84-85 13B 6-Port Engine Numbers

Main Engine Page | Home Page


These are the Part Numbers for 84-85 13B 6-port Engines, -- the engines in the 84-85 GSLSE. These are just the majority of the ones we list. We are able to "build" about any combination possible with our computer -- just give us specific requests, and we can come up with a pretty exact estimate of the cost.

The "Build Level" chart is at the bottom of the page

Note: Core supply is variable, please call prior to ordering your engine.

Note: For 84-85 13B GSLSE engines, the cost of a full gasket set is included in the price of the engine. We use the gaskets/seals needed to assemble the engine, and send the remaining ones with the engine - that way you have essentially all the gaskets needed to finish the installation.

Note: The 89-92 higher compression / lighter rotors can easily be installed in the 84-85 "C" level (and above) engines. Extra cost is the price differential between the two pairs of rotors, + cost differential of the 2mm vs. 3mm rotor kits, + front and rear counterweights (for the rear, it is easiest to just add a light flywheel as these come with the rear counterweight - we will substitute the correct rear counterweight). As of 3/13/02 this extra cost is $569, which includes a $372 light steel flywheel.

Note: ALL Engines have NEW Apex Seals, NEW Oil Control Rings, NEW Corner Seals, New Side Seals, ALL Springs are NEW, All Gaskets and "O"-Rings are NEW, with NEW Front and Rear Seals.
