which carb

I say go for the 600cfm. It's not too little or too much for the 289.

Go for the 600. I have one on my Cleveland in '65 and it works great. I tried a 750
and it was to much.

Same vote. If you would have less modifications, maybe Edelbrock 500 would do. With your mods, Holley 600 vacuum is probably the best if you like to tune it to match all the other mods.

Door handle first when cornering

Edelbrock 1405 or 1406. I did the 1405, and installed a manual choke. Hadn't had much luck w/ electrics. Works Great, and you don't have to adjust it every week.

How many pages of Holley parts do you see in Jegs?
How many for Edelbrock carbs?

any questions?
