Plan on putting on 200-250 shot

Long story short, sold Super Ram and going carb after car off road for a few years.

Which carb should I choose to suit my build? What cfm should I be looking for? 750, 850?

Also, spacers? Since nitrous will be plate at 1/2", should I also grab a 1/2" spacer? 4 hole spacer vs open spacer?

A good 750 should drive great. Ultra, HP, AED, Quick. If you turn this over 7-7500 maby look into a larger setup. On a dyno definitely a 850 but if you are gonna drive this thing a good 750. make sure you have plenty of pump with the spray.

BTW nice build best all around street head out there. Should work good with the single profile cam.

edit with spray you might consider a 112 lca
