I recently purchased a 62 Chrysler Imperial Crown coupe. The owner told me it was the original 413 engine. I am by no means an expert, but the engine has blue paint and what looks to me like a mid 70's air cleaner. I understand Chrysler used the 413 in trucks and motor homes thru the 70's. My...
The 413 was the largest displacement Chrysler engine until 1966 when the 426 & 440 took that spot. The 413 was used in heavy trucks & RVs through the 1970's. They saw industrial & marine applications as well.
The sole engine was the full police-only 413, hooked up to a standard manual floor-shifted 3 speed; there was an optional automatic. 1964 was the Enforcer’s last gasp, and it was dropped at the end of the model season.

NEW! 413 dyno tests conducted at Chrysler in 1959 This work resulted in the 1962 introduction of the Max Wedge 413, which came equipped with not only a cross-ram setup (this time a short one with the carburetors mounted conventionally between the valve covers), but also a pair of huge, upswept cast iron exhaust manifolds.
I would guess not. The Imperial 413 was the 340 horse version, the same rating as the 413 in ordinary Chryslers. There were 360 and 390 horsepower versions used in the 300.
The 413 was the king of the hill until the 426 wedge and the Hemi came out a few years later. But as mentioned above it depends on what they started with and what if anything has been modified over the years.
