If your interested installing a 4 mil crank (yes it will increase your displacement) and might bump your compression too. It’s all about how you plan to set the engine up…Go long rod or short rod? 10.5 102 cp piston pump gas deal Is a good choice- web cams can give you top end advise/get what yah need. If
Upgrading valve springs ,….better valves ,HSR ,a billet middle drive wouldn’t hurt. Lots of choices -4 mil crank will wake your ride up if done correctly! Best of luck with your build!!!
