why is the caddy 4.9 a bad motor? My buddy has a cherry 93 DeVille and the thing runs nice...
Good question, I actually don't have any experience with this motor, so we're probably going to find out why on the track. I haven't really seen any inherent design issues other than the iron heads/aluminum block and floating cylinders, but its not known for head gasket issues. I think a big reason that nobody likes these motors is that the power capability is pretty limited due to head and intake layouts and there is no aftermarket support.
In order to keep the oil pressure up on the track, and because we had to cut the oil pan anyway, we decided to give the whole system attention. We added some capacity, baffling, and a windage tray with integrated crank scraper, all made from about $20 in 16 gauge steel from the remnants bin at the local steel supply shop.
The 4.9 came with a remote oil cooler integrated into the radiator. We're using that system, but plumbing it to a Ford excursion A/T oil cooler. Pics to come on that setup.
