XR275 cam in LS2, what else in the valvetrain needs an upgrade? Hi, Ive been having trouble finding out a few things:
I have a std LS2 motor in a SWB landcruiser and am thinking of swapping in a mild cam.
The cams I am thinking of are Comp cams:
XR273, 220/224 .530/.534 on a 112 LSA
or, XR 275, 222/224 .566/.568 on a 112 LSA with more agressive ramp rate.
will I need to upgrade the valve springs and or pushrods with either of these?
I have found a 2nd hand XR275 for sale that comes with:
THUNDER RACING 7400-080 HARDENED PUSHRODS AND VALVE SPRINGS TO SUIT.
This was out of an LS1 motor. will all these components fit an LS2 motor?
basically what im asking is if I buy this stuff will it bolt straight in? are the pushrods the right length and will the valve springs work with my stock retainers?
heres the link:
