Default Identify camshaft

I pulled my 400 apart. How do I know what cam size this is? Numbers on front of cam are 911324 and 204 .on side of cam are 1805 GMC. Any help? Thanks, Dan. Also looking for a 400 Bare block. Mine has a crack on a cylinder. Or poss. a 428 shortblock.

It sounds like a auto parts replacement cam. I had a cam I had a hard time IDing. The advice I got was to take it to a machine shop and one of the machinist id it for you. Thats how I figured mine was a replacement stock cam.

Take to a shop that has a cam Doctor, for 20 bucks they'll
tell you exactly what you have for spec.'s.
The things they hide, the way they spin things, the excuses that they make and the things they omit.

Default Cam#'s

That sounds like an original GM cam part# for a Pontiac.
are you sure that pair of 1's is not a pair 7's
If you know the year of the car the engine came out of and have the engine id code that is on the P side front of the block on the ID pad you could query a dealer if they still have the old part #'s saved or possibly one of the internet database sites for Pontiac part #'s.

teufert.net had a lot of those part #'s on it.
Or just have some one with a cam checker look at it.
If you are rebuilding the engine put a new stick in it.

it looks one # short of a Pontiac cam.

9779068 = 1965 3-2s or 1966 3-2s or 1967 400 HO they used this cam all the way to 72

I did not find a 911324 or a 977324 in my books
