the valley area is very thin. i worked on a friends R3 that was ground to much (4 holes to fix) and we had to epoxy the valley. not to big of a deal but still ads to the workload. it's been together for 3 years now with no issues.
i want to feel the massive pull at the top end that a boosted engine has. my car pulls hard but not like a boosted car.
thank you, it's a factory 360 car
