Question for those with a Big Bore block in the garage

[05stroker]

Can anyone give me a rough measurement of how wide the main cap is and the distance from center of the left bolt hole to the center of the right hole?


I have a block coming, but want to get a head start on a project I am working on.

roughly 3 3/4"

Is that the bolt hole centers?

No just main caps for now...

Thanks, can you get the actual dimensions of the mains?

Have you considered calling JPC or RGR? They are the ones that used to offer the 4 bolt, billet main caps for the big bore iirc

 

[deebo05]

I'm going to call today. I seem to remember someone trying get them and being told that they don't offer them anymore. I will find out today for sure though.
