69 396 exhaust manifold casting numbers needed

I need to replace my manifolds. .I believe drivers side to be from 73(3994045).....and passenger side to be correct, 3916178. What are the correct casting #s? ? I found #'s on nasty z28 but they only list cars. My block is dated 10/68

Thanks in advance, Rich

Re: 69 396 exhaust manifold casting numbers needed

No idea what the casting numbers should be but are you sure those aren't actually the PART number cast into the manifold?

If so, 68-70 396:

Left Hand: 3914617
Right Hand: 353028

That part number is used across a number of platforms. I have a new spare somewhere, just not sure which side I have!

3914617

Chev. Pass. 1968-69 396
Chev. Pass. 1968-69 427
Chev. Pass. 1970 454
Chev. Truck 1968-69 Convention Cab 396
Chev. Truck 1970 Conventional Cab 400 (aka 402)
GMC Truck 1968-69 Conventional Cab 396
