68 charger 392 or Hellcat engine???

[Roger Cox]

Can’t decide.

Already have a ton of money in the build, paint and body, QA1/Gerst front rear and rear coil over kit.

TKX trans.

I like the idea of the hellcat engine, but worried about having AC condenser, Heat exchanger, and oil cooler mounted in front of the Radiator and causing heating issues.

Goal for the car is not to race, but for long distance road trips, and fun around town.

Go hellcat Helliphant and dont worry about heat.

Haha I think Redeye would be the most my Moser Muscle Pak 8 3/4 could possibly handle.

You don’t think they’ll be heating isssue with hellcat engine?

I have Griffin Rad with their largest dual electric fans I had for another project.

It’s very hot where I live , summer Gets 100-105 and want to be able to drive for 4 hours and not worry bout anything.

You will be fine nd go with the badest and you will wow the crowd

 

[Roger Cox]

Yeah I’m only going to do this once so might as well put the hellcat engine in I guess.

Where’s the best place to mount heat exchanger?

And anyone with a hellcrate swap in a charger have any heating issues?

 

[Beekeeper]

Unless you plan to do hard launches from a sticky track that 8.75 will hold up just fine.

 

[Roger Cox]

I guess my biggest concerns are

- where to mount heat exchanger and oil cooler. Which heat exchanger unit do I need.

- keeping engine temps down with so much restrictions in front of the radiator

 

[snakeoil24]

Use all mopar designated parts in their program

Keep the grasshoppers out of them.

Thought I would add some photos - got some epoxy primer on today! Def going hellcat engine..

[Roger Cox]

should I use Holley Terminator X with holley harness or buy the Mopar ECU? You can tune the Mopar ECU too correct? (Long tube headers)

 

[snakeoil24]

Everything mopar

 

[snakeoil24]

You can salvage a complete harness and controls from a good yard otherwise Holley is the only other

Electronics cost is a wash either way if you get the OEM stuff. Hotwireautos harness and tune aren't cheap

 

[snakeoil24]

I would send mopar harness and eco to bills performance in Maryland great work and save a ton.

I got a dealship quote for $2265 for (77072452-AE), and comes with Warrenty so I’ll probably just go that route.


This is the PWM for fuel system I need right and it comes with the harness to connect directly to ecu yes?

What trans are you using?

 

[70chall440]

Holley Terminator Max X would be what I would use (and am using in my 71 Charger 5.7 build). Very tunable and well thought out, will support boost as well.

Nothing like getting paint laid down. Looking good. Did you put frame stiffeners on the car when building it? Going with that much motor in the car have you done anything with the suspension. Just thinking out of the box. Have a good one and keep us up on the build.
