We’ve had several v10s with catastrophic failure. Personally I’ve had 2. Supposedly there’s a recall on them.Got several v10 Fords. Had a campaign already to tighten loose harmonic balancer bolts. Not sure what mileage they get, but a lot of fuel could have been bought for them with all the money blown on those POS IHC VT365s at nearly 12k a pop. Low 6s seem to be the average for the Chevy powered package cars.
