How much so?
With the increased block width you get increased bore, middle motor mounts and change in bell housing bolt pattern too, correct? | | |

The 194,230 and 250 is both shorter lengthwise and heightwise while being about 24% less weight. The length is approx. 3" shorter. The 292 engine is approximately the same heigth as the old 235-261 family of engines due to it's longer stroke but the same length as the 194-250's.
Hope that makes some semse to you. | | |
