Switching from EFI to carb. Who do I know what to pick? Like the choke type and the style of secondary? I know that i want at least a 650 Holly.

Quick & Dirty Carburetor Sizing

This is a real quick and dirty formula for figuring carburetor CFM requirements for a street engine. This "Ballpark" method is very useful at the swap meet, parts store, or when impressing friends and family.

Take the engine displacement and multiply by 2. Then subtract 15% from the total. For a little healthier engine, subtract only 5%.

This a real ball park formula. For a more accurate calculation, see the Carburetor Sizing Calculator. But, this is still a good formula for general sizing purposes.

d = Displacement in Cubic Inches. (d x 2) - 15% = CFM

EXAMPLE: d = 350 (350 X 2) = 700 (700 - 15%) = 595 CFM

right now stock bottom end 302. looking into getting some TFS heads, i have a TFS stage one cam, long tubes and 150 shot of nitrous as far as the engine goes. Thats about it. Right now I have 351W heads, cobra intake, TFS cam, 30# injectors w/ matching MAF, 70mm t-body plus the headers and nitrous.

I would run a air-gap intake and a 600 DP.

I know the size I want but the choke and secondary type.

You already have nice parts on it. Why go carbed?
