Im a little surprised here. There is a lot of information being tossed around here,but no one has asked the question, " who SPECD the cam". Typically,in a Procharger application,someone with pressure or boosted knowledge is involved in the cam selection process. Just like in turbo,charged anf nitrous set up,you start seeing some wider LSAs for a reason.Just because the cam card says Xxx degrees ground in, it doesnt mean it MUST be installed there. I would ask the person who actually specd the cam and or Procharger first if it was my momey ![](/ubbthreads/images/graemlins/Twocents.gif)

Steve Morris spec'ed the cam and bullet ground it. I just ordered a new dial indicator with mag base as my old one was questionable.

that's what I did. Steve Morris was my starting point also. Ended up with a comp cams grind. I always use the positive stop method to find true TDC. Most accurate way. I also run my dial indicator directly off the lifter ( home made with 2 lifters and a section of pipe in between ). To eliminate any confusion, I always degree using the opening / closing #'s ( @.050) on the cam card. I don't do all the lobes, but I dodo one intake and one exhaust. Never had a cam where one # lined up while others didn't. Possible though, as I never checked them all. ![](/ubbthreads/images/graemlins/beer.gif)

ok, finished degreeing cam today. I check open/close numbers. card says 23 open and 65 close. @.050 open I get 22 and @.050 before max lift I get 65. am I doing this right? the install centerline is correct at 111*. thanks
With a 268* duration cam, a .050 23 open BTDC and a close ABDC of 65* will be at a 111* ICL Your at 22/65 close enough. Im always off by a half degree or so. Tolerances when measuring ICL, is tough to get it closer then that. And its not needed, to be more accurate then that.

I thought the @50 open/close numbers where measured at .050 open and .050 just before close, but at the 50 before close I got 115. didn't match card, so I tried 50 after max lift and no match either. 50 before max lift and I get 65. why do they give the close point at .050 before max lift? i'm done with it now. I told him to check valve clearance and button it up. thanks
They don't provide any information on .050 before or after max lift on any cam card I ever seen Most of the checking numbers on the cam card are in reference to before top dead center BTDC and after bottom dead center ABDC on the intake and before bottom dead center BBDC and after top dead center, ATDC, on the exhaust Finding the max lobe lift on the exhaust and intake lobes in relation to BTDC and ATDC is the hard part without coaching, mentoring, or further instructions ![](/ubbthreads/images/graemlins/shruggy.gif)
