ms3 / torquer v.2 / 233/239
I voted tv.2 because you said your going to be street driving but my question is why not the TV3 or MS4 as they are the newer supposed to be better versions of the same design?
I've seen people make similar numbers with smaller cams like a 228 when compared to big cams like the MS3, both a little over 400rwhp on a M6. for a driver I think the biggest cam I would go with is something like 230/235, pretty much like the torquer cams because they still make the power low enough and dont lose alot of torque.
Also consider the LSA the lower lsa's like a 110 will give you a real choppy idle and move the powerband down a little and a lsa like 114 or 115 will smooth out the idle but move the power up into the powerband.

I chose not to select the ms4 because I dont want ptv clearance issues. I just want a simple swap other than changing valve springs, oil pump, pushrods, intake, but not looking to fly cut my pistons for a dd.
Look at the old TSP 231/237 .598/.595 112LSA
Ran this on a 75RWHP shot.
All it had was supporting bolt ons, 3.73's, 3600stall, 85MAF, etc. Full weight street car. Ran low 7.4x's all motor and 6.9x's on a 75 shot. Made great power in the 6200-6400 range.
Other than that the 233/239 gets my vote if your not gonna go custom, and if you want GREAT streetability

I think you might have it backwards. I believe the lower lsa moves the power band higher in the rpm's and the higher lsa moves it lower in th rpm's. I also think the higher lsa will give you a higher cranking compression as well since the valves dont overlap as much. Usually when you build a high compression motor and want to run on pump gas you can run a lower lsa to help reduce detonation problems. Feel free to correct me as I could be wrong but I believe this is correct info.
Further more dont be so concerned about dyno numbers. HP and TQ on paper don't mean ****. I have a custom cam by Pat G and its not a huge cam by any means. Sure it only made 385hp and 360tq but im walking all over other H/C/I LS1 f-bodies with bigger cams making over 400hp at the tire. That piece of paper didn't help them and it won't help you either. It's all about power under the curve.
Mel had it right, the tighter, or lower the LSA the lower the powerband will be. For a street car you would want less overlap, as that is what causes ruff idle, surging and general pain in the ***-ness to drive. A 112-114 LSA is ideal for a street car BUT depending on your access to a good tuner, you could run a 110 LSA like me and DD the car

Verdad Gallardo Does changing to a lower lsa also help reach your max hp and torque at a lower rpm? Like if you got a cam thats rated from 1900 to 6500 with a 113 lsa and you change it to a 112 lsa would that move the cam to 1800 to 6400 or would it still be the same and just hit peak sooner.

Sounds like the cam to use would most likely be the torquer v.2 since it does have a broad powerband and usefull torque and most likely go with a 112 lsa but then I also think it would be cool to have it on the 114 just so people dont think anything is done to it but I love the sound of a hard hitting cam.

What cam do you have in yours and I would guess you like it since your friend is getting the same. Maybe I could get that v2 off of him to help fund his new cam.

He liked his V2 but hes building an L92 now so he's getting a custom grind from Pat G like I did. Mine is a 23x/23x .61x/.60x 110+4 LSA. Sorry for the "X"s but I don't know how Pat feels about his cam specs floating around the forum. If I were you I would PM him and have him spec you a cam for your car specifically; your goals, purpose, mods, future mods, and idle quality. It only cost $25 more for the custom cam then a regular shelf comp cam.
