holley carb choices

[silvermonte]

Hello, i was at an event the other weekend and ended up with an award for my choice of a holley carb. I went and talked to the shop that helped my build and pick out the parts for my motor and they suggested i get a 4150 double pumper 650cfm http://holley.com/0-4777S.asp . As i was looking thru my options in noticed the ultra 4150 aluminum line http://holley.com/0-76650RD.asp , is there any reason i shouldnt get the ultra as cost is not an issue? This cam is rather small and i plan to bump up the size down the road a bit better to match the heads as i think they a bit on the larger size for a 350.



the specs on the vehicle are

S10 truck that is about 3000 lbs
700r4 with 2300 stall and 3.73 gears in the gear
350 bored .060 with 9.5 compression iirc
heads are pro-comp aluminum with 210cc runners
cam is a comp cams XE268h
adv dur 268 280
dur @.50 224 231
lift .447 .480
