I bought a 1980 Plymouth Volare Roadrunner clone car from DCAspen. Super guy to deal with. The car, which was originally a Slant 6, comes with no mother or transmission and a 7-1/4" rear axle. The plan is to install a 383 B-Block with Mopar Stage IV cylinder heads which have raised intake/exhaust ports to use a 440 intake. It will be also receiving a 727 transmission and an 7-3/4" rear axle.
