1200gxman, I suggest you do some reaserch and
read this. webbers vs dellortoes, really there is a sh!t of difference because for every thing that can go wrong with your dellortoes there is something as stupid with webbers. How do I know this? I am reading a book that is how to tune and rebuild BOTH of the carbs and I have just finished the comparison section of the two.
It all basically boils down to preference and if your tuner says get the dellortoes, then get the dellortoes because he would have picked them for a reason, even if its only because he prefers them.
I have had a pair of webbers but my ute has dellortoes on it now (came with them) and it goes fuking fantastic... BUT it is totally useless putting these carbs on a stockish engine...
EDIT: check the prices on ebay because that seemes a little high, I would expect an almost new pair for that.
