I reacently got a 250 xflow and C-4 from Xflow_Fairlane.Great motor.(Thanks Nick)From what I can tell it is a july 1985 XF? The block reads JG23FA 20290C.I know the horse power changes with everything that is done' But if possible I would like to know what stock HP is.(I don't know how to convert imformation). And is there a site that has this imformation listed.Maybe a conversion chart.It's in my '62 RANCHERO. Thanks Ken N.Yes I have spring Fever.GOT TO TRY IT ON THE DRAG STRIP.
