Re: Is it true that .....
I see a lot of fairly knowledgable people looking for 4 bolt mains to build.I have to wonder why since if you are building for major power,you are better off to start with a 2 bolt and have it machined for splayed 4 bolt caps.The main reason given for this is that the webs of the 2 bolt are stronger and the splayed caps are even stronger than the factory 4 bolts.If someone were building a serious engine with the cost involved I would think buying the caps and having it machined would be a fairly simple and cheap way to get that strength.Also it seems like most of the aftermarket blocks use splayed 4 bolt mains also.
As to whether the engines are 2 bolt or 4 I have taken a couple of original to the truck apart,One 2 and one 4 that I recall.
