Main cap girdles re-discussed

gagembassett said
I was just rereading a thread I commented on a long while ago about main cap girdles and the ending consensus was a no..... HOWEVER I did read it and it seemed to me that everyone was only implying it to 2 bolt main girdles on an LA factory block. Now I do understand that some people still run 4 bolt caps and leave the outer bolts unused just to help transfer the stress across a more broad surface area. So my question is what does everyone think about running 4 bolt caps for that and adding a girdle on top? Yay? Nay? Why?

I run a girdle on my 340 block and I'm putting out about 625 HP on alcohol. The main caps had to be machined down where the stud nuts and washers set, this way I didn't have to shim to get the girdle to fit evenly across all the main caps. Been running it hard for 6 seasons and the main bearing look like new. Running 6.50 sec. to 6.67's at 101 - 102 mph in the 1/8th depending on the air, tune and traction.
