Hey Ed long time! I actually have been checking out the local salvage yards and haven't had any luck. If I do find a compatible motor, the yards usually don't want to sell me the tab, they want to keep it with motor. Thats why I was just going to try and wing it. At least I'll know I'm in the ballpark of in time. I also looked on ebay for some after market ones and the only engine in the world seems to be a 350.... I swear there is soo much more stuff for that damn engine! Oh well, I think I will be able to mark TDC, but I really just need to know about how fare over from TDC I need to go, it should be 6* advanced correct? If I can't get a picture an estimate on length from TDC will do. Thanks guys!
