What would it take to get a 05 M6 to around 450whp?
The car already has a Vararam intake, long tubes, catless X-pipe and corsa sport exhaust.
Don't want to go forced induction.
And yes I've heard about a 100 times..... sell it and by a LS3 price difference around here between a ls2 car and a ls3 is pretty huge(10k) lol
Ported 243 heads or aftermarket, a fairly rowdy cam, and supporting mods to handle it should do the trick. 450 isn't an unreasonable goal but dont get hung up on numbers. What do you do with the car? Are you drag racing, road racing, just cruising and want some more sauce? I would say unless you're racing the car stick with something a bit milder and don't get hung up on horsepower numbers.
I'd rather have a car that makes 420hp and has good street manners than a max effort build that makes 450hp and drives like ****. Just speaking from my own experience. I kept things on the milder side this time with my LS3 and I'm glad I did, the car has near stock drivability and still sounds and runs great. My Trans Am had a fairly rowdy cam in it and it was a pain in the *** to even move around a parking lot. I can tell you which of the two setups I got more joy out of and it wasn't the Trans Am.

Thanks that is helpful!
Really its a weekend driver, live out in rural ontario, so no traffic to contend with. I guess the occasional auto cross/track day(2 or 3 a year), and mostly need to keep ahead of my brother with a bolt on 23 Mustang GT LOL.

Yeah man for sure. Honestly (I'm not sure if they make it anymore) but a Texas Speed 228r would be a good Cam for what you want to do. Plenty of chop, good drivability, works well with the 243s. Just do yourself a favor and go to a Johnson short travel lifter. Its good insurance and you'll never have to worry about them again.

Just invite him to a backroad or roadcourse, **** even a dragstrip.
Corvettes make up in weight, what they may lack in power and a 10spd

I dunno those Coyotes with a few bolt ons and a 10 speed are nasty lol. I've ran a few now and It's usually whoever gets the hit. They really work at the drag strip if you throw a tire on them. Put em on a little bit of corn and its over.

With a FAST intake manifold and ported heads, it's fairly easily done without too nasty of a cam. Easier yet if you bump the static compression ratio up to the mid 11's. That's assuming you have decent access to premium fuels (93 octane or there abouts).

If you accept the fact that your most effective way to get there is a Cam you are going to need to work with a tuner anyway. The advantage of selecting one to work with before the mods start is you can baseline exactly what you have at the rear wheels now. In addition, you and your tuner can work out options for getting to your desired goal which in the long run will save you both time and money.
I think you already started "planning" by asking for thoughts and experience. For me, the next step is getting the data you need from the car you have so that you and a tuner can together design a solution and hits your mark the first time rather than throwing parts and labor at it later. Good luck and enjoy the process. It can be very rewarding when you know you've done your homework and it all comes together as planned.

This man speaks truth. I wouldn't recommend you getting an LS3 engine, but I would say for your N/A goals to get a set of stock LS3 heads, factory intake, and a small cam. The LS2 to LS3 horsepower delta is not primarily in the difference in displacement, but rather the janky LS2 intake and head flow. On my first LS2, I went with a ported FAST 102, ported TB, ported PRC cathedral heads. cam, etc. If I had I to do it over again, I would have gone with the stock LS3 top end and let the blower do the rest.
Lesson learned, never again. Push the air into the motor and call it a day. I know you said you didn't want to go F/I; but if I were you, I would leave your LS2 alone and get an ECS or AA centri kit and be done. You will smoke the stang and remain very reliable with perfect street manners. If you desire more later, then go with the LS3 top end with supporting mods. I was also anit-F/I when I started but it really is hard to beat for the cost to performance ratio.
