Hi everyone thanks for being there for all of us who have ???s I'm sure glad I found this site. How do I tell what motor my 68 firebird came with? My friends parents owned this since new but his brother Blew the motor back in the 70's, and replaced it with a 326 tempest, the block is long gone, but the car has only 26000 original miles on it.I know it was a 350 because of the hood emblem, and this car has never been molested, it's all original, 4 speed, except the motor. Is PHS documentation the best way? How do I tell if it's a WK or what not? I hope I'm not beating a dead horse, but I did look through many pages and found nothing on this topic. Thanks for the help.....Joedirt
