Thread: Chevy engine ID

Tweet

I bought a SBC 350 engine for my Mud Truck. But I'm not sure about it, The number stamped on the Passengers side of the Block behind the Alternator is 16S406771 V0923CHC Does anyone know how to Figure out exactly what engine this is. I have looked online for sites Posting engine number but can find or figure out the ID. I was told from the person I bought the engine from that he thought it is a 4 bolt 350 from the 70's or 80's , it does have 202 heads, and a 500 something lift cam ? Elderbrock manifold and Elderbrock 600cfm carburetor.

CHC suffix has SEVEN possible origins
Camaro 78 350ci, 175hp, 350 turbo engine code LM-1 4bbl carb
Camaro 88 305ci, 220hp, 700R trans, LB-9 tuned port injection
Chevelle 73, 307ci, 115hp, 350 turbo, L-14 2bbl carb
Corvette, 75 or 76, 205/210hp 4 speed, L-82 4bbl carb
Impala, 80, 350ci, 190hp 350turbo, LM-1 4bbl carb

Thanks for answering my post, looks like I still need more info ?

Here are a couple of sites
Small Block Chevy Engine Block casting and code identification
Mortec - Chevy Small-Block Casting Numbers, Engine Codes and more
Chevy Casting Number identification - Block casting numbers
Small Block Chevrolet Codes

Generally, you would start with the casting number off the rear of the block. This is a 6, 7 or 8 digit number that is raised from the surface of the block, cast right into the block material. It is on the driver side, just forward of the back face of the block where the bellhousing bolts on. It's usually gunked up with grease and debris, so that it will take some cleaning with solvent and a toothbrush to be able to read it. Once you have that number, you would fine tune it with the suffix number off the front of the block that you have provided. Once you know what the block is, remove the valve covers from the heads and find the head casting number in between the valves.
