I think I have 300 hp in my 750 dollar 318 lock, stock, and barrel. Anyone have a 100% stock 340 and wanna race??? equal gears, no headers. I'm game! I have less in my entire motor, including the 2 4bbls sitting on top than you'd have in just the block for a 340. And I think I'm in for the win ! Been beating the tar out of it for 6 yrs and counting.... :)
