Actually, 442's in the beginning years being 66 and 67 also had the 400 cube motor. There were some 65's, and I believe those also had the 400 cube motor too. If I am not mistaken ( and I could be, so please bear with me) Olds changed the motor to a 455 starting midway in 68 due to new smog regulations passed courtesy of the EPA. The 455's ran cooler and produced less emissions, even for a big block.

I like the 400 motors, they have tons of torque and HP for what they were in stock form. Also, early 442's that have their original 400 cube motors are becoming more rare, heck even finding a 400 block and heads is very tough..

just my 2 cents worth.. hope it helps..
