Hey everybody. I just did a rebuild on my 350. 30 over, flat top pistons, new crank/rods/bearings/flexplate etc. Anyway.. compression is now .75 higher than before (10.25:1) and the motor is definitely harder to turn over with the fresh hone and rings. I got the engine in the car and got ready to fire it up today, and decided I'd check the starter after I primed it to listen for odd noises... sure enough I found an odd noise. The starter engages the flexplate and it cranks over fine.. slightly slower than before, but, it still turns over. I noticed a sort of noise, best described as maybe a clunk or maybe a click. It's not crazy loud or hard, but you can hear it over the starter. At first I thought it was an issue with the flexplate/torque converter so I pulled the bolts and made sure the torque converter was seated in the front pump, then pulled it out a bit and shimmed it up and torqued it down. Then I thought maybe it was a rod knock. Pulled the pan, checked torques and clearances again then cranked it over... noise went away. There's no signs or evidence of contact on the oil pan, and the new crank and rods are stock dimensions. I'm pretty lost here. Any ideas?? Yes I did check PTV clearance and set cold lash. Any help would be greatly appreciated. I'm lost on this.
