no
Not without major modifications.
its likely a 318, maybe a 360. neither of the two you mentioned.
the 440 has much more power but the 383 is louder the 440 is harder to find
383 (cubic inches) = 6 276.24551 cc
slant 6, 318, 340, 360, 383, 400, 426, 440 some of these engines came in hemi's and magnum's
On the 383 Dodge , # 1 on the distributor cap faces to the front and slightly towards the passenger side
318 =160 hp 360 =180 hp 400 =200 hp 383 =258 hp 440 =235 hp all where found in dodge trucks from 1972 to 1980
WELL FIRST OF ALL THE 318 AND THE 360 USE THE SAME ENGINE BLOCK (LA) JUST DIFFERENT HEADS AND BORE SIZE, AS FOR THE 383 ITS PART OF THE DODGE BIG BLOCK FAMILY (RB) AND THAT CAN BE DONE BUT SUSPENSION MAY NEED TO BE DONE DUE TO THE EXTRA WEIGHT BUT IM PRETTY SURE IT CAN BE MOUNTED IN WITH THE RIGHT MOUNTS AND IT MAY DEPEND ON WHAT AUTOMOBILE ITS IN SO GOOD LUCK GO MOPAR
18
yes.
If you have a 361 the 383 heads will work, but they won't work on a 318.
Since a 1998 truck was not available with a 383 you would have modify a trans that bolts up to a 383 to fit the truck.
