I got a pair of pretty nice stock cylinders that I plan on using for my drag build this winter. I'm for sure using these cylinders no questions asked, but I'm trying to decide if I want to do a 4mil or 7 mil. I already have the person picked out for porting.
What special things need to be done on a stock cyl setup to make the 7 mil work. I haven't researched it much. I'm assuming just as thick as you can go base gasket, obviously porting, trenched cases and cut domes for the 7 mil? Would like to learn.
