Main Bearing Cap Differences

[southside]

Hi All,

I'm struggling to find a definitive answer on the net and all the workshop manuals for each Series use the same generic picture but can some one identify which main bearing caps are the early type and which are the later type?

Any info appreciated

The top picture shows the later style of main bearing cap, for B and J series motors.
The bottom picture shows the early (ribbed) style of main bearing cap, for all the 132 motors.

I was only made aware of the difference a couple of weekends ago.

From what I understand of it, the two different caps are interchangeable, provided you also use the correct bolts (ie the two cap types each have unique bolts).

Cheers,

Correct Harv I have x2 b blocks. One with each type. And one J block that has the top type fitted. From speaking to a few people and looking at a few different setups I'm pretty certain the top ones are the later model.
