If you had a spare ZL-1 block sitting around... that would be one way to drop the weight on the blower.... Says at 800 pounds right now with a regular block.
Or you could add a 512 block instead and some Yenko badges for a special touch!
How about an LT-1 swap? Need a seat tranny, mowing deck and a lawn mowing/leaf blowing attachment too so you can use it all year.
Snow blowing for distance hmmmm.... More HP=longer and higher snow distance.....You could almost make it snow on your next door neighbor....
Heck Uncap it and run open headers just for effect Snow blower racing cannot be far behind.
