Comp cams xe268h for 318

  1. How's about get those heads off this weekend, look at what you have for pistons (no eyebrows or ??), and VERY precisely get a piston to TDC and measure how for down in the hole they are?
  2. Carefully cc the 302 chambers so that is know, unless you already have).
  3. Decide if you will mill the heads and how much.
Then the picture of what SCR you really have will be known, and then the cam situation can be better looked at. If you really have flat tops, down .075" in the hole, and mill the heads to 60 cc's or a tad less and use .028" head gaskets, then even the 262 is looking pretty decent: DCR around 7.5. (Less a few 10th's due to your elevation.)
Working on it I will try to get it done in the next day or two. How do you get the dcr number ? What info do you use?
