Default what piston with a 408 and l92

I am going to use pump gas and just a small shot of nos, I was planing on using some diamond -2 dish but the builder is telling me that 11.5 is too much for 93 octane... diamond will cut out the vavle relief for me but befor I order special stuff I figured I ask here.

maybe there is a better piston for this combo?

Your builder didn't ask about your cam? You need to tell us what your dynamic compression will be. Not static.

i definitely don't agree with 11:5 being to much compression unless you're running a very small cam that has your dcr over 9:0. i have 11:7 scr on my 408 but my dcr is still on the low side (i think around 8.5-8.6 or so) and i spray mine (only 100 shot with pump gas in the stand alone and 4 * pulled) and it would probably handle a 150 shot on pump gas but i'll put in 104 or 110 for peace of mind.from what i understand the l92 setups don't like quite as much scr/dcr before having to pull alittle timing but that is just from what i have read on here so take my opinion as it is.
