1964 was the first year Dodge put big-blocks in the pickup trucks with the 426 cube motor in 1/2 and 3/4 tons - 365 max. horse and 465 max. torque.
Those figures were measured different and reflect gross, not net.1967 was the first year the 383 got used in the trucks with 258 horse and 323 pound-feet of max torque. 1972 was the first year for the 360s and 400s in trucks. 1974 was the first year for the 440 in trucks. 1978 was the first an only year when the Misubishi six-cylinder diesel was offered in 1/2 ton and 3/4 ton trucks. 1979 - no big blocks in trucks - 360 largest engine offered. Chrysler cars had a 392 hemi in 1957 with fuel-injection in 1958. 383 and 413 was offered in 1959. 440 in 1966. A friend of mine collects big-block Mopars and gets many for free from junked motorhomes. Around here - big motorhomes die early since snow sits on them in the winter and ruins them. He finds a lot of 440s in years newer what was in cars and trucks - I suppose motorthome builders used left-over inventory.
