I'm going to relocate the water pump using pre66Dave's kit. I'm looking to see if it's a car or truck engine. With the A in the serial # should be car ?? I also have another 235 engine with the codes Block # 3764476 Date D279 and a serial # F504B Would this be a truck engine ?? Is the any other way to identify car from truck ?? The water pump kit suggest a truck harmonic dampner. Thanks for the help.
