    Unless you are going with forced induction and plan to make 1000Hp you wont need a new TB.. Edelbrock does make one that has a faster throttle response thanks to a better and faster throttle plate motor... But for the Small block arena you really are at the largest you can go with other than a custom one. But as i mentioned you really dont need bigger, just a faster throttle response thanks to the drive by wire controls.

    well the reason i was asking is that my tps went out and to get new acdelco one i have to buy the whole throttle body and its like 280.00 and i was like well **** if thats the case what the biggest i can get or a better one than stock

    If you go bigger with out increasing everything else it will actually drink even more fuel and loose power. and yeah the TPS is one unit on them, that is why i recommended that you take a look at edelbrock since they make a faster responding TB unit for the chevy motors, which means it will go better with less lag. Otherwise stock is plenty.

    X2 what murdog94 said. Stick with the stock throttlebody. I've read on this site and other places about people having nightmares with aftermarket throttlebodies. Goggle GM ported throttle bodies and look at the guys that offer ported factory throttlebodies for about the same price as a dealer .
