i had the snout on mine machined down 5/8. Others have had the neck cut and rewelded

Which holes of the 5.7 crank mains should be plugged, there are 4? Read this back a ways but can't find the post

Thanks for heads up .. I did t want to weld it ...:(
Any pics you can share of your finished mod ?

I know this is about the engines but has anyone tried using the 5 speed automatic in a non computer controlled car. Just looking at it reminds me of a big can of snakes, but it sure would be cool to use.

The NAG-1 (LX/LC cars) and 545RFE (Trucks) are all computer controlled. I don't know of any stand alone controllers for these transmissions. If you want overdrive, go 727 with a gear vendor or an early 518 without a computer controlled governor. There is little to no support in the aftermarket for these transmissions outside of a stock computer/harness retrofit application that includes the engine control for fuel injection.

Pre 09 5.7 blocks can go 4 inches in bore but its best to have it sonic checked to be for sure. Will require a custom piston at this time till others start really doing it. Andy at pwr has one running for a few years now on his own vehicle i was told by him. Cylinders are still thicker than the 6.1 as well.

Again sonic testing the walls is best when taking that much material out.

Im doing a 4" 5.7 05 block with eagle heads an 80mm billet turbo.

what is the max lift for stock rocker arms

Guys say .650 is it,,,,

Yes, .650" is pushing it. I'm living it right now.....

If you can I'd like to see this thread broke down into
different parts so its a bit easier to get the info... as
in
Blocks.. which ones are best for what reason
Cranks... what will interchange and the stroke of each
and if there is any diameter changes
Cams... max lift, duration and so on
you get the idea... I've been searching on here for different
info but its sorta hard to find and I dont want to ask if its
already out there

I agree with you. Larry is close to having my 5.7 ready and put it in my Cuda, and I'm still having some questions and having this broken down would make it easier to find some answers without using the search tool...

With as popular as this engine is becoming with all of the new car sales, and the swaps that are going on. Maybe we should have a 3rd Gen Hemi Section in the main forum, and break that up into the different sections. That way we could have a section for the street guys too.

check out G3 HEMI SWAP on facebook.

I would like to see a Gen3 section also

I have a ton of swap info I could contribute.

Yes please on the Gen III section. Organization would be awesome! I would contribute what I have discovered as well.

I would add anything I could too. I already found out that I ordered the wrong ignition harness for my FAST fuel injection system. I ordered the 5.7, but because of the way the motor is set up, I needed the 6.1 harness.

And I 'd like to add, the reason I only had one mistake so far is the fact that I have such an experienced person like Larry Griffith doing the work. I was just going to go with another small block until talking with Larry.

Having started this thread, I heartily agree it is time to gather all the info and add it to some other much more easy to research form or section. I think the original thread should stay for the purpose of info gathering, but a tech article or section editable by MODs only would be a great way to do it.

Definitely time for a GenIII section. Information is extremely scattered and plenty of it is being kept as tribal knowledge. This whole thread could -easily- be broken down into sub-threads of "power steering", "fuel system", "ECU/Control Units", "Oiling and Exhaust", "intakes", "heads", etc for in-dept discussion of each area.

If nothing else, I wonder if there is some sort of free Wiki-Page we can setup for members to create their own tech articles and people can add to it, reference other pages, etc. Those are exceptional online databases that are easy to create and search.

I agree this IS the future for us.

Two questions, any problems putting the 6.1-6.4 crank in a 5.7 block,maybe cam line up? Next, how or what is used to mate the 904-727 trans to the 5.7? 5.7 is an 2007.
