help!!! ticking noise from 427
I recently installed a 427 in a friends 66 vette. completely new motor. it runs great exept for a ticking noise i cant figure out. at first i thought it had to be valve adjustment. not so. with a stethescope the noise is loudest on #8 cyl right at the exhaust port. tried adjusting valves about 5 times. no change. changed lifters(hydraulic) still no change. inspected all rockers & pushrods.(stamped) all look good. removed head & replaced loose valve guides, still no change. I'm running out of ideas. any suggestions?
thanks, Jason.If its not blown, it sucks.
