Someone told me it was a V12 truck motor based on a early 305 V6 GMC. not coupled but an actual V12 block tied to a Toronado drive. I checked it out but couldnt get past the motor. Like the 305 it had the spark plugs on the carb side of the head....Really neat . The only problem with the Jalopy Showdown, is theres too many cool cars there,,,,Those boys from long Island sure can drink ....
