Would it be worth doing? I know a welding professor and I'm sure he could weld aluminum,so my question is......If I cut open the inside of my stock runners and had him weld them together in the middle to make homade siamiesed runners would it be benificial?
$300 bucks is pricey when compared to $20 for his welding.So should I save up for SLP runners or fire up the welder?

neither , unless you have a larger cam, siamese runners will not benefit you.

 

Sorry I didn't mention that, I'l be using the ZZ-4 cam.

 

A 350 with a ZZ4 cam and 1.6 RR is a good combo for what you want to do, IMHO.
It is a good idea, maybe I'll do it too.
Let us know how it works out.

The SLP runners are not only siamesed they are also a larger prot. I port matched my plenum to match them and I had to enlarge the openings on the plenum not only just the center section that is removed on the SLPs Also dont forget to port match tha gaskets. I think, speakinf from an engineers point of view, if you dont remove that you are just causing more turbulance going into the runners and actually reducing flow.
