I'm looking for a place to port/siamese my friends new TPI parts. He has SLP runners (2nd design) and TPIS big mouth intake. He also needs the Plenum opened up for a 58mm throtlle body. ...... He would like the SLP runners nearly fully siamesed or fully since the car will be supercharged and I don't believe having them fully siamesed will affect the lowend since it's supercharged anyways. Basically he wants it all opened up as much as possible. Since all this will be mounted on a 395 stroker. ....... Any recomendations?

Problem there is it seems he only does plenums. I need the whole system punched out. Not worth it sending individual parts to various people rather just have one person do it. But thanks for the link.

You can do it yourself with a die grinder at the top and bottom of the runners. The only way to do it all the way through is to cut the runners apart and then weld them back together after the work is done. Jerry did that with the runners he made for Kevin and Don, but decided afterwards that it was just too much work to do any sort of production run. Using the die grinder on the top and bottom of the runners will do as much good as openning them up all the way through. The main thing you are trying to do is move the "tuned length" up the rpm band.
