VIN for CID
Chris
The eighth digit of the VIN for a TPI 305 car is "F"
The eighth digit of the VIN for a TPI 350 car is "8"
The only differences between the two are PROMs and injector flow rates.
The 350 uses 24 lb/hr vs the 305's 19 lb/hr.
If you see a VIN "E", that is a 305 TBI.
If you're at a junkyard though and you're going to see the motor before you buy it, why does the VIN matter? People swap motors in those cars ALL the time. I swapped my TPI out for LT1 heads/intake, and then swapped a 350 under it later on. My VIN would have told you it was a 305 TPI car. My buddy put an L98 (350 TPI) into his car, but the VIN said it was a V6 car (originally).
If you know what TPI is enough to be looking for one...I imagine you know what one looks like..
