cool page. found this stuff..
V8 - 305 / 5.OL V8 - 350 / 5.7L V8 - 383 / 6.4L V8 - 454 / 7.4L Std. Rotation 1-8-4-3-6-5-7-2 Reverse Rotation 1-2-7-5-6-3-4-8
If you latch on to a early 366 or 427 tall deck truck motor you may find that it used a gear drive for the camshaft. Chevy and GMC used just two gears to drive the cam which was a "reverse" rotation grind. You can switch these early tall deck motors over to a different "normal rotation" chain driven cam, but make sure you also change the distributor drive gear to a "normal" rotation gear.
I have never heard of a reverse rotation chevy until now.
learning everyday!
