Blakcharger440 OP top fuel B Joined: Jan 2003 Posts: 2,410 Wichita,KS	Would I be better off going with a 5/16 or 3/8 pushrod for my engine combo? Here is what I have 500 RB Wedge,10.5 comp Cam is Hughes 579/587 256/260 Double valve spring which has pressure of 365 at .550 lift. Installed is 155 @ 1.880 height Would a thick walled,quality 5/16 pushrod do the trick or is a 3/8 pushrod the only way to go with this combo and just extra insurance?
