i bought this pump from a junk yard in cali. he said it was from a 5 speed 97 model truck. well it shows up and has a tps on the linkage so i call bs. any one have a idea what i have. i have had the timing at 5.4, 5.7, 5.9 and 6.1 mm of lift. i have it at 5.9 now and it wraps like a small block chevy. it wrapped well at 6.1 but it did sound high so i backed it off to try to save the headgasket. it is still cold here and i don't want to ride the harley yet. here are the pump #s 0 402 736 912
