trying to identify my engine PLEASE HELP?! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Thomlost · 06-26-2011, 09:01 PM

Here's an attached picture of the numbers I found on the front of my block... My main question is do I need all of the numbers to find out what year, etc. about my engine?? The bigger ones are pretty easy to figure out (V0603TYY) but the smaller ones to the left it looks like there's possibly two sets looks kinda like 5Z and 729... I'm really not sure if it's a "Z" and if there's any numbers in between the two sets that just happened to come out lighter and it's really one big alpha numeric number... if I zoom in on the picture it kinda looks like 5Z157729 but the 157 in the middle are really really light and my eyes may just be playing tricks on me... so yeah any help would be greatly appreciated!!

Look on the drivers side near the bell housing,there should be a casting number,then you can derermine what you have.

From the book I have that (TYY) engine code comes up as a 1975, 1976 and 1977 350 with manual trans. Hope this helps. Scott

Awesome!! Thanks!! Looks like I'll be crawling under it tomorrow to find that casting number!

Thomlost, Check out the website bollybib gave you for the location of the casting number and date code. You'll be going over the top not under it. Casting number is on top at the back by the dist. Date code is on the other flange at the back by the dist.

Your engine came out of a Truck C10 or C20, 75-77

Looks like a 350 out of a '75+ truck. The small numbers and letter matched the VIN on the original vehicle. Z=Fremont
