Whats the deal with 340s?

The 340 is just a perfect combination and especially the early ones with the good cams and big valve heads. I have some avid Chevy racers as customers. They love to build "6 rod motors". I laugh and let them know that All Mopar small blocks are 6" rod motors. (in fact ours are 6 1/8" rods, copied by GM for their LS engines) How about forged cranks, shaft rockers, factory dual point distributors and the like. Mopar engineers designed the 340 to be a performer and it was a force to be reckoned with! No converted 2 barrel small blocks here!


Well no, they are NOT 6 1/4 inch rods in a small block MoPar.

They are 6.123, which is a skosh under six and an eighth.

What's and 1/8 of an inch among friends?
