All in all though, going by the dyno plot, and the tranny gearing, you can choose your optimal shift points assuming that your tranny is working the way it's supposed to.

Sure wish I had that A3/355 combo back...went 11.96 on motor with the HOT cam and there was more in it....oh well....starting over is fun too!!

Re: Please read this before you choose a cam!
trying to keep this thread alive to get more opinions/facts. Doing some research on what cam I want to install at some point in my 94 M6 . I generally look at the lift numbers more than duration.

As for specs.... give Cam Motion a call. They will be more than happy to work with you on a custom grind that fits your needs.

Re: Please read this before you choose a cam!
Thanks for the info mindgame, Im far from doing anything to my z. Just trying to do some homework. Was leaning towards a 224/230, or 230/236 but that maybe a bit on the big side. I considered the 230/236 b/c I see some people say its not bad with a M6. anyhow, I have a few other projects to finish before I can start buying things, so I have plenty of time to figure something out.

If you do a 847, 306, 233/239 or even 230/236 and shift at 61-6200ish, you will be in the low 13s! You'll be lucky for a high 12.
There are plenty of cams out there which can take advantage of your targeted range much better and will yield better times than a bigger cam in the same range. Please consider this.
Yes, I've had at least 2 people with a 306 requesting a 6200 rev limiter and a number of other people who shift at 6100-6200ish and that's on the stock tach, which is about 5900 real RPM.

Re: Please read this before you choose a cam!
Very good thread on cams!
I was wondering if anyone had opinions on the GM 846 camshaft for a daily driver mods in sig. Its a Crane Grind 222/230 .509/.528 with 1.5 rockers. The ones I have seen are ground on a 112 LSA. How high to these rev and what kind of power or times are folks seeing?
How would it compare to the Hotcam? The valvetrain I have now would support just dropping in the $175 Hotcam, but something tells me I might want a little more.
Keeping this thread alive!

Re: Please read this before you choose a cam!
306 stock heads m6 4.10 guy here. I am happy with the cam. No issues with daily driving. So far I have been shifting at 6500, but it still feels like a beast, even if I hit the rev limiter.... so I was thinking of going to 6700-6800. That still got me 109mph trap with some minor issues. I expect a 110 trap with good weather, and maybe a bit higher shift. One problem thoug is shifting at 6500 had me crossing the trap at a relatively low rpm, even with 4.10s.

Re: Please read this before you choose a cam!
I was looking at the Crane Cams 222/230 .509 / .529 112 LSA
would it be ok for a 6200 rpm redline? I just don't want to rev my stocker shortblock very high.... if i can get away with 6000 rpm redline i'll do it....
the cam seems to have more lift than the cc305 on the exhaust side but im not sure...
opinions? would use it with crane 1.6 rockers and comp 941 valve springs

Ion... kinda bringing this one back up from the dead, but do you think the 224/230 is a good choice even if you plan to shift at 6200? (stock heads). im not necessarily concerned about squeezing the best time out of my car, but id like the power there.

I really don't think that cam would make power at 6400 anyways..
