mine weighs 3430 I have a 1978 std bore 360 that I put kb flattops in and R&R'd the stock heads - 1.88 intake valves and all.

even with a 200 dollar mopar 2500 converter I was 12.80 @ 108 with the 3.23 gears out back and a 26" tall slick

went to a dynamic converter, 24.5" tall slick and it goes 12.56@ 106

aside from the KB pistons it's a stock rebuild, and a mopar 474 lift cam


If i can go 12.50's with 3.23's and a stocker 360 you should be in the 11's with a big block...
