What's a 413 or 513 engine?

Question

What do the numbers tell you about the engine in the car?

Answer 1

horsepower

Answer 2

Back in the day when metric wasn't the standard in engineering, cubic inches were the measurement.  Thus, a 413 and a 513 is the size of the engine, however, I am fairly confident to say that there was no such size as a 413 in MOPAR, but there was a 418 and a 318.

Answer 3

yes back in the early 60's mopar had a 413 cu. in. engine

Answer 4

the 413 was one of Chrysler's big block engines one of the older ones,they was good though,all the numbers do is give you the cubic inches,like newer model cars say 1.6 liters,this is the new way of reading cubic inches,the metric way ,back in the old days they still used number like 413 and 440 to describe an engine and its size,that's the only difference in the old ones and the new way,good luck.

Answer 5

That tells you the displacement in cubic inches

Answer 6

413 or 513 cubic inches displacement. 513 is really really big, some of the old caddy v8's were 500 ci.
