I currently have a 2:80:1 Ratio rear. I am eventually going to install an Edlebrock Performer Intake & 600cfm Carb (thinking about a cam, but unsure).

Anyway, I want more power transferred to the pavement, what gear ratio should I go to? I was thinking of 3:55:1 is that too much?

Also what are anyones thoughts on Edlebrock Performer Intake/carb/cams? Likes/Dislikes? Hows Streetability? Should I nix the Cam and just do the intake & Carb in order to maintain a good Daily Driver?

Alot depends on what you're running for a trans, plus what your driving pattern is. If you spend alot of time on the highway, 2.80's aren't bad with an automatic and a vacuum secondary carb. If the engine is relatively stock, then I'd go with a good dual-plane and small (no bigger than 600cfm) carb with vacuum secondaries. If you like the retro look, a good performer is the Autolite 4100, on a Performer manifold with the "Edelbrock" ground off and painted corporate blue. If you are running a stick on the highway like me, the 3.00's I have provide good performance with nice highway manners. I have a few performance mods and use a mechanical secondary carb. If you don't spend alot of time on the highway and have stock in Standard Oil, then go with 3.73's, single plane manifold, etc,etc,etc.

PS, If you are using cast iron manifolds, consider upgrading to HI-PO repro's and 2 1/2" exhaust.

We have 3.50 gears in two of our street cars. They are highway driven and
it works well. It is a gear that in my opinion is not to high or low. I also
use the 600 carb. and a dual plane intake. You have the right idea. If you
do a lot of highway driving (every day 30 min to work) 3.50 may me to
much. We drove our car to LA from Monterey (8hr) and got 14 mpg. I
was happy with that. We have use cam in the .480 to .510 range in the
street cars.

definately get the cam with the combo or it will be a waste of money. it will be very streetable with the performer combo. and probaly even with the rpm combo also. i would just stick with the edelbrock performer dual plane manifold, itll give u more low rpm torque, its great. i have it but have a holley for a carb and a melling cam. but id probaly just buy the edelbrock combo if i were gonna do it again. like i said, very streetable.
