Thread: Noisey lifter at startup???

Tweet

I've recently posted about this, the 331 stroker motor I put together is noisy as h*** until it warms up. I also have a roller cam and Harlan Sharp roller rockers on Edelbrock aluminum heads. I think some of the noise is coming from the piston clearance and stroke, but it is hard to be sure in an engine where certain noises come from.........they telegraph so much. Roller rockers are noisy too, I hear. I've torn mine down twice to find something out of spec and can't find anything.

Everyone I have talked to says don't worry about it, so I'm not. I'll just crack the caps on the headers open a little so I can't hear it. Like yours, mine seems to run fine otherwise and revs like mad, so unless something happens like oil pressure drop I am not going to sweat it. Maybe this is the price we pay for building a high performance engine? Maybe aluminum heads are not good at masking sounds like cast iron ones?
