I might suggest a tuned port injected 350 out of a late-80's Corvette or F-body. The "TPI" makes extra midrange torque due to its design, and is the best truck engine GM never put in a truck.
Down low, a TPI 350 will pull harder than an LT1 or an LS1. A properly built TPI engine will feel stronger than either until at least 4000 rpm, and that's where a truck needs it.
well if you see several post above I have already bought the engine/trans for my project. the 5.3 vortec has 45 more hp than the tuned port and only has 5 ft pounds less torque 340 vs 335.
all with less displacement. I have a LT1 in a 93 vette but have never owned a tuned port. they are good motors. I like the new technology since I work with it daily. they are easier to tune. this truck will be a cruiser and not a hauler.
