Remember that everyone will have different jets and the carb will be tuned different depending on altitude and humidity and the likes. What runs good for a carb here in Edmonton probably wont work as good for you.

My 10.7:1 351W had a 750DP with 76/78 jets, 6.5p/v, and 32squirter (but I think I redrilled that bigger), with a 50cc pump.

so... you'd be better of with a 5.5 PV.. and spread the jetting a little more... the PV is the same as 8-10 jet sizes... it's really worth it if you can get some time on a dyno with an A/F monitor...

did you get a copy of the A/F ration thru thr RPM range?
on a DP, you can unhook the secondaries.. get the primary side right.... then hook them back up and tune the secondaries ;-)

Honestly, go to a Chevy site and post the same question only say a 350 with the same hardware and you'll get a billion responces.
