stock 20 on stock 22 block is 30 or more HP, put bigger valves, ie 22R valves in the 20R head and a nice stage 3-5 LCengineering cam and some dual valvesprings a 38weber, or maybe sidedraft carbs and you can get 200HP
Where do you come up with all this nonsense?
You are NOT going to gain 30hp by putting a stock 20r head on a stock 22r block. A 30hp gain on a 22r is huge. Also to get 200hp from a 22r will require a LOT more than the few simple mods you mentioned. Apparently you've never been around a 200hp 4cyl. I've helped a buddy who races a 4cyl circle track car for years. It's not easy to get that kind of power out of any 4cyl without some type of forced induction. Also a 200hp 4cyl runs so eratic at lower rpms that it would not be practical in a trail rig.
For most practical purposes a 20r heap swap is not worth the trouble. Don't believe all the hype.
