Cam degreeing question

Regardless of what timing set you have, please do yourself a favor and degree it in...those marks on the crank gear may say 2* adv/ret or 0*, but if the cam is ground wrong, or the cam gear is dimpled on the wrong tooth, you could be as much as 16* off...been there done that.

Agreed. A few yrs. ago I degreed a cam in on a buddy's 454 Chevy and it was 18* off. After some diagnosing we found the timing set was marked wrong. I also rounded up 4 different brand timing sets and using the same block and cam degreed each. None were the same. Only 1 was close enough to use as-is. 2 of them were 4 degrees off. In your case I'd be tempted to degree it to 2* advanced but not more.

Correct me if I'm wrong but I believe the 273 commando's used a single plane intake and a solid lifter cam. That along with the small cubic inches will generally produce a fairly high rpm peak torque.
