I'm going to "Sound off" here a bit but first I want to remind everyone of my racing heritage. I've been involved in racing snowmobiles, mud drags and D.I.R.T. Modifieds and now lawn mowers. What I first found ironic in lawn mower racing rules was the "Must start as a certain block" and "All internal modifications are allowed". What? No other racing organization that I know of allows internal modifications without limit yet bases the start off an engine cu in. If you are going to have a cubic inch or cc limit it must remain as a complete limit. Let me give a clearer example using a small block chevy. A typical 350 without being resleaved will get to 4.060 maybe 4.090 if the casting is really good. Now a bowtie block 350 will get to 4.215 from its 4.00 stock bore. A small block 400 will get the same. But now you say the small block 400 isn't legal because it started as a 4.125 bore at the factory. Kinda nonsense if you ask me. That's why they use a cube checker to keep everyone under 368. If I want to run a 4.125 piston and 3.44 stroke it is allowed. If I want to run a 3.82 bore and a 4.00 I can. The is no physical size difference between the 44 and the 49 block. It can not be measured externally to separate the two. There is a minor casting difference that allows a trained eye to differentiate the two. This is not a big block. you can't make the Intek 49 as big as you can the 46 Kohlers with any amount of boring. The material isn't there. What I see is the pure hatred of the intek by people who shrug their shoulders at 60+ cube Kohlers.
