That is totally true!! For instance,one motor had 3 different options.Like the 396,in 1969,It came with 325 hp,,or you could order 350 hp,,or you could order the L-78 option which came with 375HP.Im sure the people on the assembly line use to slip a "Hot" cam in the slower cars every now and then.Also there is a famous story about a GTO back in 1965.They tested a 1965 GTO against a 1965 Ferrari-GTO.(thats where Pontiac got the name) Anyway the test was pretty good and the performance #'s were pretty close.It wasnt till years later(The truth actually came out in the late 80's,,Jim Wagner told the truth) when Jim Wagner fessed up about the test.The night before the test,at the dealer,they took out the 389 Tri-Power (thats what motor they came with) and slipped in a 421 Super Duty.The motor that came in super stocker Catilinas,it had more HP and torque!!But to look at them you couldnt tell the difference.And Im sure stuff like this happened all the time in the 50's,60's,and 70's.Today it would be tougher,but Im sure it still goes on.p5.0ny said:Factory freaks are real. Just not anymore. Back in the muscle car days, lots of substitutions took place when there might have been 6-7 different engine options for a specific vehicle line. It was not uncommon to "upgrade" a car if the required engine didn't meet the car on the assembly and an "upgraded" engine was there. Examples I know of higher horse power ratings than then build sheet called for. 10 vs 12 bolts for Chevys were commonly switched to 12 bolts. With less options, the factory freaks are gone.
