I agree on the rods unless you decide to put NOS on the engine...that is why aluminum rods are used..so it can take the shock and save the bearings from the hit blower and NOS ENGINES deliver to the bottom end...But I have to say current day aluminum Rods do not stretch and break like the older ones did...I run the newer set of GRP'S
You will see a quicker throttle response with these rods because of rotation weight.
go ahead and get you a middle of the road NOS cam that will not be a total dog on motor and will repsond to a small shot....gaurantee you will want to go faster once you get started...so if it were my engine I would go with the right cam, stay with the aluminum rods, good forged piston. get your ring gap correct and put you a 150-200 shot on it with an adequate fuel system
again JMO...Never seen a guy that didn't want more after a little time in the seat..so save yourself hassle and time and put the right parts in it the 1st time
