blower manifold ideas needed!

[buickstage II]

Hi to all,
as i just about have everything now for my buildup here in down under, im going to run a whipple blower, i have seen alot of manifolds that are used like from indy 3000 to custom sheet metal jobs.
however i still need to make one (could modify something, but want to make)

i have whatever resource needed to make up whatever. just want the "know how", on the in's and outs of your thoughts and knowledge, so im all ears.

thanks Simon.
