I know this is 18 years ago, lol, but by chance do you have that motor, the 22035570 motor?Don't know the cfms but the mid 80s Olds Deisel Cutlesses had a fan that outflows any that Spal make and it will bolt right in to a GN shroud. In fact, I have one here waiting to go in. AC Delco PN 22035570. I would have installed it by now except that when a friend added his he says his 140 amp alternator won't keep up anymore and he's having to get a 200 amp model. I'll have to wait a while I guess. Also besides the alternator, he said he upgraded the wiring to 8 gauge. eek!
