1970 Duster project in Sweden

The 360 will go together something like this

Stock crank, rods & bore (honed by me)
All new bearings & oil pump
Ported (by me) 3769974 heads - Mr. Gasket 1121G
Speed Pro H116CP pistons
Compression Ratio : 10.05 : 1 (according to a calculator)
Xe268H and matching springs, new lifters, chain and gears, stock rocker assembly
LD 340 Intake
Street Demon 625 carb
PerTronix Ignitor II Billet distributer & Flame Thrower coil
Long tube headers
2.5" Dual Exhaust / Super 44 Flowmaster
8 3/4 with 3.55 or 3.73 and suregrip
3000 stall converter
275/60-14 rear tires
Isn't the 625 carb a little on the small side? Wouldn't a 750 - or bigger - be 'better'?
