Okay so I decide to build a motor got my ws6 ! Didn't want anyone's opinions or anything just wanted my own project ! But since I've finished and decided to ask people I haven't been getting back the feedback I wanted so I wanted to see what you guys thought!

Engine ;
421 CID Lq9,9:1, with 244/258 on a 114 custom cam, Cnc ported stage 3 243 heads, Ferrea valves, PAC springs, tool steel retainers, mahle forged pistons, scat rods and crank, ARP 2000 bolts, cloyes timing set, melling HV oil pump, edelbrock super victor intake, elbow and FAST 92mm throttle body,Texas speed push rods, 1.72 comp gold rockers, act twin disk clutch , 80lb injectors

My plans are Togo boost and I wanted to ask what's the boosting potential , pros and cons of a 421 stroker ! Just your ideas on my overall build ! Shitty build or what ,

If you going to boost it I'll stay 4.030 bore and max 4.000 stroke on the crank.
4.1 stroke cranks pulls the piston a bit further more out the skirt. LQ blocks don't have the longer factory sleeves in them as a LS2/LS3 does

I thought the LS7 was the only one with longer sleeves since it was the only engine of that era to come with a 4" stroke crank. I might be incorrect doe.
