Where's the weak spot going to be.Dyno results

[Oldschoolpony]

Well, I just got the dyno results, and to tell the truth, Im not happy. My combo, see if you could spot a bad spot. I have my suspicions.. 347 C.I. Scat steel crank, Crower Forged rods, Nowak 400 forged pistons( can handle 175 to 200 hp nos), sealed power plasma moly rings, probe 7 qt pan and stud girdle, all balanced. Motorsports double roller chain. Comp cams 31-762-9( around 600 lift and 255 durration @ 50 ). Comp solid rollers, comp pushrods, comp valve springs, Crane roller rockers. Dart Jr' heads(stage 3 )and cut (milled)50 thousands. Match Ported Victor Jr. Intake. B&G 750 carb. DBL pump. K&N filter, dont have the new style filter top yet, MSD pro billet distributor, MSD 6al Rev limit @ 7000 and blaster ss coil. Hooker super comps equal lenght long tubes with 1 3/4 primaries and 3.5 collectors 2.5" dual exhaust with a very close H pipe. Flow masters, motor sports aluminum drive shaft, 8.8 rear, moser axles, and girdle. And a WC T-5 with some extra stuff inside from rebuild. My problem is, We only got 431 RWHP and at 6700 rpm. I was kind of hoping for more. there's alot of money in this motor. Any ideas????
