Best Carb Option For 1600 Escort

[Royman]

Hi, Just brought a mk2 2dr 1600, stock standard. I want to get some performance out of it while leaving the original engine in it. Ill be fitting extractors and exhaust, will be getting the cam done (any suggestions for that would be great) and looking at different carbie options. Im on a bit of a budget so would like to go for second hand or recond carbie and manifold. Just wondering what will give me the best performance for my $$ (don't want to spend much more than $1000.)
Any suggestions would be great...
Cheers Guys.
