Small block + 4 speed build

My car was built to be a street/strip car and is a stick. The 360 stroker makes 550hp/5800 and 550tq/4400, it pulls to 6500 with ease and is built to run a 150 shot of nitrous. It has ootb trickflow heads, 11.1 compression, ootb rpm air gap with an 850 blp carb, a racer brown sft with 256/256 @ .050 on a 107 ls, .582 lift with 1.5 mancini rockers.

To me the easy button is to run some icon 9978 pistons Icon FHR Pistons IC9978-030 Fits SB Chrysler 408 Dish 13cc Bore 4.030. They feature a small 13 cc dish, 4032 forging and are reasonably priced. The downside is they sit .015 lower in the hole than the more expensive ic745 but to adjust compression/quench just get a cometic 4.080 head gasket in anything from .027-.032 (for the same price) to get to 11-11.2 or so compression. Use your heads and rpm intake, a cam from racer brown and you would have a virtual clone of my engine if that is what you want.
Yes this sound very good and sort of validates my power guess for this engine. So you have a single pattern cam from Jim, not long ago I used his 232/232 108 cam and was happy with results. I will probably get dual pattern cam this time with a bit less intake duration, tad wider lsa and .600+ lift with 1.6 ratio mancini rockers.

Thank you for pistons tips, I will look into it. I had zero problems with running premium pump gas at 11.3:1 static with that small 232/232 cam edelbrock rpm head 422ci 340. Ended up givng it 34 degrees duration with two light blue springs in the distributor.
