Have you considered a 3rd Gen Hemi? They can easily make to power you are looking for.

Really? They have that? How's it work?

I did actually, and I love those new motors, but I'm looking for a classic Mopar powerplant with this build. I'm planning to buy a new Challenger at some point, probably a Scat Pack or SRT 392, and I don't see any sense in having two of the same motor in different platforms.

I've been eyeing the 426 Chargers, the Daytona R/T 426 has the sweet spot of options for me. I've got some financials to clear up, so next year I'm hoping to pull the trigger on one.

I didn't realize FAST had it but Holley and Megasquirt do. I believe they run a few strategies, the most effective one uses two speed sensors, one on a front wheel on and one on the driveshaft or rear wheel. It can retard timing, reduce boost or nitrous, or kill cylinders to get back to the target slip percentage.

Here is a really cool video of a Megasquirt MS3Pro system working on an 8 second car...on the street. Watch the difference in wheel speeds on the top and the timing down on the bottom on the screen.

Yes, getting ahead of myself I was thinking of the 6.4L

Lol, the 6.4 is a great motor but I'm really looking forward to the rumored 426 Hemi. I may hold off on buying a new Challenger until it's confirmed or debunked.

I installed an all-aluminum 426 Gen 3 Hemi in my E-body in 2015 and have been tracking it ever since. I'm a dealer for Prefix Performance who builds similar race engines for the TA2 series as well. In my opinion an all-aluminum Gen3 is a great compromise with small vs. big block and super reliable 500 rwhp. Save your pennies though as they are not cheap around $20k

My advice, as I have been there before with my `Cuda, is to make a solid plan and to not deviate from it. I also had intentions of putting all the latest tech in my car but that eats up any budget fast. I was going to replace the `Cuda's 340 with an all aluminum 572 Predator 800hp engine but all the custom fabrication made it that if stuff broke great expense and wait times will mean less seat time at the track where it matters and most importantly having fun, the most. In the end I was able to sell my Predator stuff at about 75% of what I paid and saved enough for the 426 Gen3 Hemi that had just been released at the time. I build for reliability & durability, to me they are more important than horsepower.

I was enlisted in the USMC as well and being in the military will allow to to save up a decent budget if you are smart about it. Have fun!
