5.9 build for a ....D100

yes
but at 62cc, you are gonna have to co-ordinate your parts pretty carefully for 91 gas, and to your elevation.
For closed chambers and tight Quench, your pressure limit for 91 gas is about 165psi.
For best results, the subsequent Scr needs to be co-ordinated with the EFFECTIVE DCR, and the cams ICA (Intake Closing Angle).
So if the engine is operating at sealevel, it will be able to operate with LESS Scr than one at some higher elevation.
The target is always the same; namely an Effective Dcr of about 8.0..
So;
1) you sortof have to know at least about, where you want the power to be.OR
2) You have to sortof know how much power you want, OR
3) you sortof have to know definitively, the application.
But, for best results,nothing can be calculated until the operating elevation is known.

So you already gave us #3, and sortof #1.

looks like my area is around 900 feet or so above sea level for elevation.

honestly for power level, I am looking to Max it out while retaining drive ability, and be able to cruise between 60 to 75mph. I like 0-60 performance more so than top speed. I don’t mind something that doesn’t idle like stock, but certainly don’t want something that is a dog off the line. My goal is to have an optimized combo for the application rather than be dead set on a number for HP.
