Default 408 stroker motor build help

Hey guys picked up a lq9 block complete with 317 heads. Im wanting 500-600hp N/A 408 stroker motor. Its going to be a D/D and maybe see the track once or twice every year. What is needed to reach this area of power?

I have a newb question cause I haven't done the math yet. What is the stroke in inches to take a 6.0 to a 408ci? Also, where does that put your max redline if you have all forged parts? I know if varies from rod to rod and weight of pistons and stuff... but roughly?

408ci = 4.00" stroke and 4.030" bore.



I'm currently building a 408 for a daily driver. It sounds exactly like what you want.
