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.
I understand where you are coming from, Lester, but then how would one word it so that it eliminates the "big block" engines?
And just to throw it out there, our Tecumseh's are 42ci. Always have been.
