It's because everything isn't shitty from there.
My 493 stroker kit came from there. The crank was checked and needed no correction. The rods weighed what they said to the gram. The big end was correct OOTB. The small end was honed to size for the pins that came with the Ross pistons. My machinist's idea of close enough is measured in ten thousandths of an inch.
Now their Comp Pro Magnum knock off rockers were unusable OOTB and by the time I corrected all their problems I could have bought the real thing and been still using them. Yep they died.
That being said while all the other vendors are still selling the same basic piece of crap rocker, Brandon took his off the market.
Now those Ross pistons didn't hold their expansion tolerance for their piston to wall spec and are now scuffed slightly.
The Edelbrock heads came with a Briggs and Stratton valve job and the MP M1 intake came nowhere close to fitting OOTB. It took .070" to get it to fit properly. It only took .007" to zero and square the block so was it the intake or the heads that were FUBAR?
As far as I'm concerned, China doesn't come close to having the poor quality control market cornered just yet.
