is this true about a 350 sbc vs a sbm

His 350 probably was Balanced & Blue printed, 3/4 race cam, 6 inch round air cleaner to show off his painted vacuum secondary holley and a auto zone chrome kit.

don't forget the Holy Grail of the chevy engine- it may be a 'corvette engine'.

Like that's supposed to be a bonus lol.
