Starting up my 1990 cummins in -6 degree Farenheit weather to go feed the cows, it has the 5 speed, bd 40 horse injectors, hx 35/40 hybrid, 4 inch full exhaust strait pipe, dennyt stage 2 fuel pin, 3200 RPM spring, coolertubz crossover and the pump turned up. Sat all night with no block heater and one cycle of the grid heater
Them ol' first gens will start when nothing else in this world will! Very good and tough motors
