Hi again, thanks to everyone responding. Sodell offered a carb for shipping. The nova and I are happy. I know somebody thinks I am nuts for wanting one of these carbs (my wife thinks I am), but I wanted a progressive 2 bbl, I am little Rochester biased (from my Dads experience), haven't seen much of the Holley 5200 style carb anywhere I looked. I also wasn't sure if these would be big enough. They were also a stock peice for a 250. I know they were developed for emissions but is that going to hurt driveability? Hopefully I am happy with it. There is a reman carb for a 250 on ebay, I was very tempted but resisted bying it. Most varajets on ebay are for the GM 2.8L .
Now to make it fit. I have come to the conclusion that the 250 2bbl was only availeble as an integeral head.
Am I still nuts?
