Installing a 1'' carburetor spacer

got another question for you guys, I just bought a spectre 2 in 1 carburetor spacer for my truck at auto zone, says it adds power and fuel economy (not so sure about that, but i thought i would try it) and its 1'' tall, now i have a 700r4 transmission, WILL this mess up the TV cable, being as the carb is 1'' higher, thus changing the geometry a little bit, what do you guys think, do these make any difference? comes with a 4 hole insert for low end power and open insert for high RPM power, going to use the 4 hole, if the butterflys on my carb will allow it. it says right on the box that it fits edelbrock carbs. thanks

carb spacers definitly work.. they give the fuel a better chance to atomize thus improving power.. as far as the tv cable goes it depends on if you have a bar style one or if its acually a cable.. the bar you will have to tweek a little to get your passing gear to work right.. if not it wont downshift as soon. if its a cable then you dont have anything to worry about... i have never used one from autozone so i cant guarentee that its gonna work but its definitly worth a shot.. its only a few bucks waisted and i would like to hear the review.. lol

Ive got the one with the adjustable ratchet out clickity click thing lol if that tells you anything I didnt know there was 2 different styles

Carb spacers work by giving the air and fuel more time to mix before being burned and on Carbed and TBI engines they work good. On MPI & SFI, they do not work at all....

On your truck you should notice a slight increase in HP, but a nice bump in torque. IMO its a good upgrade.

if you bought the plastic 1, take it back.. seriously.. they crack very easily.. they sell an aluminum 1 that is 10 times better.. if you have/get the aluminum spacer, put 2 gaskets on the top and bottom.. they're not always 100% flat

hold it there skippy.. i doubt you have the clearance under the hood of your land yaht.. if i remember correctly, you have very little clearance under your hood

Not saying I would do it. Just saying it's good to know for down the road. I'm going ot measure it though. If I have a little wiggle room, I'll consider doing it, after it's running properly.


IIRC, there's an inch or two to mess with.

you would just need to get a shorter air cleaner if you didnt have the clearance..

so will the TV cable be affected? if so, will i be able to re set it and be fine?

true.. the small edelbrock breathers are a whole lot shorter


you can easily reset your tv cable.. if it was a ford, i could walk you through it, i forget how the chevy's go

i know how to set it just wanted to make sure i dont screw up my tranny, by installing a 20 dollar part

nah your good.. youll be happy with the benifits..
