mystery cams
The cam numbers are 901 105 103 & 104 02. The Carquip site lists the 901 105 103 00 as 1966 906 cams. What do the last two digits signify?
I'm disassembling a 2.8 twin plug motor that came in a race car I bought a few years back. Looks like the head studs stretched, 60% leak down on #1. The case has been time certed and they look fine. I torqued the heads (26 lbs) late last year, now they are all loose, about 20 lbs. Leak down earlier this year was at 5-6%.
