I have a similar setup. All caltracs. 3700# mopar 340 +.030 street/strip Ati 8" converter, eldebrock heads, Vic single intake, 850 Holley, headers, full exhaust, 10.20/1 compression 391 sure grip rear m/t et streets runs 11.40-11.60 year round. I think your hp is a little low at 350 12's is prob correct for the hp. The slide rule shows mine around 450 hp @ 3700# to run what I do. With that said the best et gain was in the converter. I have run a spool with 430 gears only made about .10 diff in et. 60 foot 1.56-1.59 with 430. 1.58-1.61 with 391 gears I would play with the Jets and timing, picked up a couple tenths there. Just checked with the slide rule 350 hp at 3200 pound should be 11.60s at around 112 now of course that is at sea level your 60' is bad. Timing,jets, converter, gears, my converter flashes to 5800 shift at 6200 finish at 6100
