Hello from BluePrint Engines!
Do you actually check and record bearing clearances??? Plastic gauge or micrometers???
Do you "degree" the cam to make sure it's properly positioned/clocked to the crank??? Verify the valve open and closing are to the manufacturer's spec???
Piston to Valve clearances???
Is all of this recorded and given with the engine???
All valid questions! thanks!
Every engine we offer has a VERY extensive BOM (Build of materials) where bearing tolerances, cam degree specs, torque specs, etc are noted.
This information is all recorded and kept for our records. We will give this information to a customer if they request it.
Q: Do we degree cams on our performance engines?
A: Yes, we degree the camshafts to spec on our engines.
Q: Do we check bearing clearances?
A: Yes. every BOM has bearing clearances that must be met. Since we're doing everything in house there is less initial deviance when we control that part of assembly. Our facility is brand new, and we have CNC, laser measuring, and of course the manual measuring you have mentioned (both mics and plastigage) . We don't just throw them together...these are checked meticulously with everything from mics, to laser scanning in QC.
Q: Do we check valve and piston clearance?
A: Of course. Lets remember. These engines are designed to be streetable, reliable, and provide the best longevity and horsepower per dollar in the business. We would never produce an engine on the "outer limits" of piston to valve tolerances.
We're a company that cares about our customers, and provide a reliable performance engine we stand behind. I'm going to post a short video below with our facility shown. We're capable of punching out 50 engines a day. Let that ease the mind that these BOM's are long thought, and designed for longevity #1.
And above all, Yes we literally dyno test every engine we build. even the ones that are sold w/o intakes. If it has heads and an oil pan, it gets a full comprehensive dyno test. Not just a run session, but actual dyno pulls measuring temp on all 8 cylinders, using UV dye in oil to check with tiny leaks, etc, etc.
Lastly, we're trusted by Jegs, Summit, Speedway, and more.
