The only difference I can see, going by part#s, is a different cam. The compression is rated at 8to1, on the 290, and 8.5to 1, on the 260. Like I said, looking at the part #'s the only difference is the cams, but there has got to someting more. I would buy the 260, and change the cam. CarCraft had a great series of stories on building one of the 260hp crate engines. With very little work it made 300hp, 400+ with a head swap.
