I know all the drive train has been replaced (except maybe the driveshaft!) the differential was replaced before I bought it, the column shifted Powerglide was replaced with a floor shifted TH350, and the 'supposed to be a 350' is actually a 305. Is there any way to determine which engine it came with? I'm assuming probably a small block with the powerglide? I think I have the original fenders, which had all the trim holes iced over before a lackluster red paint job, so any help with fading preserving the numbers is probably gone. I can't see from the inside (yet) where the original emblems were, did all the size emblems have the same mounting? I don't know if gas line diameter will help, as it has about 4 feet of rubber at both ends, and the fuel pump is after market with a barb on the inlet instead of being tapped for a fitting. Exhaust is a home made single setup. Any ideas?
