Trying to sort out some issues on my engine..
New FRPP crate engine M6007 C347. Alum Z heads w/FPA headers.
I am getting all kinds of spark arcing on the valve covers and the headers.
Obviously this is causing the car to miss etc..
Brand new red Ford Racing plug wires that came with the crate engine.
Checked the wires and boots no visible burns or cracks..
This combo is an EXTREMELY tight fit in the 65 fastback...
The boots on some of the plugs touch some of the header bolts in a couple of spots
The car is scheduled to go in for a complete tune including dyno time next week and I need to resolve this problem before it goes in.
As a side note the car also seems to be set up very rich (carbed).
I am getting an occasional backfire thru the carb.
While checking the car for spark arcing the headers started glowing after running the car at idle to about 2000 RPM's for about 10 minutes.. Hopefully the tune will resolve this concern.
Any suggestions?
Scott

wouldnt the glowing headers indicate a lean condition????

Try some different wires
