·I am looking for 67 GT-500 experts. This is fairly involved , so please bare with me. My brother is looking to trade his 70 Boss 302 for a 67 Shelby. He wanted a GT-350 , but as many of you know they are harder to come by then the 500's. Anyway , he has a potential trade lined up , but there is some question as to the authenticity of the engine in the Shelby. He told me that the owner states that ford ran out of 428 PI motors at some point and had to resort to putting 390's in some GT-500's. So , if this is indeed so , how do we find out if this car originally had a 390. He tells me that the GT-500's did not have the serial number in the block , so there is no way to verify if this is indeed the correct motor. I asked him if this was a 4 speed car , he said yes it is. I know that 70 428 cars had the serial number stamped in the trans. case. I am assuming that shelby's did also. I asked him if the trans. had the serial number stamped on it , he said it did. My thinking here is that if the trans is a small spline top loader then the car did indeed have a 390. If it is a big spline top loader then the car should have a 428. I know that it is possible that someone could have changed the input shaft from a big spline to a small spline and thus kill my verification theory , or even swapped the trans. case. Anyone have any ideas on how to verify if this car should have a 390 or a 428?? If the owner is trying to get rid of this car with a 390 instead of the 428 the car should have this could be a major issue in the value of the deal.
