Could a 90mm TB fit on a 4.8 if so where should I start looking for one??

 

I just ordered an NNBS four bolt intake for my 4.8L so I could run my ls7 90mm throttle body. There is no point in running a 90mm throttle body if you are going to use a 78mm intake manifold. Are you looking for a dbc or dbw throttle body?

 

well whatever is going to give me the best hp gain! how much did the NNBS intake cost you?

 

I bought it on ebay for $175 complete with fuel rails and injectors.
