It ain't grey hair, it's chrome!
Perhaps you Chevy numbers gurus out there can help narrow down the year of the engine I just got. I'm guessing it's truck motor, has the HI PERF PASS wording above the oil filter (common) , casting # at the rear 3999289 and GM 1T. Casting #'s on the heads is 346236. The T400 I got with it has the deep pan and bolt on yoke so that tells me for sure it is from a truck.
