Would a 750 single feed be too much carb ? Unsure of camshaft duration ??:confused1:

What manifold do you have on it now ? Looking back on your posts, You have received many opinions on carbs. What do you want to hear?

 

[moparnut74]

Edelbrock Performer aluminum manifold.

For the street a vacuum secondary works best. Some people prefer Holley, some Carter/ Edelbrock. Carter which is now reproduced by Weber/Fiat for Edelbrock and was OEM on most models back then. I run a Carter Thermoquad on my 340.

I far prefer the Proform series carbs either DP or vacuum secondary , I would use a 650 typically on a 340
