After two water pumps and a distributor thats all the major maint. I've done of course I do the high way patrol sch, changing all fluids at every 3/36 and using AMSOIL sense 96. spent $22,000 sense then on maint. tires,oil, rotation, etc.
LT1, second gen chevy motor, reverse cooled, 10.5-1 compression ratio using 87 octane fuel. 18/25 MPG
Transmission, shift points is the magor problem, flushing 20 quarts every 3/36 has saved me
