Looking for a little more power out of a 318

I've got a 318 in my Barracuda. I used a Comp Cams he 260 and the Eddy performer (port matched) . A 3 angle job on the heads and 340 exhaust manifolds. I figure it's about 275-280 hp. To get to 350-375 you'll need alot more cam and more then my 9-1 comp. Why not build a mild 360, that would be a piece of cake and alot more streetable! The problem with the 318 is any major changes kill the torque. It's a great motor but you'll have to run a tall set of gears and forget about gas mileage...but it will fly!
