Iv been down the road, this is what you do,

leave the 2.80 alone, I had a 2,80 for a long time, but you do need to get a cooler running plug, I dont know the exact number but the stock ones are a "7" and you need to get "6's" in, that helps if your getting some knock, but the main thing that mad my car run hot as h&ll was the stock manifolds, get rid of them, nothing cools these engines better than a set of Long tube headers, I also have a Cobra "R" hood, with the vents opened up and man oh man does this hood dump hot air out the top even sitting still with the fan running, I can put my hand over the exhaust holes we relieved and with the fan running the air coming out would burn you left there too long when I still had the stock manifolds, with long tubes??? never,,,nice and cool all the time
