carb size recommendation

its time to replace the windsor engine in my fox

the motor I am installing is a 545 with P51 heads' cam is a Kasse spec. comp solid roller valve lift 757/751 gross

tappit duration @ .020 lift is 306/322

duration @ .050 273/284

lobe seperation is 110.0

what size carb should I use? I have a 1050 gas domi and a 1250 APD alky domi. and a 1400 SV1 or should I use something else?

also I need recommendations for front coil over spring rates. i have 150 lb springs in it for the small block

I would contact Prosystems and let them tell you if the SV-1 will work. I love mine!

i would say time slips would show something like 1150 or 1250 best
