the way i personally like on the 302 is the AFR 165s 58cc chamber, standard bottom end with a steel crank steel rods and forged pistons.... make sure to use good new bolts for assembling the bottom end as well..... also a main stud girdle can make that bottom end a lot tougher.... i would reccomend having the block line honed while its being machined.... fords sometimes will get a little off line on the mains and chew your crank up... make sure to buy a new balancer as well.... old ford balancers always are off by the time you get em.... of course all this depends on your budget.... another nice addition is a retrofit roller cam with a 351 firing order, it makes the engine a little more balanced on firing
