440 4-5 speed or OD auto? 440 alum heads, intake, water pump, should get to small block weight 383 as well?.....keep it simple...keep it real (within your budget) then just drive it!
An upgraded turbocharged SRT4 engine hooked up to a 904. A couple members have started some threads on it. Some are trying to utilize a Chevy MA5 transmission.
Here's a different one, get a junked Pentastar V6 out of an Avenger, Charger, or Challenger, or even a 300, THAT would be different but would probably be a fabrication nightmare...and you'd have to turbo it to get the power level your looking for...
