Casting numbers and questionabout TPI
I wrote down the casting numbers on my engine today just for grins, can anyone tell me about them?
The number on the back of the block is: 3970010
on the front of the block, passenger side: E3314 9 5(?)
Head casting number: 3927186
Engine is supposed to be the L46 (350/350)
Second question:
I have a line on a TPI off a L98. The upper/lower intake, throttle body, computer, wiring harness, fuel injectors, fuel rails, HEI distrubtor, egr. Would this work on my block and heads? I heard that I might need to modify the intake center bolt holes to make it fit. Anyone have any experience with this?
Thanks in advance

I think it's GC, it's very faint. Is that all there is supposed to be on the stamp pad? GCE3314 9 5? Or should there be more?

As an example the code should be something like V010HY. The letters come at the end of the numbers. If CE is followed by a number then it propably is a replacement block.

Steve- thats all there is on the stamp pad. I think it is a replacement block, which is fine, I was gonna modify it anyway :D
