sure there is alot more 12 second stock stroke 360 running around...or maybe there are all down in the 11 second bracket...
anyway...had 69 dart back in 80s
stock flattops, good valve job on J heads, mopar 284/484 cam...holley strip dominator intake, holley 750 dp..hooker 1 3/4 headers.
turbo action 3800 series converter with 4.56 gears and 9 x 28 tires...
ran low 12s in Vegas,,,hit 12.00 @ 110.00 in bakersfield back in 1986.
So 12s are pretty easly with an A body 360...
just make sure you get a good converter with gearing.
Tony
70 AARCuda Vitamin C 71 Dart Swinger 360 10.318 @ 128.22(10-04-14 Bakersfield) 71 Demon 360 10.666 @122.41 (01-29-17 @ Las Vegas) 71 Duster 408 (10.29 @ 127.86 3/16/19 Las Vegas)

12's with a 3.23 gears and small block is a little optomisitic.
i broke into the 14.9's with a 323". 188/160 318 heads. performance cam. 770 holley , single plane intake, low gears , 4 speed...sig
unless you add gear, then stroke it, or 3800 stall it. you wont get there.

I run 14.1-14.2s right now with a 2.76 7 1/4 while smoking the tires thru all of first gear. And I mean smoking... Looks like a burnout.. I get the feeling that 3.23s will get me 12.8-12.9s and have in fact been told multiple times on this board that it will

Up until 3 or 4 seasons ago (old age settin in) I was running with unported, ungasket matched, 1.88 vale 587 heads with 60 cc's. I ran consistant mid 11.70's with a best of 11.71. I made a switch to unported, unmatched 2.02 valve heads, after being told numerous times that it would not help and could possibly hinder unless I was running in the upper (above 6k) range). I did make sure to cut the heads to have the same cc's for apples to apples comparison. what did I gain??? Absolutely nothing. Using HD stamped rockers. I was able to pick up a new set of 1.6 roller rockers (Crane) so I went to work and installed them and ran them for about a season. What was the gain? A best of 11.69. I sold them before I had trouble with them and nearly broke even and still have the push rods. Well bout mid season i dropped a valve spring donut and anialated my head. As I had already planed a Hughes cam I ordered a set of stage 1 heads and that is what I'm running now. With a best of 11.39 Stock bottom end with a 10/10 shaft and wrist pins honed (unbushed) to run floating KB107's. The rods came from various engines some of which had been in a circle burner. It is running on a LD340 intake with no port matching with a Chuck Nuytten 750 Holley. 4.30 gear, 29.5X10.5X15 M/T slicks. The only balancing it has had done is hanging on the cherry picker. Now you know the rest of the story.
