Main cap bolts
 

I have a Mildly built Lt1 with around 430 FWHP. I have had to pull the engine back out of the car with 3800 miles due to cam bearing probs. But another prob is main caps walking. I used ARP on the mains, but ARP did not offer a bolt set to allow the factory windage tray to be used, so I used the stock bolts in those three places. There is evidence of main cap movement that is worse on those two caps. Detonation is not doing it, plugs were perfect(no specks) rod bearings ok. What do you do to get good bolts in those places and still use the tray? Has to be a solution guys, I need to know.

Thanks,
David

Go about 3/4 of the way down the page. I think these should work.
