Craigslist dude on crack!

Just posted in tech because I wasn't entirely sure if there was any validity to the guy's claim that his combo could churn out 400 horses and/or involve heads that cost $6k. I mean, heck, a set of brand-new GT-40 heads go for, what, $1000 a pair on eBay...?
 
That guy is on drugs. No way those heads cost $6000, even if he got an NHRA Top Fuel crew chief to port them himself. Summit has TFS High Ports for $1287.95, and the new ones are an improvement on the original design. I'd say those are maybe $2500 heads, so I'd subtract $3500 from his asking price and make him that offer.
