Camshaft help.....340 Dart Swinger

I have been following this thread because I have similar issues with my engine, so seems that the OP has abandoned this thread I am going to hijack it because there are people here who know what they are talking about. So here I go
68 340 .030 over
71 j heads 2.02-1.60
Stock 10.5 pistons
268 xe cam
18* initial timing 34* total
727 with 2200 stall
355 gears with p70 215 tires
The cam was installed dot to dot
Now I know that I have to degree the cam are there any tips any of you can give me?
I have a dial indicator and a degree wheel.



Check and verify the ICL first. If it is soft on the bottom, advance it 4 degrees. If you want to move the power curve up, retard it 4 degrees.
