which carb adaptor
 

There are so many different carb adaptors. I just ordered an edelbrock air gap intake which accepts square bore carbs, but for now i have to stick with what came on my 1989 350 mag...I know its spread bore, I think its a quadrajet. Can anyone point me in the right direction or tell me which adaptor I should get? thanks Harry

From what I've read, everybody who has used carb adapters has had problems with uneven fuel distribution.
Save your money for holley carb.

I would love to switch but I can't for a little while and I would like to use my boat.. For when I can which holley carb should I go with its a 1989 350 motor with vortec heads and an edelbrock air gap manifold.

I would think a 750 would be enough carb. Watch the classifieds and ebay. a lot of people move up to a bigger Holley on the big blocks that come with a 750.

I thinkEdlebrock makes an adapter. They should be as good as anyone.

A 650cfm should be plenty of carb. Stock is 600cfm.
