golen engine service does a great job.

they have a 383 stroker with 12lbs of boost that makes 600rwhp.

Well brainstorm this anything over 450 rwhp is gonna have traction issues I have seen a true 420 rwhp car walk the dog **** out of my buddies turbo Nova that makes 750 rwhp . Now at the track its a whole different story so my next question is this a street car or you only gonna run it at the track? To get 600 rwhp to hook up is gonna cost you even more money then you think. Whatever you plan on spending on this build multiply it by 1.5 and thats what your gonna spend trust me I am living through it right now.

well i was planning on using maybe mt streets for daily use, maybe 555rs just cause they last longer. and probably have some pro stars with some slicks for the track.

If you have a decent setup a set of DRs will be fine. I ran the MTs last year and am getting 555s this year again. You are gonna need a 9" and full suspension adjustability to get it down though. I can hook my 600+whp car in 2nd every time, and it will hook if i ease into it in 1st. This year with around 750whp its gonna be a little more interesting though.
And yes i drive this thing almost every day in the summer

A friend of mine just put down 589rwhp with a forged 353ci, LE ported heads, and 11psi of boost from a 67mm BB turbo on E85.

If your a nitrous guy at all, stock cubes(stock crank), eagle h beams, wiseco pistons, le3 top end and 150-175 jets should get you ~600rwhp with all the bolt ons. I did 520rwhp on a 150 shot through my th400 and big stall, daily drove it, and drove it every where. 600rwhp n/a and juice will most likely outrun 600rwhp on a blower also.

What kind of et/mph goals do you have or you just looking for pure power? Everytime I see someone looking for pure power it makes me laugh because I know they will be getting beat by cars with a lot less power.

Another option is a turbo setup, running 11.5lbs with stock heads/cam put me at 10.80 at 127.8mph, a real budget setup but plenty fast for most cars on the street. It wasn't even close to as fast as my h/c nitrous setup though.

well the car does see some track use but only every few months. i wanted it to be as comfortable to drive as i can get it. i really dont have a goal as far as track times because im not sure what a realistic goal would be for a daily driven, full weight car. i wont be gutting anything, the a/c will still work. the back seats will stay in the car. (except when i go to the track). iv heard bad things about turbos on m6s. someone told me they wont even hit full boost until 3rd gear

You could do a setup like mine. Puts out 600 rwhp and is totally streetable. I can sit in 110 degree weather with the AC on without any issues. If you're not planning on doing your suspension, traction is going to be an issue.
