Larry, 3.25" crank on a 4" bore. That gives you an excellent bore stroke ratio of 1.72, and the advantage of a wide assortment of pistons to use. Cylinder bore spacing on a V8/V6/I4 is the same, so that opens a lot of possible head options, some are easier to do, with the V8 set looking to be the best choice. Yes, there is machining work to do, but that is not a problem. The 292 block is stronger in the top than a low deck, but that long rod and long stroke doesn't like to stay together too long at 7500 to 8000 rpm. Yes ,I do have a head with lumps, now its time to try something different. Remember this is not a street engine but a full race 3/8 to 5/8 mile dirt and asphalt engine. Flyer, what do you mean by "What Larry Said"? Lets hear somemore one way or the other
