Not really impressed with any of the regrinders out there . . . never bought a cam from Rocket but I've bought two Delta cams and degreed a Bisi cam for a guy.Ive talked to him in person about it before, just use the OEM cam gear and set it up to zero. Thats what he wants you to do.
My issue came up when I got a cam that I didnt know if it was ground on a D15 base or a D16 base cam. He couldnt tell me.
What does any of that have to do with Colt cams?Not really impressed with any of the regrinders out there . . . never bought a cam from Rocket but I've bought two Delta cams and degreed a Bisi cam for a guy.
I really don't think anyone has actually measured the ramps on a cam doctor and are taking into account the radius of the follower.
Valve timing events are off in everything I've ever checked. Put it on ICL and IVO/IVC/EVO/EVC are close but not exact.
That all of the regrinders and most of the manufacturers I know don't really care enough about the import market to take it seriously.What does any of that have to do with Colt cams?
I don't need to deal with them to read the original post.You just made all of that up. You clearly dont know Colt cams. Good job. When is the last time you dealt with Geoff or Colt cams personally?
LOL.In fact I would bet you have never ordered, or installed a cam, in an "american v8"
Because read the original post. My god, it isn't that hard to connect these dots.I mean you said it yourself, you have never even seen a Rocket cam or colt cam, only a few Delta cams and a Bisi cam. Well, I already know from experience owning both a Bisi cam and a Delta cam its not something I would recommend. But that has nothing to do with Colt cams. Why you would post about those products in a Colt cam question thread is confusing.
The block(d16y3) is decked 0.13mm, the head casting (d15z6 = y8 ) is milled 1.33mm. Adj. cam gear is a must, to set even the stock cam. We all know how exact are the marks on the oem plastics. Even the TDC mark on my crank pulley is 2.8mm off(new oem key, preloaded prior tightening) - compared to the piston stop/degree wheel method. Imho, they might be close enough for stock engines, but not for 10.7:1 CR, turbo and an aftermarket cam.unless you shaved the head and or block , he usually says run it at 0 degrees as it performs best.
