Thread: LS1 bearings.. help and inputs..

well i am down to needing the bearings for the bottom end.. i was at Smith auto talkin to keith about what to run and he thought i should get others input being that he doesnt do tons of newer stuff..
so i been lookin on LS1tech and seein what others are running..

it looks like most are running clevite but keith said some good things about ACL witch he has only seen in a 1000 hp 4g63 4banger for the salt flats...

also what would be the right clearance to run for a turbo alum block??

all input is welcome hoping some of it is from the right people

thanks guys..

I dont know jack diddley shit but I would run the ACL bearings. I am gonna try them out when ever I get to needing bearings. Never used them myself so personal experience but I have only heard god things about them.

same here from a whole 2 people now lol but i hear they are harder then the clevites and last a long time

We run clevite h bearings,we ran the coated h bearings in sean cagles turbo motor,and all our own stuff uses clevittes

On a boosted or nitrous motor u want the bearing to be a cushion just a fyi.

oh ok...so softer is better....

it saves rods and cranks

bearing wears not the part makes sense..

its the shock of the instant force on the piston,it hammers the rod,thats why like really big big nitrous or blower motors run aluminum rods to cushion the crank so it doesnt break the crank

turbo is a lil more gentle though isnt it.. while it builds boost..
