360 Redline
I'd probably spin it about 6800 if its balanced right and the valvetrain is tight.
If you need any help turbo-mapping or a second opinion. Give a holler :D
I have a roller/magnum 360 in storage that will probably get stroked and turbocharged...it'll take some time for cash flow to speed up enough, but I plan it to be rediculous and very streetable :D
