2 questions! Since I’m rebuilding anyways and have a LS crank laying around should I replace the GSR crank for the LS crank and rods? What will this do to my displacement/ compression ratio? I need to order new pistons so should I stay with 9:1?

yes you have to use ls rods with the ls crank. make sure you upgrade the rod bolts. and i believe you have to get the block machined to fit the ls crank because its a longer/bigger/whatever stroke ---

I need to get going on that rear brake swap I don’t mind stopping in, moving an engine or lifting a wrench here or there ain’t to hard. But honestly, it helps me learn before I get to my car 😃 > [@Shrek](#): > > So what would be the benefit of this? more torque? I’m wondering that too. Cause the engine in my car has a longer stroke then the normal engine in the base models, and the SC model. ---

"LS crank give 33 cc more displacement, and usually about 10-30 ft-lbs more torque at the same boost level. Its worth doing. Compression on 9:1 pistons rated for a gsr crank would be a little higher, maybe 0.3~0.5:1 increase. " by Jeff Evans Might as well…right! Still not sure what rods? ---

honestly, you will have traction issues ANYWAY, so unless u are going all out on a drag car, you don’t need to use the LS crank. however, the extra mid-range IS nice, but like I said, I’m not a fan of throwing different cranks into the block…cuz then u gotta check the line-bore, blah blah blah, oil squirters need to be modified (bent/moved) cuz the ls crank will interfere, blah blaah blah IF you choose to go this route, u can either: a) use LS rods w/ the LS crank…just use the rods of the crank you are using and you are good. b) custom +.137 or .0137 can’t remember rods which raises the wrist pin height…makes for a better rod/stroke ratio, letting you “Safely” rev it out higher…real popular w/ the N/A Bseries builders back in the day…unnec. in my opinion for u cuz we’re talking revving it out to over 10K rpm My suggestion is to just use the crank you have, & sell the LS crank to finance some of ur rebuild. edit: my bad, deck heights are diff, but like i said just use the rods of the respective crank and ur good.
