I HAVE A 69 340 THAT THE FIRST THINGS PUNCHED ON THE FRONT NEAR THE HEAD IS FW, and i am wondering what numbers should be on the front? and how many numbers/letter should be in a row? thanks
I don't know exactly how to explain it, but a water test is some sort of high pressure test performed on the engine block. I do know it was done on all Hemi motors, most Max Wedge, and various other HP blocks during the muscle era. I have a call in to my Water Test guru for an accurate explanation, I'll post his answer here. Geof
I had to grab a book for this one. F is 1970, W is Windsor Ontario, then there should be 340, then a P, then a number between 2895 and 3259 (date code), then a daily production code 0001 0002 0003 etc. HTH
