I’d be very concerned about the valvetrain. Even though the tires broke free, you likely seriously over-revved the engine (7-8k I’d bet). It’s easy to check out the pushrods, just do it for peace of mind if nothing else.

stock tach is VERY slow, when you do this… 9k+ more likely, the clutch was out

anyone what to do the math. :ohnoes:
