327 L30 Intake Manifold date

[67rs327]

Q for the group:  Would a casting date of "I86" (Sept) on the intake manifold of a '67 11A LOS  L30 build be too far out of range?
Looking to determine if I have a transplant.
Thanks-Chris

It's a llittle beyond what's "typical", but certainly not out of range; if it was on a Corvette, it wouldn't get any deduction in NCRS judging.

I've got an 11B L48 from LOS with early H/August casts and an engine assembly date of the 19th.  Sat around nearly 3 months.

Thanks for the feedback. I'm going with its good!

I have an 11B '66 (Norwood) convertible with casting dates of H6 intake, heads, and block.  I don't have documentation such as protect o plate, build sheet, or original invoice, but the engine is a 10/22/66 MM assembly stamping which is a L30 with powerglide. 

I also have a friend who's grandmother just left him her 1967 Impala (purchased new and built in February of '67), four door, no power, no air, L30 (327-275) with powerglide.  It has casting numbers of H-16-6 block, H-16-6 heads, and H-16-6 manifold, I know........ unbelievable!!  (for a March 1967 Impala)  The block assembly stamping is so rusted that it's non retrievable - believe me, we have TRIED.
