Installing Chevrolet & GM Engines



gm_ls6_thumbTrends with Jeeps come and go, but engine swapping is the steadily rising constant, and today, conversions in Jeeps are done more often than in the hot-rod glory days of decades past... and these conversions are done cleanly and with greater success than ever before.

Based closely on the CJ6, these Jeeps have swank and style, but many of them need some motivation.
