Head casting numbers?
« on: August 19, 2007, 05:48:47 AM »
I have a 69 with a 350 which is not original to the car. So far I know the block casting number 3932388 could have been in a late production 69 Camaro. The intake manifold is 346250 GM 4 which is for a 76-83 305/ 350 next is the heads, where do I find the head casting numbers, under the valve covers?

Correct.  The cylinder head casting date is located there too.

The 388 block is more of a mid year than late year block.

The car is a late production car by the numbers and I know by the vin, cowl tag info and the POP which I was lucky enough to get was built with a 307, PG, non posi 10 bolt. I'm just trying to figure out what the 350 engine that is in it now was built with.

Thanks for the pic John.

The casting numbers are 3973370, small valve replacement heads.
