Currently in the process of LS swapping an 05 that once had the I5 in it. From what I've read, the differentials in these were weaker than the ones that later came on the V8s. Anyone know where the stock power limits are for this diff? Would like to try and get away without welding it but if it cant hold 450+ hp then it may be our only option until we do a Ford 8.8 swap. It's an 05 Z71 2WD if that helps at all.
