Eh, I'd go the way of an LS6 crate engine from Chevy. They're only $5030 plus shipping for a brand new engine. (With the Corvette Z06 driveline, it's worth 405HP.) Who knows if the thing would fit, and how much custom fabrication you'd have to do, but since we're dreaming, I thought I'd offer the "low cost" dream alternative. :-)
