I'm running a 496" 440Source stroker in my Challenger.
Still have the stock un-touched aluminum intake on there, and using Eddy Performer RPM untouched 84 cc heads. Using a XTQ294S Comp solid with 928 Comp springs.
The carbs have had "LOTS" of tinkering to get everything to work well together.
The car will run 10.90's easily and I know there's more in it with some ssuspension work as it has a bad habit of spinning about 20' out of the box on a so-so track.This is 3650# with the driver. so it isn't a light car. I think the 620#'s of torque probably has some bearing on this!
A good roller cam would probably net another tenth or so, and the intake can be ported out by Hughes Engines to their Stage 2 specs. Those intakes actually will flow pretty good for a dual plane if they're worked over.




"stock untouched ALUMINUM heads" What year was that option ???
