I've got a factory big block Challenger & a factory 340 Challenger... Honestly the 340 is a better driver... But... It has a 518 O/D trans & 4.30 gears... So it scoots outta the hole & goes down the highway great... 4.30 with O/D acts like 2.94's.... If I were to do it again I'd probably use 3.91's...
Currently I'm helping a friend do a Gen III Hemi swap which I'm sure will be awesome but I think the 340 is my preferred choice...
Your wife has a Super Cool Challenger!! Congrats on your retirement!! Have Fun!!!
Oh, FY1 Bright Yellow looks great on Challengers, especially with so black accents...
