![]() Hi everybody, I have decided to go with the gears. But I don't know what kind of gear ratio i should get. I would like to go on the highway sometimes, but dont want to blow my engine up. So do you think 3.55's would be a good choice? Also, do you think I should get a posi? Or should I wait and upgrade to a nine inch later on and then get a posi with that. I will not be on the drag strip so the et times arent a factor. I also want to but a 600 cfm Holley carb and edelbrock manifold. Is that a good setup? Would my car be faster with the gears, carb and manifold? It has the stock 302 w/auto and the stock 2v carb. Thanks everyone.

![]() I agree, the 9 inch would be way overkill. Personally, the best way for u to switch gears is to buy the whole carrier....of the ratio u like best, with the posi already installed. Then u can put it in urself and save the installation costs.
I do not theink the 600 will be overkill....but maybe more then u need. I think the 600 will be a good choice for you...gives u room to grom in the future. With the gears u will feel the difference. Ur next best bet would be exhaust and/or a shift kit if u do not have one already. Ryan

![]() I use a 625 Road Demon on my 306 and its just right. On a modified 351W, I think a 670 Avenger or even up to 750 would be OK for the 351W(depends on mods). I assume we're talking vacuum secondaries here. They are much more forgiving due to the fact that the secondaries only open on an "as needed" basis. I would never put a 500 CFM on a 351.

![]() I agree that the 570 Street Avenger is just about right for the 289. I think a modified 351W needs more though.
