It doesn't have to make 300 at the flywheel, I thought that would be a easy goal. If the car I find has a 318 already in it then that's good enough for me
He's talkin outta the hole in his back side. 300-325 for a 318 at the flywheel is peanuts. Especially if you're willing to use the Speedmasters.....you can do it with stock heads too, they'll just need some work. Like porting, larger valves and things like that.
