I have a 1991 Isuzu NPR that has no engine or trans. While I was at the boneyard I picked up a rebuildable 390 w/aftermarket 4bbl intake. Now the Isuzu has 4.88 gears and 31" tall tires, no other gears are available.
I'm thinking of putting the 390 in there with a C-6 but I don't know if it will take the rpm level on a day to day running, or should I look for something else engine wise? Also the stock Isuzu diesel has 368 ft/lb of torque and I'd like more than that.
