Got the cam bearing problem corrected. Ordered another set from Clevite,,different design this time from first order. They worked OK.

Who makes an oil ring pack to these demensions... 3mm X .100 X 3.927. I need some to fit the pistons I have, that may have been speced wrong or the manufacturer made wrong, or who knows,,,NO one is owning up to the problem. Total Seal has a .110 that I can probably grind to fit,,but, that is the closest I can find today.  Any help would be appreciated...

Just made an interesting discovery for the low budget 5.7/904 guys...
with the stock 5.7 flex plate you can use a jeep converter in your 904 or it looks like you could just knock the ring gear off you regular old 904 converter and use the 5.7 flex plate.
The flex plate I have is for an 04 durango 5.7 and has the same converter bolt bolt pattern and ring gear diameter and looks like it holds it within a fraction of an inch of the same position off the trans mating surface of the block.

Good news but i would check the trans to engine centreline.Had a external BM flex plate on my 360, and it cracked. Couldn't figure out why until I checked it. IMO if it is off, it stresses the flex plate

How much horsepower would a factory 6.1 intake support N/A? I plan to add a procharger down the road a bit and wonder if this intake would be a good choice to use for both applications. My target hp was about 600 N/A and about 900 with some boost. 
It depends if you're talking wheel or crank HP. For 600 crank HP N/A, a ported 6.1 Hemi intake will work fine. The long runner design of these manifolds are not extremely efficient for a forced induction application. However, I have several customers running the 6.1 manifold with forced induction and making close to 800 crank horsepower with stock stroke/bore engines.

No. Don't do that, all it does is create more problems.
-1996 and later V8 flexplates have a symmetrical converter bolt pattern. 1995 and earlier 904s have one offset lug. If you aren't afraid to do it, get out the rat tail file and slot one hole. No way would I ever do that or recommend it.
-If you knock the ring gear off the converter, you will then have to make a spacer to space the starter further forward to make the starter gear engage with the flexplate ring gear. Who knows if that is even feasible, starter could crash with something else.
If I really had to make that setup work, I would prefer to knock the ring gear off the flexplate instead of the converter, and then cut the welds on the offset converter lug + relocate that converter lug so that it lines up with the flexplate. Either that, or have the converter built to that spec (symmetrical bolt pattern/zero balance).
Even better? Get the right flexplate and bolt it together.

The jeep converter I have is symetrical bolt pattern, no slotting required, it all just bolts right up. The ring gear on the hemi flex plate lines up exactly where the ring gear on the converter does on a 5.9 and it is the same diameter and number of teeth.

What intake would you recommend that would work for both? Am I asking for too much from one intake? This will be going in a tube chassis RX7, I'm trying to determine a hood/scoop/intake combo that does it all without too many big changes down the road. thanks for your input
In my case (turbo 5.7 swap into my GTX) I am going to run a ported 6.1 until I finish fabricating my own sheet metal intake.
BTW - I purchased a Torque Plate for this build so if you live close to Pittsburgh and need one give me a shout.

Just a feeler here, maybe I'll start a separate thread once I have this up and running but.....
What level of interest would there be in a "plug and play" or near "plug and play", engine management system to swap a Gen III Hemi into an older vehicle or street rod? There would be several options for this system:
Option 1 -. Complete kit including wiring harness, cable driven throttle body, throttle cable and fully programmable EMS with a base/startup tune already loaded.
Option 2 -The EMS with a base/startup tune and a labeled "do it yourself" harness. Purchaser would be required to obtain a cable drive throttle body and adapt it to the factory or aftermarket manifold of their choice as well as splice into existing harness or obtain electrical connectors and splice on to the provided 8-12' labeld harness(i.e. injector plugs, crank and cam pos plugs, temp and oil press sensor etc.)
Option 2 would be less expensive but require more effort.
I have utilized these systems for many years and would also be available to provide remote/email tuning of these systems if the owner felt the self tuning feature was too complicated or just wanted to squeak out every last once of HP.
Please let me know if there is any interest in this type of system? I have a spare 5.7 truck engine here that I would consider documenting the entire procedure as well as testing it on our dyno if there is enough interest. It is a junkyard "pullout" complete with harness.
The benefits of this system are that you would not need to buy an aftermarket ignition system, aftermarket intake, plug wires, carb etc. You could literally take a junkyard engine, pull the factory harness, splice in this labeled harness, power the EMS and supply a vacuum reference and away you go.
Please let me know your thoughts.
Right now option#2 would be priced around $1600 and I suspect option #2 would be close to $1900 (but this is only a guess based on past experience - I have not priced the Mopar wiring harness connectors and don't know if they are even available....)

How hard would it be to modify the OEM throttle body to be cable driven?
That certainly is an option and I have seen engine dyno shops do this. With option #2 that would be up to the installer of the system. I do have a 5.7 OEM throttle body for sale for $50 if you want to buy it, crack it open and give it a try?

Why not a drag pack intake? They can be bought for under 1k!
Prices for 6.1 intakes can vary from 375-750$ depending on with fuel rails and injectors etc.
Chrysler sells their connectors in a pigtail form, currently not just the connector and terminals. This is one reason Painless said they were not interested in doing an factory efi swap.
Interested in having you car wired? Drag car, street car, EFI swap?
PM for details
