To be numbers matching correct it has to be assembled out of parts that were cast about 14 days from the build date. Then it is just a mater of the block having the last six digits of the VIN stamped on the pad. Otherwise any Chevy engine is correct and any GM iron V-8 is fine (well aluminum ones are ok too; except for the early sixties 231 Buick V-8 that GM sold to Rangerover back in the late sixties).
the cowl starts out 7c. I was told this was a matching numbers car. the vin is 41847s315xxx. I have had it just a short time. Are there any other numbers to look at a verify. If so where...thanks again. Wade
Cowl tag and VIN are it. If you look inside your car you might get lucky and find a build sheet (a piece of paper that instructed the assembly line workers what to bolt onto the car as it went down the line. It was not intended to go with the car (it was trash) but often ended up stuffed into some knock or cranny in the car).
