Don't know how he wanted to do it!!!! But then I don't know why someone would want to run a blower on a slant six either!!!!! What I do know is that a 3 stage retard box and a good ignition that is compatible with it is a lot more accurate and tuneable then a $39.00 vacuum chamber!!!!! Not my car, and I'm not buying the parts, guess he'll do whatever he wants.... As we all know, cheaper is not necessarily better......just cheaper....
