We will get some pics up tomorrow. WHat we found was really surprising. IO am not even sure how the car was driving at all.
The cams were off by a 1/4 TURN...probably 10 or more teeth...crazy. So if the timing notches in the gears are supposed to be at 12 o'clock(lining up with the V Cover notches)..they were actually at 3 and 9 o'clock. There were actually marks added to the gears to get it in some sort of time....wrong time.
The exhaust cam actually seems to cause the valves to hit the piston at TDC. I will get pics up and then give a more detailed idea of what the cause was. We are pulling the head to see what is actually going on. It is possible the head was cut too far and is too short....the valve job may be completely terrible....or the cams could be for a different application. There are other possibilities, but you get the idea. So I will follow up tomorrow with more info.
I feel bad for the customer, because if the head was cut too much, we have to replace it. At the very least, he is looking at a valve job...a couple new valves...decking...cleaning, etc. I am hoping the combustion chambers and pistons look good. Lets keep our fingers crossed.
Thanks guys.
