There you go !!! 11 to 1 compression and ported heads , my 360 heads were stock and I am lucky if the compression was 8.5 to 1. I went 11.30s with a 9 1/2 to 1 340, 557 lift cam and ported J heads. Now I run 10.80s with a 9 1/2 to 1 compression 410 inch small block , 585/595 lift cam with ancient W2 heads
