Looks like a new complete engine management system will be hitting the market for us hemi swap guys. It will include a sealed box built with a MS3 board, and will come with everything needed to get the car running (cable throttle body, complete wiring harness, etc).
Alex and I will be testing some of this for the developer in the next few weeks/months- I'll update with progress as I have it.

I'll be stuffing a 5.7 in my '73 Dart, but will not give up powersteering! For that to happen however I need to switch over to a power rack&pinion system. A Megasquirt3 will be controlling the motor. Fuel will be LPG fed through vapour injectors. Not sure yet how the Hemi will interfere with the brakebooster. Behind the Hemi will be an A518 overdrive transmission.

I will be attempting factory power steering with headers I weld.
My 73 duster brake booster does not fit. Too large of a diameter. An early a body booster fits, but finding one is the problem.

To be honest, your pics on your website made me decide I had to go with a R&P steering. I could have a go at welding my own headers as I've done that before, but the room available just seems to tight to make a nice radiused bend. But please, prove that wrong, so I don't have to go through the trouble of installing a R&P aswell for this #$%@!# Hemi...

You just need a 72 and older booster.

I *think* that's a smaller booster diameter than I have.
As far as the headers go- #3 is the problem. #1 and #5 will be tight, but the turns should be fine. I may just have a poor flowing #3... We'll see.
How tight is too tight of a radius for headers? Does anyone know? For 1.75" tubing.

I would run the 09 Eagle 5.7 in place of a 6.1 head any day of the week on an N/A build.
What is the reasoning behind this statement? And I am asking just because I dont know the differences between the two.
The only reason that i know of is the smaller closed chamber. The 6.1 is a larger chamber however it does flow more and you can make more power with it. However the 6.1 stuff is harder to find and cost more IMO the Apache head is the hot ticket

I wish someone would design headers or at least attempt to build around a passenger side starter setup to allow us A-body guys to maybe use power steering without springing for an Alter K or equivelant. I also think it might allow a person to use some SRT-8 manifolds from a Jeep or Challenger? Just curious if its been considered and/or already ruled out as effective.
Mopar to the bone!!!

I don't have the k member and motor out of the car currently, so measurements may be difficult. 2" less is prob a good estimate. I know the jeep grand Cherokee manifolds fit with the manual steering box, though.
