Good Morning, I'm switching to a 700R4 trans next spring and I'm not sure which intake and carb to use. I have a 57 two door belAir with a (1962) 283 and a powerglide which really runs well. I've put 11,000 miles on the car in the last 2 years with long trips to the mid west and Canada, I live in Md.. The hard shifting and low MPG are getting on my nerves. I was thinking of going to a small 380 Holley.

I would think it would depend on what cam, if any, you have, what rear gear ratio, and what you are trying to gain. You will love the 700-R and if you don't over carb will get good gas milage and nice throttle responce 4 around town driving. I like Holly's because I can tune them easyier than an Edelbrock. If you drive the car most of the year a Holly will work well, if you plan on storing the car 4 the winter make sure the carb is full of gas and additive. That carb may sound small to most but work well with automatics. The 700-R gets it's message via the TV cable that runs from the carb linkage to trans, this adjustment is critical in trans operation. I have seen some Holly instructions say NOT used in overdrive trans but you can get around that. Make sure your '62 block will exept the rite starter also. Lon

If you go with a Holley and 700R4, you need to get this adapter for the TV cable. If the leverage is incorrect, you will fry the tranny.



700R4, adapter for a Holley carburetor to install the throttle valve cable correctly. Usually this part will correct a hard light throttle 1-2 shift. With this kit getting the correct geometry is easy.

Doug.....
There is a mathmatical equasion/formula that will tell you what cfm carb to run. I forget what it is right now. I will try to research it on the net tonight and get back to you.

I'm currently running a '84 Corvette 350 small block rated at 295hp. With my 700R4 and factory 3:36 rear gears.....I get between 19-21 mpg on the highway at 1850 rpm's with a Holley 600cfm. I don't have a clue what I get around town. With the 3:36 gears...She's not very quick off the line but does well on cruising. Talk to ya later.
