Hello there, I was just wondering what the differences are between the WD and the WD-45...and I was also wondering if the block off of a WD was the same as the block off of a WD-45. THANKS

Josh

WD has 201 cubic inch displacement where the WD45 has 1/2 inch longer stroke giving it 226 cid. The 201 cid engine is easily spotted by the large rectangular plate bolted to the RH side of the block behind the mag/distributor. Late model WD's and all WD45s had curved shift levers and beveled gears, early WD's had straight cut gears (straight gear shift lever) and more tranny noise. WD45s also had an additional clutch plate in the hand clutch and came with the traction booster system. WDs after '51 or so had distributor ignition and all WD45s came with it. WDs typically had 13.6 x 28 rear rubber and the 45s had 14.9 x 28 rubber. WD45 was also available with a 6 cyl Buda diesel engine and later models had an improved 4 bolt wide front end.
