LS-swapped Porsche 😈

Wow, this car is soooo much more fun to drive now! I’m really happy with this swap, I was able to keep all the factory gauges working, and the gas pedal- which I had to combine Porsche and GM gas pedals for fitment/function for the drive-by-wire throttle. The headers and modified factory mufflers keep it sounding Porsche-ish.

5.7 LS6- cam, ported heads, 92mm intake, 180-degree headers , modified factory Porsche mufflers

Probably the coolest sounding car to ever come through my shop… C8 Z06 with Valvetronic exhaust 🤯

Final assembly on the LS6-911 swap. Wrapped the headers and finished up the mounting brackets. I thought Chevrolet Orange was the most appropriate color to paint them 😁

This is going to be one bad truck 😎

This GT350 has had a ticking noise in the engine for a while. It sounded like an exhaust leak, so I pulled the header off, and found a crack at the fl**ge. But after repairing the crack, the noise was still present. I pulled the valve cover off and found a collapsed cylinder 7 intake lifter. One new lifter and rocker arm, no more ticking noise 👍🏻

Here’s the Redeye with mid muffler delete. This mod is a great option for owners wanting to add a little more volume to the exhaust note.
