What would be the advantage of using a Predator 420 engine rather than a Predator 212? The gocart I am building is a 2 seater to be used by the grandkids in the field.

420 has more power and torque out of the box. Would be good for a large go kart or mini buggy. If you're really serious about going fast, you can certainly modify the 212 to put out comparable power to a stock 420 all the while revving way higher (way more top speed) for a similar price point.
- Stock 420cc (13HP/18FT-LBS) w/ 40 series TAV = $750
- Stage 2 212cc (15HP/roughly 15FT-LBS) w/ Juggernaut 30 series TAV = $740
But since you mentioned it's for your grandkids I doubt you want to go crazy with top speed.

can the 420 be similarly modded, though?

IMHO there is no advantage using a 420 for your application. Do you want your grandkids flipping the kart or cruising at 40 plus MPH on a gokart?? The electric start is a nice feature but that can be easily added to a 212. One more thing to consider is if this will be used as a yard kart you probably will want/need suspension unless they are riding on very smooth ground. Any anomalies in the yard will beat the kids and the kart up badly. Good luck on the kart, let us know how it comes out.

Of course, but modding a big block gets expensive real quick. For the price of a stock big block and applicable transmission, you could have a small block that outperforms it. Similar power/torque but way more RPM (and less weight). More RPM means more top speed OR the ability to gear even lower than usual for more torque while still retaining the same speed. The latter is a huge benefit off road.
