Engine nock at low rpm
#21
got a factory lift pump? after i pulled fuel plate in mine it took about 1 month of lead foot to starve lift pump enough to tick loudly at idle to about 1200 rpms then i could not hear it. its mid engine mounted to block so everything carries the sound. loud under hood loud in fender well loud from the front. i put a raptor on with self built filter setup. if you havent already put an airdog on it and get a tork technology ofv truck runs smoother and fuel system will now be supported well enough to run 370s and pump with divertor valves. if it doesnt cure the noise at least the fuel setup will handle a built motor. in my experience melted pistons dont get quieter, bc they just slap harder and faster.

yes. i have factory lift pump. but the noise is not a ticking. its almost a rattling noise and its unbarably loud. mid engine halfway back. and i have no loss of power. wouldnt that make u loose power? also. i have no fuel shut off selinoid so i can hold lever down. when i hold fuel shut off lever down and crank my motor it sounds like a 3 nocks real fast until motor turns full rotation back to that point then does it again.
