Default RE: Replacing carbs

Depending on the carburator you purchase some already come tuned in the box so you may not have to adjust your carburator.
I suggest you read this http://www.mustangsteve.com/intake.html then follow up with your carb replacement as followed its a straight forward swap mostly just make sure you get a good seal on the intake manifold.

Members her seem to enjoy both carbs either eldelbrock or holly.I am running a 4 barrel Holly i havent tried eldelbrock but i would like too. Just make sure you have the right cfm. I believe you can get more out of a holly it has the ability to be tweaked and such for performance where as eldelbrock is more hassle free just bolt on and go.

Any advice on what cfm I should get? (I'm pretty new to this and I don't have a dad to help me with all this restoration)

Looking at the prices vs. my current income I think a 600 cfm should suit me nicely. Intake advice?
