what,if any,difference will replacing the smaller TB on my 89 Bll with the larger TB of an 87 Bll make?? except for more airflow into the engine??

The throttle plate will weigh more, so the pedal will be harder to push.

You will gain a little bit of power. probably not noticeable except at high load.

That's about what I thought so i did the swap,no real power gain . I noticed a drop in the gas mileage though. My 89 has 324,000 and some change and still runs great. Thanks for replying.
