Well, finally have a new motor......went with the 5.7 Vortec Silver Package from Michigan Motorz minus the distributor. I'm keeping the TB 5 ignition system from the old motor. I went with the high rise aluminum intake with the Edelbrock Carb 1409.
I know I'll have to properly break the motor in according the service manual.......keeping the motor between 1500 and 2000 rpms, etc, etc. But I wanted to do this with the motor out of the boat, mainly for access purposes. Can the entire break in procedure be done with the motor out or does it need to see a load of some sort?
