Post your favorite Mopar Myth.

The 396 is a big block but wasn't it done off what was the GM 400 block, just bored differently? INSTEAD of the full 400 CID it came out to 396, due to the stroke as well? I thought the 396 came out AFTER the 400 GM.....And that's why it was known as a "Big Block" Chevy. I could be wrong tho!

No, the 396 and 400 Chevy are different blocks all together.

The 396 is the "smallest" of the big block Chevy.

The 400 was a small block 350 bored out to 400. It was known for thin cylinder walls and wasn't good for durability.

The 409's weren't durability engines. The piston skirts were too short and they had a problem with "piston ****" and excessive bore wear. Hard to get them over 100,000 miles. When they ran, they ran good, but not good for the long haul.
