drivetrain

I own a '78 cougar and was wondering if stroking the original 351w to a 427 would be a good idea. also if i should change out the stock FMX transmission for a c-6 and bring the rear end gear ratio up from a 2.5 to a 3.89. Any advice would be appreciated.

dude sounds cool that now i think is a classic. make it nice. you dont see them on the road anymore
