Holley built this 1979 Pontiac LeMans for part development. In the engine bay they swapped a 4.3 L LV1 V6 (EcoTec3) capable of 285 hp and 305 lb-ft of torque. The all-aluminum motor features a modified LTx oil pan, modified LTx exhaust manifolds, Holley LTx mid-mount accessory drive, and Hooker Blackheart G-body exhaust. Holly paired the V6 with a T56 Magnum six-speed manual transmission. From there power is sent through an Inland Empire driveshaft to a 10-bolt rear end. To improve handling they went with a Detroit Speed Front Speed Kit 1 and Rear Speed kit 2 featuring tubular control arms, Bilstein shocks, lowering springs, and sway bars. Would you be interested in using a LV1/LV3 in your next swap?

This is perfect! I’ve been waiting for these motors to catch on.
I’d love to do this swap on a 1st gen S-10 or Blazer.
How much weight was lost with the 4.3L LV1 V6?
Very interested in this powertrain (LVX/Manual). Did it ever make it past “development”?
Yes, I would, but SOMEONE won’t start making the parts for it. Come on Holley, at least make the intake, and make it with port injection bosses!
