Interesting read! I have one of bobo's cams with 20hrs on it and 5 bad lobes, or was it 4.. The only reason I only have one cam of his, is because I sent the next one, that I did not order, back to him. He has hated me ever since for making him eat $350. That was in 2008. The block I ruined with that cam sits in the corner waiting for a rebuild. Too much metal in the skirts and scars on the walls to just reassemble. My loss was a motor worth 100 times more than his loss!
Some day I would like to put a big crank in it and slide it under a old Chevy cab over.. Maybe.. Hopefully others will not drink the bobo Kool aid and learn from other people's stories. Dick |

I could probably do better than that with a set of GM heads and leave 2 spark plug wires off.

So far we have learned
Some of these cores quality suck? Some of these cams are beating parts up? Most of these "custom" cams, aren't very custom at all. I mean, a 9:1 540 with GM iron heads, gets the same cam pretty much as a 540 with AFR 325s and 10:1 , or a 555ci , or within a few degrees of a 502ci combo The timing sets provided, don't fit well without modifications Some cams didn't have the proper firing order as ordered, or as cam card stated Some cams have been removed, replaced with an off the shelf cam, and made more power , with less lift , and no longer having issues Some have had quality control issues with his AFR heads |
Wow what were them build specs?

Is there anyone out there that bought a set of MK cams and ended up with stout running motors that made good power??
|
Maybe this will abruptly end the thread. Lol. Power and hours of use is more like it.

Anyone have any issues with the Scorpion rocker arms?

MIKE TKACH (Quote) Been there w a camaro. You can do a 6-700 lift solid lifter cam and run 6500 in a basically stock motor. But hydraulic floats around 4500. I know you know this |
