I’ve got a Gen 2 LT1 in a 1956 Chevy, and it has always been a fun engine. It’s mostly stock, but when we put a stand alone EFI on it and significantly improved ignition, we were able to squeeze a surprising amount of extra power out of it. So when I saw Richard doing more testing on his LT1 I figured there was some good stuff to learn. Check out the video below and see what you think.

HOW MUCH POWER DID THE GEN 2 LT1 REALLY MAKE? HOW MUCH POWER ARE PORTED HEADS WORTH ON AN LT1? HOW MCH POWER IS A CAM WORTH ON AN LT1? IS THE LT1 BETTER THAN THE LS? WHAT HAPPENS WHEN YOU REPLACE THE STOCK LT1 HEADS AND CAM WITH PORTED HEADS AND AN AFTER MARKET CAM? CHECK OUT THIS VIDEO THAT FEATURED PERFORMANCE MODS ON THE GEN 2 LT1. IN THIS ONGOING SERIES, THE LT1 RECEIVED HAND-PORTED LT1 HEADS (STOCK VALVE SIZES) AND A TPIS ZZ409 CAM.
