Briggs OHV & Vanguard / Re: 38 vangaurd stock bore size?
« on: September 07, 2016, 11:01:01 am »One block has 38 stamped on top and other doesn't . The 38 block has 1.380 top bearing and the other block has 1.150 top journal bearing, aren't all the 30/35/38 crank journals the same on verticals?
All the engines with date code 1996 and earlier have the smaller crank journal on the flywheel side. They changed to the larger journal cranks with the bearing in the date code 1997 engines and later. They only made 30 and 35ci engines with the small journal that i am aware of. I've never came across a factory 38ci with the small journal. Also, if it has the center breather cover that bolts into the block between the cylinders, its a 35ci or under. The 38ci engines did not have it.
