Default Engine Code



Trying to solve a mystery. The engine code is clearly V06"I"8HT The I being a capital letter I not a 1. I know the V is for Flint, 06 is day, HT is for 350 HP high performance. But the I ,,,, If it was 18, then maybe 6/18,,, June 18, but then there isn't a year. I guess the year is in the other number stamped on the engine, 186423359. So did Chevrolet run out of the number "1" stamps?
I have nothing else to do today.

Yes, GM used I's for 1's. Rather common.

On the VIN are you sure it is 186423359 and not 18S423359? If it is an"S" it is a 1968 HT 327/350 VIN would be 194378S423359.

I think you are correct. Kind of hard to read, but it is an S. Matching numbers car.
