when putting a LS cran into a Gsr block which crank bearings are used?
Ls or Gsr??
do any modifications have to be done to the head or can i just slap it on ??

 

anyone???

 

all b series mains are the same. match the rods and crank with the rod bearings (ls rod bearings in your case)

 

thanx

 

You need to do some measuring to do this right.

you need to measure all the rod big-ends, all the rod journals, the block main tunnels and the main journals.

The hack way to do it is to just order some random bearings then hope it's right, and use some plastigauge. I prefer to measure, order, measure again (with plastigauge) and not have to deal with having the wrong bearings. Honda bearings are expensive. Generics aren't available in all the sizes that Honda offers, but are way cheaper. good luck.
