so im lookin into gettin a 1 inch spacer for my TBI. I would like to get the kind that spin the air inside for a better mixture and blah blah blah... my question is, do i need ANYTHING else to complete the job? Fuel line extensions, the throttle cable long enough? anything need to be done? or is it just a bolt on operation?

 

i had another thought, ive seen wooden spacers as well, any advantage to them other than heat? And could I make one of those? Im very good at the whole carpentry trade, mostly the fine details...

 

The TBI is not like a carburator and is not subject to the heath soak problems that affect a carburator. A spacer makes the plenum larger and may add power or may lower power, but in any case it won't be anythingto write home about. As far as sticking spinning stuff or any aother gizmo in the air passage is a bunch of BS, and if anything it will cause a power loss.
