They would be great in a work truck because they build great torque off idle. My 90 was rated at only 245 hp but had 380 ft-lbs of torque. My 95 LT1 was rated at 275 hp & 340 ft-lbs. The 96 got a 10 hp boost due to the dual cats.

The smart TPI guys put on a Holley short runner intake and add an LT4 hot cam setup. It really wakes the engine up.

Add vortec style heads and you get the best of the LT1 technology with the reliability of the gen-1 ignition & accessories.

All the technology but one, reverse flow cooling, allows the LT1/4 to run a higher static compression ratio than any Gen1 chould on pump gas.

Does holley make a short runner TPI intake for vortec heads? And does the holley intake have EGR provisions making it street legal for 3rd gen camaros & 4th gen corvettes?
