Carb suggestion for 360
For drivability you can't beat a 600 Edelbrock.
But he built a 360..
If he wanted to use a 600 ish carb,, he shoulda built a 318, dontcha think?
If he put all that money into building a strong motor, why not finish the deal and put a reasonable sized carb on it, that will awe him,, and anyone else.. It's like putting on single exhaust... ?
And as to the "crispness" of the smaller carbs,, In my experience a little time spent with a smaller squirter, and/or smaller primary jets, will make the big carb as "crisp" as the smaller carb.. jmo
hope it helps..
