Default LQ4/L92 with Vic Jr/carb cam

Was toying around with different cam designs again and came up with a 224/232 109+1...

10 degrees of overlap so it should have a nice hard hittin exhaust note. This should make it peak around 6000ish (40* IVC)and carry til shift point at 6300 and still have good midrange torque since the EVO is 46*. IVO and IVC are pretty close at 4* and 6*. Keep in mind this will be in a 4klb street car. Am going to talk to EPS and see if they think I'm on the right track here. Opinions?

Yea, EPS will probably like a grind like that for the rectangle port heads. I think it would work well, i like my RPM range up to 7000 though since these engines dont mind spinning up that high.

what is your goal?
what is your scr?
heads milled?
dont really know what to opine since not much info is given about your build.
usually l92 head engines favor longer duration exhaust side biased cams

SCR is up in the air at the moment. Another member on there said he's been running L92's for several years now milled .070 with no problems and others have said not to mill past .030, so my SCR would have been around 65/66cc chambers which would be somewhere in the neighborhood of 9.6 with the MLS gasket, but I may mill further if others have been running with no problem. I'd like to get it around 10 if possible. I know that with that much milling, though, I'd have to flycut.
