All right now you got me wondering how do I know if I put my cam in the wrong way I bought this cam 20 years ago. I have no idea what the specs paperwork got lost in the shuffle I know it’s a Lunati voodoo camshaft I do believe it’s a 262 in 268Ex part number LN 69702 lined up Dot to Dot it’s possible I did something wrong. did I had to advance the cam? can I just do a compression test to find that out
