a more exotic swap

imho i would say forget the mitsubihi stuff. ya its kinda mopar but not enough to give up quality. i would look into a different exoctic swap. i personally really like the sr20t motor from the nissan 240sx like what fast and furious did. good reliable motor, endless performance parts, and good power. use their 5 speed and find a good solid irs set up for the rear and throw all that in a 63 valiant and blow people away. in my opinion that would be better then the mits or even the srt4 cuz its set up for rwd. i do think a awd a-body would be killer but havent looked into it much myself. good luck and keep it clean no matter what you do.

o if you stay with '96 or newer you have obdII which is far superior to any obdI system and will save you a lotta headaches. it seems to have cleaner wiring harnesses and better plugs-ins to lol. not a mandatory thing but when the computers got smart i guess so did the designers lol
