The year of the square style is 73 threw 86 with the main changes being the front clip. This is a 77 the motor I built 10 or so years ago it is a 468 witch is a 454 punched then lots of head work and a monster cam and super stiff valve springs to deal with the big lob of the cam it is sitting around 500 + hp

was that truck originally a big block truck? what trans are you running behind that monster?

as for the square bodies, they ran from 73-87 in the trucks and up until 91 with the suburbans and blazers. I was just guessing you were 73-80 based on the front marker light in the fender, 81-87 used a square style lamp instead of the rounded one. My 'stepside' is a '75.

I don't know if Glen is on the forums anymore, "Iron-man," he had a squarebody also, I think...

You beat me to it Rod. you also forgot to mention that the crew cab trucks were also the square style until 91 too. They changed the front grill section to allow for the mini quad headlights in the 88- 91 style vehicles. The front clip was different from 81 through the 87 or 91 style.

P.S. some chevy truck trivia. The 88 round truck style was designated by chevy as the "CK" stlye. What was the previous years called?
