need Advise from the pros

Hey guys i'm going to be doing a 383, I have a 1950 chevy bel air with 1967 camaro sub frame with a 327,th250 trans 8.8 rear end with 2.73 gears, long story short its a small journal so I went and bought a 350. Here's the plans get the machine work done on the block bore/oil pan rail cleanced/rods cleanced and balanced. And install the following parts scat 9000 series crank 3.75 stroke and 5.7 rods, clevite bearings, .110 dished speed pro hypereutetic pistons, rpm performer cam 234/244 @ .050 -.488/.510 lift its says power from 1500-6500 rpms. Dart iron eagle 200cc runners 64cc chambers 2.02/1.60 valves 1.437 dual springs striaght plugs. Crane energized roller rockers 1.5 ratio. Comp cams guide plates,and hi tech push rods. cloyes roller timing set. Professional products powerforce damper. Rpm air gap intake, 600 cfm edelbrock carb off the 327. I planning on a 700r4 and 4.11s. So what do the pros think will this be a good combo, if you see anything wrong PLEASE just say so your opinions count!! Also what do you think the compression ratio would be and about what kind of hp. and torque numbers thanks guys i read on here all the time but this will be my first post. kyler

my opinion

I'd use a flat top piston with a 70cc head.
and that 250 tranny is going to blow up in your face

6 in. rods for sure,& alittle less head runner like 180 cc,you need velocity.Explore the use of 1.6 roller rockers,they might be to much for that much lift thought,bee hive springs for sure.I think dual springs are sort of old school,dont throw in a stock 700r4,make sure it can handle your H/P this is the way I would go,IMO.
