Mines a 408 in a 69 Dart street/strip, 3300#. K-1 steel crank,Comp Star 6.125" H beam rods, Diamond 20 cc dish pistons, ported Edelbrocks, Victor 340, Bigs 950 HP, Hughes flat solid, 260/264 @ .050, .626/.633 lift with 1.6 rockers. With no tuning it ran 6.61 @ 102.24 (1/8) on the only pass I've got it to hook. The compression is only 10.9-1 so I run it on pump 93. It should run mid 10s when it's tuned.

My old hydraulic cammed, pump gas 340 in the same car ran 11.62.
