i was reading about those, looks like the kind demons had that option. i also seen you could have the body machined for the sleeves probably like what was done to yours. looms like other than interchangeable holley parts there isnt awhole lot available. if i can change this one to blowthrouvh it may change the direction of my 406 from decent na street strip type motor to something with a bit more power
