What do these numbers tell you about your Chevy 350 MH20353 and 10066036?

10066036 is the serial number for your Targetmaster/Goodwrench 350cu V8. The engine was produced in Mexico by GM to act as a budget replacement to rebuilding an engine which could often times exceed the cost of buying one of these.
They came in many trims ranging from 165hp to 290hp and were fitted with 76cc cylinder heads which produced a compression ratio of around 8.5:1, but a few tests have shown actual output to be around 8:1.
They are dependable replacement engines that will run for a while if maintained properly. If you are looking for more power out of it, a dual plane intake manifold, 4bbl carb, some long tube headers and a cam should net you some decent gains.
If you have more money to spend however, replacing the cylinder heads with a
set utilizing a smaller combustion chamber of around 62-64cc will increase your compression and therefor increase power.
