Hey all ran into kind of a stumper. I have a 1970 C20 Camper Special longhorn, I was going over the numbers on my engine trying to see if it was a 2 bolt or 4bolt main but the numbers i find are coming up with a 262 the title says the engine is a 350 and so do the emblems on the side of the truck. Well here are the numbers I found any help would be apriciated.... 1st T0522CZT 2nd 152162665 and 3rd 355808 or 355909. Thanks.

Welcome to the board from south Mississippi! Where did you run the numbers? I usually use www.mortec.com

It also shows as a 76-79 305 using 355909. That's the beauty and the trouble with GM making a ton of different engines using the same block. They can be swapped with no trouble and you can't look at them and tell the difference.
