Check Ebay, there are several aftermarket Throttle Bodies that are better than factory. The problem with TBI is that it's limited in tuneability after a while once you start getting into the more radical cam profiles.

Re: Holley TB

You probably don't need it unless your a high rpm turning 350

Re: LETS TALK CARBS

I am putting this car togther for my wife it won't be getting any more radical than the 350. which is 30 over double hump eagle heads and a good size cam. just wanted to make sure the cfm wood be enough for it. i want her to have power but be reliable enough to drive without any problems.

also the power windows dont work i check the fuse under the dash is there any or fuse or ? to check

Re: Holley TB

Don't spend the $ on throttle body. Spend on headers. Exhaust. Check power to motor if no power then electrical problem if power then bad motor

Re: Holley TB

I'm shure you will be happy to start tuning with it, the stock TBI ECM was a big headache for me too.

Re: Holley TB

I bought the HOlley TB only cuz I got a good deal for it. I pretty much did everything u want to a 305 but heads. I have a LT1 cam and springs. I think it was a good change.
