Well in my case,
$26k, it was new
$10-12k
$0
$0
If I was to do it all over again today, with the only objective to be fast and just look decent, I'd buy a Z28 for $5-6k, and blow $10k on suspension and drivetrain.
If you bought a V6 Camaro for $3-4k to get a decent one (unless you get really lucky and find one blown up), nothing from a V6 car bolts up, nothing. Not the tranny, not the k-member, nothing, so now you spend an extra $1k swapping stuff. Just doesn't seem like it worth the trouble.
Obviously I'm talking about 98+ LS1 f-bodys, LT1s are cheaper but I wouldn't want to build one of those. I wouldn't want to build a Ford Mod motor either, which is why a foxbody is so appealing. They are becoming so much cheaper to build, because most of the parts go dirt cheap. That turbo kit Dyno Brian was talking about really makes me want to go find a decent fox.
