Too much Carb for a 318?

I'm pretty sure I know the answer to this, but I am (like most of us I think) trying to save a buck.

I was planning on a 650 eddy for this build, but I have (in parts) a holley 750 DP.

The build is

318 w/ 360 heads.

forged aluminum pistons that put it at right about 9.8 to 1.

isky cam .485 lift, 280 dur, 232 dur .050, LC 108

M1 single plane intake

doug's headers.

So, is a 750 DP too much?
Pretty sure it is, just wanted some feedback.

Thanks!
