I have a fresh built 327 small block in my 67 Camaro and need a little advanced help from people with good engine and carb knowledge...
Here are the specs on the 327 build....

.020 under on the crank
bored .030 over
3.25 on the stroke
11:1 forged dome top pistons
2.7 dome cc
Gap to fit Molly rings
.016 on the deck clearance
.039 felpro head gaskets
So .055 total deck clearance
High volume oil pump
Comp cams flat tappet hydraulic 292h cam

64cc camel hump heads with 5 angle valve job
1.94int 1.6 exh SS valves
1.5 ratio full aluminum roller rockers
High rise dual plane intake manifold
Holley 670 street avenger dual feed carb
Holley high volume fuel pump
HEI billet distributor
MSD plug wires
Accel racing plugs gapped at .45
Electric fan
Electric water pump
1 3/4 long tube headman headers
2.5" H Pipe dual exhaust
40 series Flowmasters
Every bolt in and on the engine is ARP and torqued to spec
Cam is broke in proper with 20mins at 2000rpms and 10mins changing RPMs between 1800 and 2300
Initial timing set at 12 degrees and timing is around 36 degrees with vacuum adv plugged in at 3000rpms
I'm running a Borg Warner World Class 5-speed manual trans and a 12 bolt differential with 4:10 gears
My question/problem being, is my carb to small for this build? Ive adjusted the hell out of my timing and this 670 carb and it is a pain to get it to idle cold and by itself. When it gets to temp it will run fine at 1000 rpms and pull 10 psi of vacuum which is good for this cam. If I turn the car off then back on I have to sometimes hold the throttle to the ground to get it to start then it will idle normal again. It also doesn't have the crisp throttle an engine like this should have when I rev it. When driving it doesn't quite have that spunk I expected it to have. There's no hesitation when driving so I don't know where my problem is...
