What mains to use

[unionmax481]

Building my motor trying to decide if I should just run stock mains, billet mains or a girdle looking to have the truck around 1000hp but won't be at that level all the time probably DD around 700 for the most part just wondering what everybody else thought are on this see what other people are running

I did billet mains, SoCal's girdle and stud kit. I'm at the power level you stated.

You could do either and be fine.

I guess what trying to say can you girdle the stock mains or just put billet w/o a girdle how do you really gain how much could a stock main hold with studs

I run stock mains with studs. I have 60,000 miles on my build. I'm about 900hp now

Stock mains on mine

Stock studded mains in mine

You can do one without the other, the oil pump needs to be installed before girdle goes on though, tight fit.

I'm doing billet mains and a girdle.

No need for a girdle at that power level IMO. Only reason all those Cummins guys do it, is because there isn't anything holding the caps from the side like the dmax block.

I agree. I am running them for the added protection if I ever chose to go big on power.

Larry from Danville had advised not to run those billet mains unless the correct machine work was done with them.

When studding your mains stock or billet it always good to have them line honed (line bored)

It's more a requirement. Not doing so can f a crank up in a hurry

If you have the $$$ for a 1,000hp motor, the girdle is a small price to pay compared to just the gaskets, seals, fluids, and machine work if something goes wrong, nevermind any actual damage that might happen.

I was at 730+ for a year with stock mains stock bolts. Another year at 850 with stock main caps and stock bolts. (Original stock bolts) now putting in studs with stock caps

Just gonna refresh the engine. Putting in all new bearings and seals. Main studs, balancer etc. looking for more power this season too. Btw when i had stock bolts, they were reused 100,000 mile stock bolts lol
