Heres the problem....I used to have a supercharged(12lbs boost) with b-303 cam, cobra upper and lower, 75mm bbk throttle body, 24lbs inj, bbk long tubes, stock ignition, gt-40p heads.

Now i have a ford 302 roller cam block, 10.5:1 compression, forged I-Beam rods with ARP rod bolts,Ford cast crankshaft,GT40P heads with Manley valves, X-303 camshaft, double roller timing chain, Ford roller lifters, hypereutectic pistons, high volume oil pump, graphite head gaskets, rockers.1.6 roller rockers, Autolite 2545 sparkplugs, Edelbrock Performer RPM intake, MSD Pro billet distributor, MSD 6AL Ignition box, Electric fan, EFI fuel pum with aeromotive(3204) fuel pressure regulator(set 7.5psi), BBK long tubes, Edelbrock 650cfm carb used, Blaster 2 coil. And im running 93 octane.

This new setup i have isnt as impressive as the supercharged motor i had.
I was thinkin of a different intake and carb setup or nos or maybe it just needs tuned....I dont know!
I still have the supercharger with both a 10lb pulley and a 12lb pulley-i just dont think its safe for the 10.5:1 compression and i have no idea how to hook it up with a carburated setup

CAN ANYONE GIVE ME SOME ADVICE??????

Think about what you just said,you just awnsered your own question....lets see that is what you expect when you go from a forced induction motor to a n/a motor...

I dont think Centi chargers run on carbed engines... and you shoulda done the 347 with that setup then you would be comparing apples to apples. Better yet the 347 with that charger and EFI then you would be rockin. YOu went from like mid to high 300 RWHP to like maybe 250-280

the longblock i put in was supposedly rated at 340.....the charged motor ran 399 at the wheels

340 flywheel prolly which is about 294 wheels

who says you cant run a centrifigural super on a carbuerated setup? its what we call a carb hat my friends. but any ways those pistons are sh*t any how yank the motor and put some forged dish pistons in and your set.
