Super Dave's Classic Car – Info, updates and upgrades for GM Gen V engines

ZR1 Top Speed Run at Papenburg

Watch closely at the 0:40 second mark when the transmission shifts down 4 gears from 8th gear to 4th gear, the direct injected engine revs almost instantly. Same bottom end as the LT4, just a bigger supercharger gets you another 100 hp. Ligenfelter has pushed the LT4 engine up to 1,400hp with the stock bottom end.

Here’s the latest info and updates on the father of Pro-Tourings latest effort that was unveiled at the 2017 SEMA show. Check my previous post here.
Unlike my build, Mark chose to use the dry sump version of the LT4 and managed to hide all the plumbing and sump inside the fender well. From what I’ve read this is just the starting point because he’s planning on boosting performance, so stay tuned.

They’ve taken the LT4, beefed up all the internals and added a much larger supercharger with more boost. You can also see from the top of the engine that they’ve increased the intercooler size substantially. This engine is much taller than the LT4, which will present a challenge for engine swaps.

Gen V L83 Truck Engine Swap

by desmodave • December 15, 2017

More and more L83/L86 truck engines are available now from wrecking yards at reasonable prices, some including the 6 speed 6L80E transmission. These are great solutions for drive-train swaps because they are plentiful, powerful, priced far less than the LS3 and Gen V LT1 takeouts and come complete with everything you need. ICT Billet has just released brackets that allow you to easily add hydraulic power steering to these engines. Reference my installation guide for vendors who provide reflashed ECUs.
