Track times in here 383
HOly **** buddy you need to throw in a stall already!!! That car will be much faster, **** you might break the 11's with just the stall. 
You have a few more months til summer is here, so get that stall in there, lol
You have a few more months til summer is here, so get that stall in there, lol Im suprised you went that fast with factory heads. Motors only go as fast as the heads allow, and with factory castings-that isn't much. It appears you have a very well built motor if yur running these times with factory heads...port and polish the stockers, and like the others said get a nice stall and you'll cut WELL into the 11's...hell, if you've got forged internals you could spray it too and have one raped ape...

I went 12.20s with stock heads,hot cam,10:1comp,stock converter and trans,4.10 gear with my 383. Then after ditching the 4l60 for a th400 I was able to go 11.76. Put a converter in it you will love it.
Wow - you picked up a ton of ET with the TH400. Exactly what I'm hoping for as well.

With the right heads and a 32 to 3500 stall you'll be very very low 11s or in the 10s solidly.
My previous motor a 383 (which only had 9.8:1 compression) was outfitted with 190 AFR heads (old style) a GM 847 cam w/ 1.6s, full exhaust, 3000 stall and 3.73 gears, ran 11.50 to 11.30s depending on the weather. My new motor is using the same heads (with mild work) with a custom cam and 11:1 compression , all the rest is the same and it is scary by comparisson.
I think youre combo is running very nicely.

Nice times for stock heads. Id say hit it with some spray and leave the heads stock for now... Since your all forged a nice plate kit from n2o outlet would do wonders...

Not sure how large of a shot the plate kit will handle I was under the assumption of around 200, but I have not looked in a while since funds ran low. I have looked into them though.
Well, with a converter you'll need stickier tires. Then you'll most likely need suspensio. I'd guess a .5 second ET drop. Then if you get nice heads you could see another nice gain, add more suspension. Then you can spray it for 150 and dip into the 10's, more suspension. I have a 396 with stock ported lt1 heads and it ran 11.4x on motor, 75 shot out of the hole ramped to 150 = 10.4X. Let the addiction start, I just dropped $800 in parts this week alone.
