502/502 engine for sale

[Tjwong]

I have a fresh Gen 6 GM 502/502 engine for sale with GMPP signature series aluminum heads. The engine is totally balanced and blueprinted from a well known and respected machine shop in Portland Oregon.  

 

This 502 is better than new OEM GM specs, pistons were replaced with new hone to fit JE forged pistons using a standard tension ring pak. Contrary to belief all production 502's including the latest GEN 6 engines are still being produced with GM's proprietary GM/JE piston that utilizes a metric low tension ring pak, and will have high oil consumption. Which is OK for a weekend cruise or race car. However it is not acceptable in a daily driver.

 

This 502, depending on camshaft, valve train and induction choices will yield between 500 and 610 Hp. With the block, piston and head combination this engine yields a true 9.6:1 compression ratio. A production 502/502 advertises the same 9.6:1 when in reality it can vary from 9.2 to 9.7:1. Depending on deck height and chamber volume variations.
