Under $4k budget build LA360 build

I haven’t gone that far yet in the combo department. At this point I only know 2 things for certain that I’ll be using at this point. I have a .40 over 360 with a stock cast crank. I have a set of 974’s that I’m going to try and machine myself a bit... nothing crazy and I might use them, but I have realistic expectations. Stock rocker assemblies that I hope to use, but know that I may need to go a different route depending on cam selection. I like the idea of either KB 107’s or Power Pro pistons H116CP.

I’m lost on how you came up with the stall and rpm numbers and tire size from. I apologize.
