When we got the LS1 out of a 1997 corvette we had no idea how many miles it had. Hell we didn't know it even ran. We told the guy selling it on craigslist “when you show up with the motor we’ll test is and then we’ll decide to buy it”. This was a bluff. We assumed just by showing up he knew the motor was good. We slapped it in the Miata and ran hard for the last 5 years. Needless to say it’s time to rebuild it..
We took some time to figure out a simple issue. How do we keep engine oil out of the back seat of the jeep? We bought a harbor freight trailer and built an engine stand that will work with the trailer.
Finished up and the motor delivered to john’s shop in TN.
John was filtering in photos from the build.
The skirts are scraped up.
A little nick from the valves on the piston. These pistons are not going to work. The vales should be replaced too…
|John removed the old beat up pistons. The early ls1 cast
pistons are huge and weight in at 578.7 grams. |
Our new pistons are a lightweight when compared to the old ones. These Probe pistons come in at just 498.0 grams. A savings of 80 Grams
Johns going to have some fun pulling 640 grams out of the crank.
