Mean 318...or stroker....hmmm

My other thread got out of control. So I’ll start another. 70 duster - vehicle use street fun some drag racing a few times annually. Current setup. 4 speed, 8.25 rear with 3.73 gears 750 holley, Weiand action plus intake, dougs headers, 360 heads 1.95 intake Valves have some porting done 63cc chambers, bored 30 over Stock low compression pistons 0.102 in the hole giving poor compression around 7.8:1. Cam Crower Hyd flat tappet 224/224 .465 lift. Crank was ground 0.010 on mains and rod journals.

I started out looking to change timing chain as it was lose/worn and went deeper to find out the story on the engine as it was new to me. So I end up looking to do a bit of a refresh and get some higher compression pistons. I hope the block can cleanup with 0.040 waiting on machine shop. Rod bearings were to the copper so crank may need more grinding. I started adding up costs for my 318 bottom end refresh and someone mentioned stroker which got the gears turning. With the machine work on possible cutting crank down, balancing etc A scat Pre balanced stroker kit may only be $500 more. Although a stroker engine will require other upgrades like better intake (the action plus has tiny 318 ports) Edelbrock air gap would be much better, cam upgrade to take advantage of more cubes. Clutch upgrade likely. But upgrades aside. What else would a scat stroker 390 kit require.
I think main studs (I’m sure the stroker will make 375+ hp fairly easy) So I’d like to keep it together, align hone as well. Any block clearancing for 318 stroker (minor or major work?), does the scat stroker crank need machining for pilot bushing for my 4 speed? Is zero decking the block necessary? Was looking at the dished piston option to keep it pump gas friendly. Compression likely around 9.5;1 with my current 63 cc heads. The zero deck will help with quench but not sure if quench is critical at my compression ratio or not. Okay let’s try to keep this on the rails this time boys.... lol.
