How tight do you set yours? I have never really got a straight answer to that question.. mine will shift if too loose but i dont want to over tighten and cause premature wear on anything.
Always adjust the belt HOT, not cold! By hot, I mean take the car for an extended drive and bring your 1/2 ratchet, 3 inch extension and 15/16" socket with you. Pull over, shut it off and do it then. You should have 1 1/2" deflection HOT, not cold. If the belt it too tight, it WILL wipe out the snout bearing & seal, then the front crank main bearing and next snap off the crank snout. My friend made it one block before he broke his new blower on his 340 because he adjusted the belt cold. The stock crank snout was never designed for a lifting load like the blower can put on them. That is why they make crank supports with an extra bearing for racing.
