Caterpillar offered a series of medium duty diesel v8 engines in the mid 60's. They were the 3000 series. (later 3208) Ford was the first to use these diesel engines (exclusively for a year or more) and were called the 1100 series in the Ford trucks. Some people said that they were a modification of the 534 block, but this was not true . They were designed and built by Caterpillar.They had no sleeves but were of parent bore like the 534 and overall were about the same size as the 534. The earlier models were naturally aspirated, ratings were in the 225 horsepower range.
Later Caterpillar made turbocharged marine versions of these engines with ratings close to 500 horsepower.
