OK. I've been searching forever and nothing answers my questions. My question is "I have a 248/248 can swap and I've read that optimal timing is 3.5 teeth or 5 degrees advance and we can use the jwt gears or re-drill the stock gears. I'm not confident so I bought one. No, I followed the instructions on jwt sheets, and 5 degrees is use #3 or 4 teeth back and the pin on the cams goes to the same number on the inner side. I did that, and I noticed that the cam lobes hasn't moved. It's still facing up like how u would align the intake cam mark. It's like using the stock gears on the proper timing marks with out rotating it. How do I do the 3.5 teeth/5degrees advance? "
