Since your replies always come with a sense of attack towards me, I'll have to reiterate the following point:

My data is actual first-hand data, coming from measurements, testimony, etc., from either myself or customers.

Your data is based on "the opinion" of others, the Summit Racing shipping department, etc. How can that be valid? You yourself said that we need to distinguish between opinion and facts, but yet I never see any facts.

Also, if the block fails, how can the bellhousing be at fault?

If you clothesline yourself riding a motorcycle and your head pops off, is it the helmet's fault?
