Hey Ed, Looks great! I am sure you = will find the=20 optimum length manifold will be

the exact length I made mine :>)=20 .

Can you tell me about this pourable = polyurethane?=20 Where did you get it?

How break resistant is it, such as in = bending?

Thanks,

Lonnie

So we hopefully will see what this = does in a=20 couple of days. Oh yes, the throttle body mount was = poured from=20 polyurethane plastic.
