Are the stock injectors for a series one SC 21 lbs? Also since i'm running lean on the top end would I benefit more from bigger injectors say 24 or 26 lb or maybe just stay stock and get an adjustable fuel regulator? The car runs great except I'm runnin lean on the top end still.

31.

Why are you running lean? What have you changed?

They are 29lb, not 31.

I'll ask also. What have you changed? Fix the problem, don't bandaid.

so the stock injectors are good for how much horsepower then? I have almost fixed the problem.l I'm still waiting on my manifolds to come back from the shop and I fixed all my vacuum leaks.

When I had mine rebuilt the guy found they flowed 31 pounds. But maybe he used higher pressure.
