T and T results

Well I got the car to the track yesterday. Slightly disappointed.
I got 2 runs in, could have had 3 but I screwed up. I was to tired after working all night.
Here's the second run times
60ft. 1.943
330ft. 5.526
1/8 8.515
mph 81.67
1000ft 11.132
1/4 13.371
mph 100.14
Leaving the line at 2000 rpm
I need some help tuning this thing, I beleive it should run low 12's high 11's without a problem.
There is a problem that came up yesterday with the carb. Seems it wants to load up at idle sometimes, and others it will idle at 2000rpm. I think the floats need to be rest, I'll check that first.
Here's what I know about the engine, or was told by the previous owner.
340
13-1 compression, I did a compression test and pressures were all around 215-220psi.
mid 500 lift solid cam, with roller rockers. He never came up with the cam card. I hvae to get out the dial indicator and check this.
Ported x heads. o-ringed.
850 holley.
I put in a 3500 stall converter, but I think that's a little low and I am going to try and get the 4500 from my friend.
manual reverse valve body.
4.10 spool in the back, running 325x50 15 BFG dot comp's
Timing I set at 36deg. It has the Mopar race dist.

The 60' time is higher than I thought it would be, but it didn't feel like it was spinning.
Any sugestions would be appreciated. If you need more specs on the car, just ask.
Thanks.
