Pat and Richard -

Sometime in the wee hours of this morning (what, exactly, is it that makes some hours "wee"?) I dug out the big pile of Chrysler stuff that fills up a whole drawer in my dresser.

I was curious about that "413 hemi" we hear tell of.

I wasn't in a position to say "there ain't no such animal" because there was, after all, a "Slant Six hemi" produced.

I didn't find any mention at all of a 413 produced with hemispherical heads.

It may be that somebody put some 426 hemi heads on a 413 block, I dunno, But why would a person do that?

The 413 RB (wedge) first showed up on the '59 Chrysler. It was then used in the '61 Plymouth.

The 413's finest hour came in 1962 when a version was sold as a drag race only option. Those were the ones with that hairy-looking big wide cross-ram dual quad intake manifold. The engine was available with either 11:1 or 13:5:1 forged pistons, a high lift long duration cam, larger port heads and high-flow upswept exhausts.

It called the "Max Wedge 413' and made 410-420 horsepower. This (413) version was dropped in favor of the 426 in 1963.

i'm not agreeing or disagreeing with anybody, Pat, but I can only say that in my (mostly wasted) 76 years I never heard anybody refer to a 413 hemi.
