5.3 to Trans Help

[Tuffy66]

OK guys I need a little help / clarification. I am going to put a 5.3 carb in my 66 c10. Im going to be using the stock 4speed transmission. Im curious if anybody on here actually has done it. I have been doing some researching and well its confusing, since some people say to do it this way and other says do it this way. And it seems most posts are "this should work in theory". So i guess im asking for a little help from someone who has done it.

Thanks in advance
