Large bore short stroke is where it's at for a drag race engine. The piston manufactorers don't recommend a longer then 4.0" stroke in a L-92 or 3 block for power adders. The top ring land gets close to the top of the piston. The short cyl. bore of these blocks with longer storkes will have piston rock which effects cyl sealing and relibility. Its like the old Ford 5.0 debate between 347 and 331 engines. Hell build one with a long stroke and see what happens. I'm going to stick with a 4.0" stroke. Scat recommends this as the max stroke for these blocks.
