2600 stall and 3.55 gears 8:1 compression
200-256 @.006 with as much at .200 as you can get around .460 or better lift at those durations
the short seat to seat crutches the lack of compresssion and the .200 gives you the power tgat the gtround ib Detroit "repackages"white box" cams can't match eventhough you have had lots of comments from personal experiences
most of the low end cams from all the grinders are that way
.050 is worthless for picking a cam
you can do better with a solid post back if interested
stock springs do not handel more than stock lift well
Use the lunati 700 and 701 as standards for comparisons
