70 AMX - almost yard art status

Good new is that the PF4 now supports altitude compensators...

The smart money would be to just throw a PF4 on and see how it does.
 
Well, being an engineered system is a plus. Pricing it against other stand alone set ups with distributor and all, it's not much more.
I know some of the upper Holley units will control the transmissions. I suspect in time more will add that option, but maybe not at the price point we are seeing

The fact that there are options to go EFI on an AMC engine is awesome though
 
The pricing is great, especially since the last Edelbroch offering for an AMC was close to $4k, the PF4 starts around $1.8k.
Starting from scratch, the PF4 is a hell of a deal.

Unfortunately I'm one of those engineer types that you are so found of. Where's the fun of bolt on and go?
Years ago (20+) 1 modified a Torker with injectors and used "state of the art" EFI system of the day and it never and it never lived up to expectations.

I have a MSD crank trigger modified to work with a GM pcm and a hoard of gm electronics & AMC parts so the initial buy in price isn't a big issue.

Biggest advantage to the PF4 is the lazy factor. Fuel system will be the most complicated part, the rest should require min fab which is nice these days.

As far as the Javelin goes, a 3rd pedal may be a better solution than a computer controlled slush box anyhow.
 
So the engine is looking good and you would likely love the EFI, but I think my lack of AMC and/or Chrysler knowledge is confusing me.

So the 383 is a stroker 360? Is that an AMC or a Chrysler motor? Because I don't see edelbrock EFI for AMC but I do see it for the Chrysler 360, so I'm just trying to learn exactly what motor this is? I always thought AMC and Chrysler were completely different, and now I am confused. I knew there was also a Chrysler 383 which is a like a short deck version of the 440 I believe, but they don't make an EFI for that either. But you guys are talking about how easy the ready to go system is so it must be something they make...

This is a regular 383 Chrysler engine not a stroker
 
I believe his is a small block 360 (LA based?) Stroked to 383. Not a Chrysler 383.
Read the very first post in this thread.

Wow I can't believe I forgot that.
I remember now when I was reading the details thinking who would think of mixing Chevrolet and mopar engine parts and now I forgot because a 383 Chrysler is so common that I always remember not to think it's a stroker

The motor is the original AMC 360 with a 3.53" stroke & 4.155" bore resulting in roughly 382.9 ci.
For the most part AMC V8's are AMC V8's from 70 on. All external dimensions are the same from 304 - 401.
You are also correct, the AMC and Chrysler engines are completely different with the exception of the 0.904" lifter bore.

The part number for the AMC PF4 should be 35650. There's little to no info on Edelbrock's page.
Still trying to figure out the fuel system requirements and how to hide it all.
Any suggestions would be great.

Does tanks plus have a tank that will fit that is baffled?

@beags86 & @imiceman44 back away from the crack pipes. No Mopar parts here. :whistle:
Well you say amc not mopar, AMC and jeep as far as I know are still Chrysler group...
But I understand why you say that because they are 2 different animals.
And if you ever make it out west I still have the 360 AMC, I don't have the patience to list it and I don't like to deal with shipping engines but I am tripping over it

OK, that explains why, it must be a new part number? I was just speaking with Edelbrock at PRI and didn't see it, and I can't find that part number in my price sheet that's about 2 months old or their website. I should of asked if they had the 2020 catalogs out yet when I was at PRI.

Haven't found anything that will fit without cutting the car yet. Re-pop tanks are available so I'll probably just modify one of those.

They are both FCA but kinda like the BOP 455's. same parent company but nothing in common.
Thx for the offer on the motor but I can't see making it out that way anytime soon. If I do, it would be cool to meet up though.

I thought the AMC/Mopar were more closely related then that. But hell what do I know, I don't mess with any of that junk.

Some people just get prissier and prissier. ;)

The 70 up PF4 was just released. Summit/Jegs have them listed @ $1900 with an early Jan ship date.
If I remember right the old PF3 was close to $4k, so the PF4 is much more reasonable and the new intake looks promising.

Yeah the PF4 pricepoint is pretty good considering it has everything but the fuel supply system. It even includes the distributor and MPFI intake and injectors, and everything for plug and play with the engine for sequential multiport injection. Most aren't sequential at that pricepoint, or don't include the actual injectors, intake, and throttle body, it's a very complete system. The limitations are no trans control, no dry nitrous or twin turbo control, and no laptop tuning capability. But for the majority of combinations, it's a very good, complete, simple effective option.

AMC was their own entity and owned Jeep. Chrysler bought them (both) in the early 80s but maintained production of the AMC V8 through the 90s in the Wagoneer.

AMC would buy parts from other manufacturers. Commonly using Motorcraft carbs and ignition systems and Chrysler alternators and transmissions.

They put out some small cars with GM's Iron Duke 2.5 4cyl and 2.8L V6 in the early 80s trying to compete with fuel economy. I have a 904 transmission with the GM bell housing pattern on it at my Dad's house. We were an AMC family for a while.

Dad had a CJ5 and Gremlin X, both with the 304 and he put a 360 in a Spirit with a 904 and 9" Ford when I was little. He had a 401 with a set of cylinder heads from Buck racing engines but we never put it together. He wound up selling off the hot rod to go farming.
