I shipped him my stockers today, he's supposed to send the pwk's tomorrow.
He measured them and said they were 1 5/16", that looks like 33mm. I sent him some good carbs minus tors that were already jetted for Pro Circuits, stock intakes with cross over tube, air box front with billet K&N plate and good K&N filter. I even threw in a nice stock head because I knew he was losing a little money.
He said he had good low end but I'm afraid they'll be a little big for my mods, so I might be trading them for some 30's one day.
