Have i got it right? 10s or 11s

The combo at the beginning of the post would have run 10s Our 67 gt has that exact same build with a little less compression and it went 11.01 on its very first pass on the motor w/ 4.30s on pump gas and a 28 in tire with a little more weight than you have. Havent started tuning on it yet though we will soon
