try this link, its from the site, CHEVYTHUNDER.com, thats about doing a tpi swap, i used bits and pieces of info from there when i did my Monte ss 350 swap, i couldnt use the diagrams exactly since i did a speed density setup using many Maf parts(plenum, tb, etc) but it did help a great deal and it should help with what you need.
