Cam Grind # question
Cam Grind # question On the cam card under the grind # it states HR114+2
I'm just wondering what does the +2 mean?
Thanks <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Cam Grind # question Ok, but since I'm cam-retarted. Can someone explain to me what does +2 degrees advance mean exactly? Is there anything special that needs to be done during the install?
Thanks again <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Cam Grind # question Unless you are planning to change the cam timing, just install it straight up, dot-to-dot.
If you have an adjustable timing chain, you can advance or retard the cam a few degrees. If so, I would degree the cam first. You will need a degree wheel for this.
Let me guess --- did you just buy this cam from Thunder Racing (224/224 114 +2)???

Re: Cam Grind # question Advancing the cam 2 degrees means that the intake valve will close 2 degrees earlier then with 0 degrees advance. This means slightly better low-midrange power 1000-5000 with a small power loss at the top end 5000+.
