will swap. Valves and springs are specific to each application as well as the valve seats and machining. The intake flange and bolt holes will allow a 6.4L intake on a 5.7L but your port openings are different. The 6.4L SRV valve in the intake will need a proper calibration as well.
Get your info from the guys that built it
