just finished putting together an e-m with ho 351 and corvette suspension. few comments overall all fit and finish is excellent. few minor problems that i ran into 1: radiator bracket was upside down and not noticed until i had trimmed some inside fender fiberglass. 2: it has 2 single roll bars that i installed, the three small holes for each of the roll bars in the delivered body were not in the correct position, this was only discovered after drilling the fiberglass for the roll bars!!!.
other than that, no problems with chassis and body. i bought frame and engine assembled and body about one year later.
engine was built by southern auto and had 2 nuts work loose and wound up double nutting all.
also am looking for an upgrade on the disk brakes, am not used to " no power brakes"
overall, a little expensive but worth it
