Oh, Cuda620's answer....

Copy all the tech onto the engine of choice. Yes, everything is expensive to a mopar as you know but what can you do ?
The after market will charge what the do.

IF you were to go down this route, and yes I know you sold the stuff... my build would/could look something like this;

I would like to use a small block of approx. 360 to 375 cubic inches. How it gets done can vary. But that's the approx. range is like to be in. I do like a 360 stroke in a (probably a .030) 340 block. 372 cid.
The best high flowing cylinder head I could get. I'd like to see at least a 190cc intake size. 220 would be great!

MPSFI IIRC, Edelbrock has a kit for multi point fuel injection though I don't remember if it is sequential. Someone out there has a kit for this.

Small but reasonable size roller cam, I'd go with a Hyd roller. 224/226 on the intake.
Generous header size. I myself would need to test, but, *I think* a good starting point would be 1-3/4 & perhaps stepped into the next tube size. 3 inch piping to the rear.

An overdrive transmission is then must for mileage. The old Chrysler 4spd O.D. is probably the cheapest. And probably, the (supposed) cutting involved would turn most away. I met a few guys with it installed without cutting. (I don't wanna debate it...whatever they did is what they did.)
Then I myself, would supercharge it.
Paxton, TorqueStorm, personal taste on that. Or turbo. Again, personal call/taste.

Reasonable displacement, upgraded equipment, overdrive trans, just like modern cars.

That's what I would do. The cost is the prohibitory issue. And, made even more so by the thousands of engines in the junkyard at 1/4 the age and mileage.

Trust me Ladies and Gents, I don't blame anybody for doing what they do. Money is a big factor. Even more so when you have a lack of it. Builds like I outlined as a possible route are super expensive by compare. We do them because we want to do them.

I'm currently saving for a 6 pack build.
I'm doing an6 pack build because I want to. Nothing more, nothing less, not out to prove a DANM thing by it/with it. Just wanna have fun with it.

There are cheaper ways to make more power but I don't care. Just doing what I want to do before my time is up on earth.
