My '65 block was rebuilt as a 331 stroker using a scat crankshaft part number 4-302-3250-5400. My builder reused the original damper and the original timing cover which has the pointer on the driver side. Now that I have the motor back in the car and running, when I tried to adjust the timing to about 12 degrees advanced, the motor just dies as I get near 12 degrees. It seems to run well at 30 degrees. Now I know that it is probably not really 30 degrees base advanced. I think that the timing marks on the damper are not in the right place to work with the crankshaft and the timing cover. Can anyone validate this for me and tell me how I would need to go about adjusting the timing now. My guess is that I need to find TDC using a piston stop and then when I find it, make a mark on the damper at the timing pointer. Then I would need to using a timing tape to adjust the timing. Basically, I looking for anyone that can validate this and give me some advice on what I need to do. Thanks
