Thats some good advice right there 
I have had alot more trouble tunning my EFI than I anticipated. If I had it to do over might just save the $$$$$ and throw a carb on it.

Just a shame the majority of carb intakes don't perform as well as the EFI intake at "streetable" RPM. Ill be very interested to see how my Modman behaves in a couple of weeks...

I'll bet you had the same issues with the first carb that you ever played with.
You'll get it where you need it in time. Then your engine will last longer due to better ring wear and start instantly.

Head gaskets info for 5.7 6.1 6.4
Who has part#, thickness and bore size for factory head gaskets.
Plus what gaskets to use on what block? Do they all interchange?

You must match the gasket to the block your using, meaning if you use a 5.7 block you must use 5.7 head gaskets even if you bolt on a set of 6.1 heads. btw the 5.7 has a right and left hand head gasket and are not interchangable from side to side. The 6.1 block is watered differnt than the 5.7 so if you use 5.7 heads on a 6.1 block you still use 6.1 head gaskets which are interchangable from side to side and depending on piston choice using the 6.1 block with 5.7 heads you may have to widen the chamber and the factory gaskets are .040" thick.

How much abuse can the stock main caps take? At what point should one switch to aftermarket caps?
Is there any difference between the G3 & G4 caps?

Half of the reason for going to MS3X with my Boosted Magnum 360 was so when I went to the G3 I would already be up to speed. The new auto-tuning feature takes much of the problems with EFI Tuning inexperience away from the equation. You just drive it, and click the "yes" button when it says it wants to change something. Even a caveman like me can do it.
I am watching this thread very closely - since it's where I am going in the near future. I need all the info I can gather.

Thats a good question. One of our G3 dyno mule's was pushing a 1000 boosted hp and the other one, N/A was spun to 8,000 rpm. Both engines were torn down after every session and I've never seen any indication why you would need aftermaket caps. BTW, both those motor's used ARP stud's.
Have a G4 sitting here, just haven't torn it down yet, but I'll go out on a limb here and say that there might be a difference. Board member STEFF would know more about the caps since he's had the chance to build both the G3 and G4.

I'm going to take a guess and say yes the did change the caps.
But knowing my luck I will probably be wrong

No difference in the Caps that I can see, between G3 & G4. They are still powdered metal. Everything crank related fits the same, bearings, thrust halves and the rear seal retainer. Even the ARP Studs work the same.

YES I was wrong
Good info that will help with future builds. Everybody always remembers the big stuff. But IMO it's the little stuff that kills you. Thanks STEFF

This may be a brain fart on my behalf, but doesn't the G4 use cross bolts on the #5 main?

My 09 5.7 has 5 cross bolts on each side.

Some things I have noticed. When I used the high performance series bearings and the stock mains on my 6.1 crank, i had .0018" main clearance, a little tight for racing. Callies makes a bearing that adds .001 oil clearance, its coated, and 3/4 groove. The next thing as of 3/12/13 the set of 4 roller lifters thru mopar that were 60$ cost and 80$ list are now about $140 cost $230 List. So if you know a parts person you were looking at 240 or so for a set is now 560!!! 53021720AC was the old part number and the new part number is. 53021720AE justin

I paid $160 from a dealer online for all of my 6.1 lifters some time last year. My friend actually found the deal and bought a set too.

Just FYI Mopar Parts wholesale on-line still have the old price listed for a new number. I called them before I placed the order. They said they would have canceled my order with that price increase.
So just a heads up for those of you looking at those sights.
Good find on Jegs!

Just an FYI, picked up latest issue of Mopar Now and they picked up a used 5.7 too see how far the bottom end can go before it poofs. It was a used core engine with 55k on it that they opened original ring gaps, put in cam, fresh heads etc. It made 1100hp with original pistons,rods,bearings,crank and rings before it ran out of turbo with a safe tune.
