First you complained about electrical as computers and sensors were so HARD for you. Then I explained you and use scan tools to find code as simple. Which it was not hard to do it.
Second, you thought I don't know about porting, valve sizes, canning, crank, etc. CLEAR you don't know me very well.
Hint, I own micrometer measurement, 3/8, 1/2 torque wrench, fuel pressure gauge, compression tester for gasoline,feeler gauge, spark plug test, Fluke 88, etc. Tell me what they use for?
I was overhaul on motors (DOHC, SOHC, OHV) for gasoline, OHV for diesel motor, auto transmission (I HATE IT), manual transmission 5-6 speeds and 15 speeds heavy duty (EATON).
