I have a 1980 cj7 with 35 inch tires and 4.56 gears. I am looking to replace my tired 304 with a 360 but as most of us are im on a budget. I will do a basic rering job with new bearings and etc. I am reading that alot of aftermarket timing chains have casting flaws. So is there any recommedation to a certain brand of timing chains and how do you guys feel with the summit 8600 cam and lifter set. Any help would be appreciated and recomendations with the cheap rebuild thanks
