I run 11.2 with a slightly smaller cam 244 @.050 intake I have about 200 cranking psi with a 4,400 stall 3450lbs demon with me in it. I think you will have trouble with 93 pump. The biggest things you can do is obviously no heat crossover, fresh air intake, keep the fuel as cool as possible, and use a very cold plug I use a NGK bpr9 I think.
