The base 290hp crate engine costs $2003 now. That's "dealer net".
Everything except flywheel/pulleys/exhaust mans.
Most dealers sell at 10%-20% over do to competition.
Not a bad deal.
GM also offers "power packages" for same engine up to 360hp, but price go's way up of course.

Some GM dealers buy mixed truck loads at a time and get extra 5%-15% discount, then sell to other GM dealers who don't what and/or cant stock'm do to space. Usually at cost with no shipping.

Or opt for the 350 HO/330hp. Also complete less flywheel/pulleys/exh mans.
Dealer net on it is only $4731 LOL!
