Hi, I'm looking for those couple extra tenths to take me down into the high 11's. After talking with several people, including Brian Earick, consensus is that I should first have my cam degreed to see how good/bad it is. I have a Poston 113A cam and installed it straight up when I built the motor. Is there anyone in the northeast Ohio area that could help me out here? I don't have a degree wheel or the knowhow of how to do it. Obviously I would be willing to drive to where you are to have this done. Thanks. Phil
wheels are cheap, you can get one from local parts house or summitracing.com http://buickperformance.com/camdegree.htm and some info from crane cams, info applies to your poston cam http://www.cranecams.com/instructions/degreeing/degree.htm its pretty straight forward good luck
Phil, I am in Stow, Really busy now but you are more than welcome to borrow my wheel. Call me if you need it. 330-256-0354
Club Degree Set The BPG has a cam degree kit - I just used it to confirm my cam. Are you a member? I have not sent it back to Jim W. yet - I can send it to you if you want. PM me if you're interested. I'll be able to package it and send it out Monday - I have a graduation party to throw tomorrow.
Yes, I'm member number 1102. Actually, Steve Gray was nice enough to let me borrow his degree wheel kit. I actually already took the front of the motor off (GGGRRRRRR!!) and will probably do it this afternoon. On that same note, I really hate Steve. As he's giving me the kit I notice a 455 sitting in the back of his truck. He procedes to tell me he got 2 complete 455's, extra set or two of heads, and a TH350 tranny for, get this, $100.!!!!!!!!!!!!!!!!!!!! I hate him. Why can't I fall into a deal like that??? Oh well, better get mine running right first. Phil
Phil, when you degree your cam make sure that after you install the cam gear bolts, turn the cam counter clockwise and hold it while tightening the bolts. I found that there is ~3 degrees variation possible with the play that exists in the clearance holes. For example the intake centerline (ILC) can vary from 108 to 105 (for a given keyway) depending on which way the cam is held while tightening the bolts! Holding the cam ccw will give you 108 ICL while holding the cam cw will result in 105 ICL. With my TA advance/retard gear Mike T at TA suggested that I rotate the top gear one tooth and make another dot on the gear to get the 107 ICL I was shooting for. While each tooth and keyway on this gear is labeled (8A, 6A, 4A, 2A 0, 2R, 4R, 6R, and 8R) they are not all correct! There was a big difference between 6A and 8A and I spent quite some time "trial and error" to get the ICL I wanted. I finally found a combination that gave me 106.8 ICL with my TA413 cam.
