Just came across this video of an LT5 with velocity stacks on an engine dyno that the poster says was spun to 9200 RPM.
Maybe you guys have seen it, but I thought I'd post it anyway. Here is the info on the engine that is in the description:
"LT5 C4 ZR1 engine spun up to 9200rpm. Engine was built by Bonefied Customs and runs Bigstuff3 as the management system. Made 550hp and 450ftlbs at 8500rpm. Engine was destroked to a 5.0L to run at the Bonneville salt flats in the D/GT class. Enjoy!"
Why did they need to destroke it to run at Bonneville? And I thought the timing chains couldn't handle RPMs much past 8K?
Wow, what a sound! Crank up the volume...
