![]() The 302HO does not have this problem, nor does the 351W. The Lopo Windsor, when it wore rod bearings, would wear the first couple cylinders. Some may disagree, but I believe GM's own research agrees with this, and when the LSx engines were developed, they adopted the same cylinder firing order. The reason for the change was that, from my research, it was shown to provide much more even loading of the crankshaft, reducing bearing wear. ![]() This has been Ford's "defacto" firing order since on all V8 engines. The traditional V8 firing order for both the SBC and SBF (things are a bit more convoluted with Dodge, so I'll omit them for now) was:Īs far as Ford goes, the change in firing order on the Windsor engine to the HO/351 version was done when they increased the power output. ![]() I've been thinking (a dangerous thing at times).
