It is a passion for me....I really enjoy it.
I hope you weren't being sarcastic when you were talking about the value added money with the clearance/spec sheets, etc.
It really does mean a lot since most mass rebuilders don't take time to actually measure bearing clearances with mics/bore mics, mix/match bearings if they have to, double check all the machinist's work, etc. You also have to realize that a lot of the times they don't advertise EXACTLY what parts are going into the engine, just so they can shop different manufacturers and get the best deal at the time.
My engines also come with RAM flywheels, good harmonic balancers, internally balanced, etc, etc. ARP fasteners are used everywhere internally, down to the cam thrust plate bolts,
oil pump bolts, etc. You won't get that from Ford.
