Seems a little slow...

I wish i had your car set up.
That's a great combination and i wouldn't change anything.
First things first.
Your short time is way off.
The two things that control that are your timing and carb.
What distributor are you running and what is the total timimg set at.
ALSO>>>does it have the total timing in by 2500 rpm's.
You want to be at full advance before it hit's the converter so it will give you the fastest 60 foot posible.
Your carb needs a bigger shot of fuel,so change your pump shots to a bigger size.
Set your carb up like this.
71 jets \\ front
81 jets \\ rear
35 pump shot front and rear
pink cam set up.use hole #1 hole on carb and use the # 2 hole on the cam and set the arm under the front excelerater pump for the right amount of lash.A little looser then you would think.
I will have to check my holleys but i think it's about 5 thousands space.
The back pumps(secondary's) lass is a little tighter and adjusted to zero.
lash.
Don't change anything other then the intake \\ use the victor intake.
Try to use this set up even before you change the intake back to the victor so you can see the difference.
The only problem i see with your parts selection is the 1.6 rockers.
Your lifting the valve way higher then the heads will flow i would think.
Did you get the heads flowed on a bench?????
If you did post the flow #'s.
Good luck.
I think your car will pick up at least 4 tenths or more.
That set up should go high twelves tuned in.
What sea level is your track at?????????????
