The torque from the 440 can be meaty down low, and doesn't have to be a high revving monster to get good power all in around 5500 rpm. Engine Masters dyno'd 440 built to go back in General Mayhem, and it made 564.2 ft/lbs @ 4100 and 536.1 hp @ 5600. Nothing exotic, forged crank, did go with aftermarket rods with the .990 pin size, JE pistons, a hydraulic roller cam 244/244 duration .555 lift 110 LSA, Stealth aluminum heads, Mopar RPM Performer intake, Holley 830 CFM HP on a 1.5" spacer, and 1 7/8 headers (good luck with truck headers). Not a lot more than a regular build, and it's in the safe zone for RPM range that most people will use. Heads are $1100, the intake is a few hundred, the cam isn't cheap, the lifters are $560. So even with smaller tube headers (1 5/8 tti shorty's made 540 ft/lbs and 500+ HP), you're still going to have an engine that will pull hard.
The modern Hemi can be dumped in with a carb intake and you can lose most of not all the sensors depending on what transmission you choose.
I'm building an RB, because that's what I have, I've had most of my engines laying around for years, waiting for me to build them, and it's finally getting close to that time.
Good luck with the build, keep us posted.
Now, where are those pictures?
