oil cooler

You don't need it. At all. My truck wishes it was abused so it got treated better, and it has never once gotten hot. It's just not possible up here.

I removed the oil cooler on all 3 of my swaps, and haven't had a problem yet. I just bought a blockoff kit from the dealer, which consists of blockoff plate, a gasket, and two bolts. The whole thing cost me about $15.00, mine was for a 5.7 so maybe yours will be different price.

Do the newer lines have a metric fitting? You could also just get some braided line with an fittings.

I'd run one myself. Oil should last longer cool. I'd be more worried about oil break-down than the motor heating up. Even with the factory cooler it'll run 250+* when it's 80* outside.
