Just One Idiot is necessary to destroy a Pontiac Engine. Please, no Chevy Guys to work on your Pontiac. Whatever you do ABSOLUTELY NO FORD OR MOPAR MECHANICS! THOSE MOTORS RUN BACKWARDS! How do I know ? Owned several Mopar Cars. Had a 1970 AAR 426 Cuda! Used To be Mustang Dan also. Built many a Ford Motor that actually ran. FOR ONLY RETARDED DUMBIES!
