What is the biggest motor you could put in one?

 

318 was biggest stock motor, a 440, 426 hemi etc can be made to fit. a scamp is a dart with a duster nose

 

my old brain seams to tell me that chrysler put a 383 and/or 440 in 68 , 69 a "A" body. IF my brain is right. this does not count the 68 HEMI CUDA 426 hemi. THE fastest stock car ever. only 50 Cudas, 50 Darts was made. but NHRA lets you MAKE one out of a reg barracuda.
