The Stovebolt Site Forums Welcome! Welcome Centre Chevy 6 cylinder identification

Hello everyone,
I enjoy reading all the posts and answers but have not seen anything to help me out here. I have a 6 cylinder that I removed from a 1941 Chevy AK. The flat spot behind distributer has the numbers 05I0868 F54Y stamped on it. The casting number is CON 4 D84. Can anyone help me identify the year on this. I think it is a 235 but can not seem to find any numbers to match. Really appreciate any help anyone can provide.

Welcome Dave, I'm sure someone here has the answer. Either check the tech tip at the top of the page, go to identifying your truck. Otherwise ask in the engine forum.
Leo

OK Thanks.

Welcome to the Stovebolt, Dave. I know just enough about identifying engines to be dangerous so as Leo mentioned ask in the engine forums. Some of the guys there know it by memory..... there is also an online engine manual link here on the bolt that lets you read it first hand. Good luck and you join other bolters from Iowa so watch for them.

05I0868 F54Y stamped on it.
F54Y = the Engine Serial Number
F = Flint, MI engine assembly plant
54 = 1954
Y = car 235 with RPO 313 (Powerglide, 2-speed, automatic car transmission)

The casting number is CON 4 D84
This not the block casting code, it is the block date code:
CON 4 = Conveyor #4 at the engine plant
D = 4 = April
8 = 8th
4 = 1954

Thank you very much. I appreciate the info.

54 Passenger Car Engines with manual transmissions had solid lifters.
Read under Tappets, Hydraulic valve lifters --- None.

54 Passenger Engines with RPO 313 (Powerglide transmissions) had Hydraulic valve lifters.
Automatic transmission option, Hydraulic valve lifters
http://chevy.oldcarmanualproject.com/chevyresto/5448.htm

Those Hydraulic valve lifters engine blocks have oil passages drilled into the block to feed oil to the Hydraulic valve lifters.
Where as the engines that had solid lifters did not have the drilled oil passages.

I believe the benefits of Hydraulic valve lifters is to maintain zero valve clearance and the engine runs quieter.
Conventional solid valve lifters require regular adjusting.

I would say the reason GM used hydraulic lifter engines with the powerglide transmission was because it added more luxury.
If you forked out the money for a powerglide transmission you got more than just a automatic shifting transmission,
A. Less engine noise in the passenger compartment.
B. Less engine maintenance.

What was the reason why you pulled it out of the 1941 Chevy AK ?
If the block is still good it would a good engine to rebuild.
