Is this engine builder nuts?

Ok so a new option just opened up for me...found an engine builder a few hours away that will sell me a LA 318 9:1 long block with ported heads and bigger valves, ground crank, tanked block, mild lope cam, etc. he claims 310-340 hp and 300lb of torque, for $2999. I bring him my core 318. I figure another $1000 for an intake, carb, distributor, etc. then obviously I do the install myself, which doesn't scare me. I know you guys prefer the 360, but I can't find an off the shelf long block 360 at that price. I'll keep looking at 360s but this is an interesting option
