Size of TBI
Even though this isn't an F-body question, I know you guys will know. I have a 1988 Chevy pickup with the 4.3 V6. What is the throttle bore size of the V6 TBI? Is it the same 1 11/16 as ours?

Yes I believe it is. I think GM used the same TBI TB on the 4.3L TBI, the 5.0L TBI, and the 5.7L TBI. But they used the 2" TB on the 454 TBI.
