[QUOTE="01blckcobra, post: 16324736, member: 92039"] 7500+ rpm put alot of strain on parts. Stock timing components work but recommend placing often to cya. Also you're going to have to look into better connecting rods, beefier wrist pins, springs and retainers. Upgrade pivot bolts, oil tensioners(non-plastic), ect... tensioner guides / arms probably be the only thing you don't need to upgrade. If you don't mind tearing the motor down ever so often and checking components, you can get away with stock. Only thing would upgrade is the plastic oil tensioners to cast or aftermarket. (ratchet style). (Aluminum block would upgrade pivot bolts) Also stiffer valve springs. (90 or 120 lbs. seat) Also an increase in oil pressure is needed, - upgrade rocker arms / followers and/or pump. If not running aftermarket cams and intake manifold, there's no point going past 7k.
