I was told that the cylinder walls would need to be honed and that it is a poor mans stroker kit. I could be a 4.2 and a 4.0 for $75. I would put the 4.2 crank and rods in the 4.0 block. What does everyone think? Cylinder walls "honed"? Not bored? Does this kit include pistons, or is it just a crank shaft? If you just put a 4.2L crank and rods into a 4.0L block, because of the difference in deck height you will have very high compression. To correct for that, IIRC, you will need special pistons. I think you would be better served to rebuild your engine as a 4.0L and, if you want a bit more power, just go for a bigger cam. Link to comment Share on other sites More sharing options...

What does everyone think? That information is just not helpful. You don’t know what, pistons, con rods, crank or bearings come with it if any. You have no way of calculating compression, fuel needs, quench or any other useful metric. I agree with the other suggestions here. Just rebuild it as a 4.0 Link to comment Share on other sites More sharing options...
