69 cuda for 74 roadrunner????

KEEP THE B'CUDA!!!!!
A 74 318 Road Runner isn't a great deal. That da$hpad is about an $800 item, interior trim pieces for the 73/4 B-Bods aren't easy to come by. That 383 is not a bolt-in swap either, K-members were different for small & big blocks starting in 73. Now you need a K-member (or conversion mounts), tranny and possibly rear end to put that 383 in.
Before you load the starter-launchers - I have a 74 Charger so I know the quirk$ these cars have
