A little background information:
Currently
A 1969 Ford 302 block bored out .030
Comp cams XE268 cam
AFR 185 heads (1420 I believe)
Cast pistons 9:1 compression...no work has been done to them.
I have wiped out two cams before it was discovered the oil slinger needed to be taken out. The heads had been 68 4V heads, but a chunk went missing under the spring seat on one cylinder.
With the new cam in place and the 185 heads put on, it is idling fine. Unfortunately, when the rpm gets up to about 1500 rpm, one cylinder begins to make noise. This same cylinder has caused issues before, and is one cylinder that kept wiping the cam lobes.
The engine has been pulled out and checked by a machine shop with no problems with the block. The garage that has the car has pulled the engine apart twice and cannot find out what the problem may be. I'm looking for any ideas as to what may be causing the noise.
