431 rwhp???????? Are you on the gas? If not, you are getting a little too greedy. 431 rwhp is very very good for a 347. They say generally you only average about 1-1.5 ponies for every extra cube, so in that case I would be very pleased. I have stage 2 Twisted Wedges that flow about 285-290 intake/220 exhaust. I hit like 380 at the tires. 431 is generally a very high number, blown, gassed, or stroked. I would be very happy.
