Only reason to switch to Chevrolet is to get more power, more RPM, no oiling system troubles, fewer exotic parts, less mandatory machinework, better overall reliability. :boxed:
I think we can see Brooski's priorities. :rollside:
Seriously, there is head machine work, and usually additional drain lines from the heads (never saw them on valve covers before) to the lower block and often restrictors in the oil passageways, all to help stop the problem of the Olds pumping it's entire oil pan contents into the heads at moderately high sustained RPM. Without all the other work, you'll only succeed in filling your puke tank to overflowing, then continue to make a mess, or drain her dry. :cry:
