If it's a 0.25 or .5 max you may have a chance. I don't think it will last long on a track slag myself.Before anyone says it yes we all know a handful of owner who have 450 or 500bhp on a 205 block, few have been lucky, most haven't.
I spoke to a few tuners about this last summer,most say go to the 200 block.
I would decide who's gonna map it and what ecu your gonna be using, then get your tuners advise first before you plow your money either way.
I hope this helps a little Rich.
