I know this could lend itself to being a HUGE topic, but I need to start budgeting to replace my carb on my (now known to be) factory 318. Thing is, it's not wearing the factory carb now - it's got a 4-barrel on it. I know it's been modified - besides the 4-barrel, it has a full set of headers, and aftermarket valve covers (which in itself means nothing, but could mean that other things internally are modified.) And it's obviously been yanked, as the A/C was removed and the block was painted red.
SO, I probably need to stick with a 4-barrel, but I know NOTHING about judging CFM's, functionality, etc. I don't want anything fancy, Hi-Po, or high cost - just something to replace the worn out hunk-a-junk that's on it now.
Any idea where to start? Any idea on how to determine what's on it now with relative ease that might give me some better ideas?
