If it's a 367(?) it's not a stock small block, that's probably why you cannot find any info on the internet. A 350 (5.7 liter) bored out could yield approx. 366 cubic inches maximum, and unless you know what specifically has been done to the motor, there's know way to give you a hp rating. You would have to dyno the motor. If it's a stock 305, (5.0 liter) 150hp.
