Intake Codes

[Jim K.]

Sorry to be a pain with codes but, can anyone help me with the following codes on my intake:
It's a cast iron 1x4 with D202 (date code??); GM1; 2-2-81; and either
3788849 or 3788349 or something close 8's, 3's, 6's & 9's seem to all look alike in these castings!!!! I'm hoping for a 61 1x4, but I'll be happy as long as it's healthy!!! Thanks!!! Jim

Re: Intake Codes

D202 is April 20th, 1962. For a late 61.

Jim -

Looks like it's a 3799349 (if it doesn't have a power brake fitting boss cast behind the carb pad on the #8 runner), cast April 20, 1962 (they all had 2-2-81 cast in them, doesn't mean anything). It's for an AFB, and was used on '62-'64 300hp engines; the casting date says it was used on a '62. The Spec Guide incorrectly shows it as aluminum instead of iron for '62, and correctly shows it as iron for '63 and '64.
