That would be a good scheme, Jerry. As you know (and as we've discussed here) GMC engines have a leg up in that they have an oil slinger and a wee notch machined (to catch enough oil to lubricate the rear main seal). You'll remember I suggested using the Speedi-Sleeve on the 235 or 261 and leaving the lip in place to act as a slinger to slow the flow of oil and deflect it around the machined recessed area there.
