[DeTomaso] Harmonic Balancer

[JDeRyke at aol.com]

I hate to complicate things like this, but there are three different timing 
pointers and two (at least) front covers for various years of 351-Cs. I 
don't expect any of the combinations to show very close to true TDC. If the 
heads are off the block, it's pretty easy to find TRUE TDC and bend the pointer 
to permanently indicate TDC on your Romac- which is a far healthier 
assembly than any 42-year-old balancer. 
But if the mismatch is only a few degrees, remember once the hard parts are 
bolted in place (cam, crank and harmonic balancer), the timing mark is 
mostly for our convenience. The engine really doesn't care what number is 
showing on the timing mark as long as spark arrives at the correct time. Good 
luck- J Deryke
