[DeTomaso] Harmonic Balancer

[sean mundy]

I put a degree wheel on and made a piston stop and went about TDC discovery.  
Rotating the engine around and checking several times I found that TDC is where 
I thought it was and the stock pointer and stock balancer were correctly showing 0.  
It seems obvious now that the timing marks on the Romac balancer are wrong for my application.  
I've asked my engine builder and he reminded me that the Romac balancer is for a Windsor crankshaft
as that is what is installed in my stroker motor.  He said their was a snout spacer installed on the crank to make it fit 
the Cleveland block.  So I think if I want to use the Romac balancer designed for a Windsor motor and use my
stock Cleveland timing pointer, I will need to buy some timing tape and modify the balancers timing marks.  
Can someone give me a sanity check?  thanks!!!!
