I've ran a low 10 second 440 for years and when I wanted to step it up I built a low deck 511. I used a Hughes girdle, Molnar crank and rods, 11:1 compression so it would run on pump gas. Unported Indy -1 heads, 640 lift Bullet cam and Dominator carb. Best run has been 9.62 @ 137 in a 3200lb car at sea level so with the extra compression and a roller cam I'm sure you would get there performance wise. Despite being sonic checked good, the first one split a cylinder after a short time so I half filled another block and its been ok so far. My biggest regret is that I went with a low deck combo. If it splits another block I would consider an aftermarket block but as the RB blocks are starting to come available again, the choices for an aftermarket low deck block are almost non existent.
