I talked with the gentlemen that bought the camshaft about a hour ago. We discussed how the camshaft was setup & what kind of clearances I typically see.
What I have issue with mr. predator is you state you wouldn't run the ms4 on a 110 lobe seperation. If your so concerned about the p/v on that camshaft why don't you checkout a few of the other large camshafts available on the market. I think you'll find there is a 240/244 with tons of advance, and a 244/248 camshaft both of which have considerable less p/v than the ms4 does.
All I'm trying to get across here is 1 degree of lsa does not cause a camshaft to not clear.
Furthermore, the camshaft in question never was checked to have anything near .03x clearance. That was a rumor and nothing more.
I'm sorry I got so bent out of shape at you predator, but a lot of people rely on you to tell them accurate information. Claiming a camshaft will not clear based off 1 degree of lsa is just a little bit crazy...

EXACTLY! That's less than the recommended clearance. Point proven.
I was thinking some of the MS4 guys would speak up to save face and not let that measurement be the only one since it looks so bad, but they didn't. Left him hanging out to dry.

I put the MS4, PRC springs, pushrods, retainers and ported LS6 oil pump in all from Texas Speed on my otherwise stock motor, (to include heads) and I ride the hell out of her. I had it tuned and slammed on the rev limiter almost everyday I drive it. I think that if something was going to break, I would have definatly done it. Great setup!
You're serious? You guys are missing the point. That's like saying, "Only about 2% of smokers get cancer, so cigarettes aren't any big deal." Just 'cause you're okay doesn't mean everyone will be, or that YOU always will be. That's just ridiculous. Only on here would any group of supposed adults try to say that the safety recommendations of hundreds of experienced engine builders is worthless compared to what they or a company says.

LS1ruls...dont be a girl! Dont come on this site talking about "about being adults, and, only on this website". We are all just sharing our personal opinion about our setup. If you dont like it, dont log on to the site!
I did and I'll continue to. Get over yourself. And by "here" I meant only on the internet. You're no authority, and you telling me what to do means nothing if you're too pussified to drive here and do something about it. So step up or shut up. Get back to the cam talk.
How are so many overlooking the standard and commonly accepted safe clearances, and trying to argue as if it's right to do so?

Then don't tell me what to not say. It's Greenup, Kentucky. Drive up if ya gotta talk big. Man it gets old listening to all the geniuses on here. Dude, the point was just because you spent money on the setup doesn't mean you have to defend it having tighter that recommended clearance. Okay it works good. That said, it is still tighter than recommended.
you can call us MS4 guys stupid, idiotic, crazy, and ignorant for putting such a big *** cam in our cars. MS4 and no kind of valve relieves is almost asking for trouble especially when spinning high RPMs. But everyone on this site is a big boy and can make their own decisions. If i slap the valves on my car guess what its still my car, you live you learn. I does take alot of ***** to run this cam, its not for the weak hearted Just remember there is a thin line between pure genius and insanity, and the MS4 happens to fall right on that line.

To end all of this quit fighting on the forums like little girls and call texas speed and ask them! They are great guys and no there ****.

Just bc youve been lucky so far means nothing. If you wanna keep running that cam and not having the safe clearances, fine, your guys' motors
All he's trying to say..you cant say it "fits" when its not within the recommended clearances. you could say: "it works.."
