850 dp to much?

I'm building a 350 for my camaro,

world sportsman II angle plug heads
288/294 duration 520/540 lift Hyd roller cam on a 110 lsa
1.5:1 roller rockers
9-9.25:1 compression ratio
I have a th350 w/ 2500 rpm stall converter.
3.73 rear gear
hooker super comp 1.75" primary tube headers w/ 3" true duals and flowmasters
I plan on running a weiand air strike manifold

my question, is an 850 double pumper too big for my motor? I have access to an 850, I plan to drive it every day.

Thanks for any input-

Eric

Too big, go with a 750 and it'll drive a lot better.

thanks, I have easy access to an 850 dp for next to nothing, but I don't want my car to run like crap!

Thanks again-
