I have a stock engine m6 with 57k now.
The plan so far is afr 215 heads milled .020 upgraded springs(.650 lift, for valve float insurance) with a 4.160 bore gasket at .040 thickness(ptv issue?), a fast 102mm intake and throttle body with 36lb injectors and fast fuel rails. Kooks headers and off road true duel exhaust. Car will be street driven only(for now) because its a convertible without a cage. My idea of a camshaft so far is 228/228 .588 lift 114lsa. As soon as I get a good experienced green light on the build I am ready to purchase and build.
Any flaws here? Looking for feed back...

 

Looks like a great build, but if it were me i'd go a little more aggressive on the cam. I mean you have awesome heads and a awesome intake, so why limit it with a smaller cam. That's just me though...

 

That would be a really nice driver. I had a set of TFS 215's in my own Z06 and had a mid 230's duration cam that made 500 rwhp but I later pulled it for a mid 220's duration cam. The car lost 15 rwhp but was incredibly more fun to drive. It was the closest a 5.7L felt to a LS7 I have ever come in down low mid range power/torque.

Contrary to how most think the better heads/intake typically the smaller the cam you should run especially considering most LSX guys do not change intake runner length.

 

Thanks for the replies. I'm talking with Mamo about his using his services now and he says the same thing about the less aggressive cams. It should be quicker at street speeds. I don't want to leave any power on the table but it makes sense to me.

 

If your interested we will be glad to spec a cam for the application. See a sample of what you'll get http://pcmofnc.com/images/samplecamcard.jpg
