Intake modifaction on a 2.8 TBI

If anyone would like pics of the swap, I have pics of the stock manifold and the modified manifold side by side and the finish product. For those who dont know, this mod is making the throttle bores from a 1 7/8 stock 2.8 size to the 1 11/16 size of a stock 4.3 throttle body, and using the throttle body from a 4.3 with the 2.8 injectors. It works very well, noticeable gains are unknown, but are very noticeable.
