Got a new holley 650... now what?

[71383bee]

Ya I got it from my local carquest I deal with, they had a couple decent deals on carbs this was the one the other was an edelbrock 750 avs style.. But after doing some research on here everyone steered me away from the edelbrock and I grabbed the holley from them because some older gearhead guy that frequents there told me it would work great on my car he had one on a 440 drag boat. I am not concerned about plumbing it if it would work but it really doesnt seem like its going to be worth it. There is no provisions for a pvc. I think its a non emissions type of carb for like a hot rod or boat like you say. Ill just get off my wallet I guess and get them to order me in exactly what I need. Man this hobby is hard on the young mans pockets! hehe but its worth it right?

This hobby and cheap do not go together well!  There are deals out there though. 

For sure that is not a high performance carburetor there.  That is a stock or stock replacement carb.  That style there I believe is the 4160 style. 

I got my 650 mighty Demon from Don at FBO.  They are pricey, but I can honestly say that I have only had to do a minimal amount of tuning and the car runs excellent. 

For your motor I would recommend either the following:

Holley 770 Street Avenger

If that is too much the 670 will be just fine...

Or the 725 Road Demon is also nice...

For ease of tuning in your case I would stick with a vacuum secondary.  If you had a stick and/or are not afraid to tune a bit I would definitely recommend the double pumpers with mechanical secondaries!
