This cam has a compression release that will clear larger stroked such as 58mm cranks but will need to be clearenced between the lobes in most cases.

Testing data (dyno sheet shown) is on a 72x58mm tall deck 236 with our ported stock assembly shredder head, 1.2 stamped shredder rockers and milled to 13cc with our narrow body 40 pound dual springs set to 30 pounds of seat pressure on gas. The dyno sheet is a real number, not some fluffed up sales numbers like some other retailers post. It is intended to show where this cam makes power.
