I have used the Predator 212 on an Ariens 24 inch , and it works flawlessly …. great performance.

The 420 would be major over kill but a fun project and an even more fun blower! As mentioned the 212 would work just fine.

I dunno. The 11 hp tecumseh on my 24" ariens is definitely satisfying and spends most of its snowblowing hours in the 2400 rpm range. Yet there are times when it's maxed-out and I wish for more.
I think I'm an old power hungry muscle head; I'd never be happy with 'it's good enough'.

I would go with the 212 unless you are Tim the tool man Taylor...then I would go with a OHV 12 hp Tec or a 420 or 414 cc Chondra....

i would agree with the others that both the engines you are considering are overkill. i guess it really comes down to price difference. if there isn't really much off a difference in price between the 301 and 420 you might be better off with the 420 but if the 301 is a cheaper might be better off with it. my 26" snowblower has a 250cc engine on it and it seems pretty happy.

Also, consider how much custom work you want to do. The 212 may be a more or less drop in replacement for your Tec 7hp. Things to consider, crankshaft height, diameter and length, base plate hole pattern, will a new belt cover be necessary, will the chute control have to be relocated. I have a 212 on a 24" 1986 Toro that throws snow 40 feet. The 212 just bolted on the Toro 524 (38040), same base hole pattern, same crank height, used the original belt cover, no modification to the chute control was necessary, the 212 only needed a shaft adapter to take the 3/4" crankshaft to 1" for the original crank pulley.

.
The 212 combined with an impeller kit does really well. IMO there is no need to go bigger. It never bogs. And if you go this route I suggest the hemi #30363 version for it runs better and seems to be of better quality than the non-hemi I have in a mini bike. They are from two different manufacturers.
