I did some searching and i read that you have to take to bolts to a machine shop to get them resised, is this true?, or can I just slide then in is there anything else I should do or get maybe some acl bearings, this all gonna be on the stock rods, and oh yea, this for my b18b1 block

 

bump

 

You are correct.Take them to a machine shop and have them installed and resized.

 

okay y do they need to be resized, the ones I bought are the 8mm ones and according to whereI bought them from they are meant 4 an LS block

 

well I did a lil more search from what i found out is that the ends of the bolt have to be resized in order to have prpper bearing crush, can some explain this to me,

 

bump!

 

yes the right way to do it is to have the machine shop press them in and then they will resize the big end of the rod..

On the other hand i have friends that have installed the bolts themselves with out resizeing and have 0 problems with their builds...

Going with the machine shop route is the way i would go for sure though..

 

so ur frnds havent had any problems, see this is only for now i'm gonna re-do the block later for boost, all I want is to rev to 8k w/no problems while I'm all motor cuz my 404s r going in my ls head.

 

Changing the bolts slightly distorts the rod bearing bore.Resizing the rod after installing the bolts corrects this distortion.Some times you get away without doing it.I would keep the stock bolts rather than changing the bolt and not resizing the bores.

 

well would my ls block handle 8k then w/ out the arp bolts

well Im thinking will resizing the connecting rod bearing cap wil that be enough or do i need to do the whole rod, I'm not trying to half *** **** , I'm just asking if that will suffice, If not will my stock ls block handle lets say like 4 runs of 8k,

 

OK,you might want to take a minute to think about what you want to do.The stock ls really doesn't have a high enough compression ratio to take advantage of the 404's.If your plan is to boost than just wait and go with some aftermarket rods and forged pistons.If your bent on running the cams then bolt them in and do your 4 passes.LS's are cheap enough that if it blows just get another one and boost it.Lots of people have made 300hp and turned 8k with a stock bottom end.You just can't do it for very long.

 

Ok, this is what resizing the big bore is. The rod cap is cut shorter, put back onto the rod, and the large bore end is then bored back out to the stock spec. It'll cost around $10-20 per rod.
