So for $300 I just picked up a pretty clean 97 Mark VIII with 168k miles (a little higher than I wanted but the motor is mint and I couldn't resist the price). I'm planning to forge and supercharge the motor safe up to 1000 HP but I'm realistically wanting 500-600 HP on pump gas for the street. I just want to build it right the first time and know it's safe for pretty much as much power as I want.
I'm still a couple months out from removing the motor, but I wanted to get some insight. If you know of a build thread, parts list, gotcha's or uh ohs, or anything at all that might help me please post it below. Budget is still in the works, but I am guessing it's going to be around $3-4k on just the motor (forged bits, machining, heads, cams, etc) minus the supercharger.
Here's what I do know:
Forged internals (any suggestions?)
At least C heads but really wanting late 2003 or 2004 Cobra heads (fixed cylinder 7-8 cooling issue)
Probably Cobra cams
Roots or PD supercharger (intercooled)
