I just ordered thier new 285 0607 cam and 26 lb springs, ss valves ect.. This cam should sound pretty wild with 250 duration...
Are you running a billet rod and flywheel??..if not I'd suggest a billet rod at least if your gonna put a bigger cam and run more rpms..
PS save yourself some money and get the mikuni off ebay for around $30, same thing these places sell for twice as much..
