I'm thinking about changing my carb for my first
winter project.
I need lots of help because I'm just a new gear head.
Right now my car is pretty stock:289 2v 33k miles.
I do not want to build a racer i just want better
preformance. I also need one that is easy to install.
the HOLLEY carbs say" bolt it on and go".
Is this really true???

thanks for any and all info,

Jim

Jim,
I used a Holley 500 CFM 2V carb on many of my Cougars with 289 and 302. It is a bolt on and go proposition. It fits your stock intake and gives a substantial boost in performance.

I have also tried the 350CFM 2V Holley and find that it is no different than the stock carb in performance.

Edelbrock also makes a bolt on 600cfm that's pretty easy to install

I have much experiance with the 4412 500 2bbl holley and I would advise against it. Its a great carb, but a small 4bbl would be a better fit for a street car with better all around perfomance and especailly with regards to fuel economy. Also the 4412 only comes with a manual choke.

That said, the only draw back for easy instalation for the 4bbl is the need and expense of changing the intake manifold but 289- 302 intakes are easy to come by either new or used.

If your dead set against changing manifolds I would just use the holley 350.

A eldebrock performer with a 600 holley single feed, vac secondary,electric choke carb would be pretty easy to install and setup actually. Or you cant go wrong with a 600 eldebrock carb either. They are pretty much bolt on and forget them.mm
