Horsepower Estimate?

OK you got me 450 hp. lol
check out Jim/IQ52 thread " mild 8:2 360 on the dyno"

If Jim's thread doesn't support this 340 making more than 300hp if everything was in decent shape, not sure what would convince folks.

@PRH
Had a 360 with a 214/224 cam. Car ran high 11's at 3000# Sounded like grandmas 318 Duster.
