I'm thinking I'm gonna stick with the 292h I have just because I already have it and I want to stick with hydraulic. I'm not to worried about the lifters floating because I won't be running in the higher RPM much. As you guys can probably tell I'm still a newbie when it comes to engine building, first one! Thanks for all the help. F-bird88, if I want to use your first combo with 10:1 what all do I need to buy and tell my machinist to do?
