I have heard that the rod journal on a WD is smaller than a WD45. The WD rod Is shorter also It has a smaller stroke. Is this information Correct?

Thanks,

Wc/Wd/Wd45 use the same con rod. journals on crank are the same. compression height in piston is the difference for the 1/2" stroke. wc flat tops with 45 crank boost compression up to 10 to 1. good luck

wd,wc and 45 rods are same lengh and journals are same size. 45 crank with wd aluminum flat top pistons will up compression and boost hp.d17 cam will give a little more duration of lift port and polish head and intake will help move more air you can do all this about 500.00

WC/WD has the same size crankshaft journals as a WD45, that's why the 45 crank will drop right in these earlier 201 CID engines giving you another 25 cubic inches. By using the 1/8" overbore sleeve & piston sets you have a total of 240 CID. All of these engines use the same connecting rods, therefore it is imperative to use the 45 "crater style" pistons instead of the flat tops from the 4" stroke engines, as the wrist pins are located in a different place to compensate for the 41/2" stroke 45 crank. The D17 also is a 4 x 41/2 226 CID engine, but uses larger main bearings, so the 17 crank will not fit the W series engines.

The WD has a shorter stroke,4.0 the WD-45 has a stroke of 4.5. As for the connecting rods being shorter I am not sure. I was under the impression that the crank had to be changed. In the archives it has been said the the older 201 WD motor can be upgraded to the Wd-45's 266 displacement by changing the crank shaft. I am not sure that if you have a shorter connecting rod and the same crank shaft, that there would be enough clearance in the cylinder walls to use a shorter rod. It will change the angle the rod obtains in the rotation of the crank and may cause problems. After typeing this out I have douts myself if I am right. I hope others will post and give a different prospective.
