Whizzer - Like they said, it's not a bolt-in, but shouldn't be that tough. The block is narrower and requires special mounts. I think Landgon's Stovebolt has them. Also, be sure to run the numbers. The early Nova's had a 194 as an option to the 4 banger. The 194, 230 and 250 share the same block. Inliners.org probably has more info, and does have a good number chart.
