Aftermarket Performance 2F Cams

[LAMBCRUSHER]

I am hearing this pop up a few different places as a nice grind for a 2F - do you have the specs for this @LAMBCRUSHER ?

I'd need to dig them up, but I will offer this: I feel the ramp speed is too fast for these old boat motors. I would recommend someone who wants to use these specs might consider having them cut onto a new billet, using a slower ramp. Grinding existing profiles tends to make for fast ramps, which I feel leads to float. Some float can be counteracted by using more robust springs, but only to a point. Mine, for example with 1.6 exhaust and 1.92 intakes and SBC springs and hardware is loud as heckle, and I would not use this setup again, myself. I will see If I can find the specs.

@PabloCruise I am using the KC859/262 duration speced in the table posted above.

It's likely very critical to use oil with plentiful zddp additive with a aftermarket cam.
