20r can't pull us up hill. Any tricks for a little more power?

1980 20r . in the tiny rbr 17ft one.  Almost hit 35 crossing the blue Ridge Parkway. In 2nd gear.  It's not a happy camper.  

   What's the easiest power option?  Sup up engine? Swap engine? Swap house out for a Tacoma or somthing?  What fits?  

  We are in the market for a bigger camper. But the market is not great this year.

You can de-smog, add a Weber 32/36 that’s about it. Your 20R only has 97 hp to work with.

I’ve done all that, but it is what it is. Blue Ridge Parkway is an extreme example. There are many new 4 cylinder cars that would have that same problem on the parkway.

What transmission do you have?

Your driving an overloaded, under powered, 40 year old pickup. If your REALLY giving thought to newer, bigger rig, just drive it. HP cost $$ how fast is your wallet?

Upgrade steps

Stage 1. Weber carb  and cam...105HP. A Weber 32/36 will give you a small increase in hp and MPG. A 38/38 will you more HP and less MPG. Both bolt on with an adapter. A camshaft with a degree rating of around 270 is OK. To much more than that is more HP at full throttle and a bunch less grunt at lower rpms. Mountain pass speed 38 mph

Stage 2. A 22r with same cam and carb. Add a header and good exhaust. 120hp. Mountain pass speed 42.

Stage 3. this where the budget gets really stupid. Stage 2 engine, 5 speed transmission and a 4.56 rear axle ratio. Mountain pass speed 50 mph in 3rd gear.

Stage 4. Insanity. Toyota 3RZ, 150 hp needs matching 5 sp transmission This is 1990's V-6 power.

Stage 5. Criminally insane. A 350 cid SBC with 4 sp automatic. Mountain pass speed... speed limit...https://www.advanceadapters.com/tech-vault/1-engine-swap-info-toyota-trucks/

P.S. Blue Ridge Parkway drive out here is considered foothills. Try a 10000 ft pass just for fun.

I have a 1978 sunrader what I did was redone head put a weber38 carb and a header and 2 inch exhaust, it has more power and is noticeable and I can pick up speed going up hill,but is still not a whole bunch of power ,it is not cheap  to do.

Great reply. Was hoping a Webber would be the answer .  or fit it to a Tacoma 4x4.  Still throwing money at it. But not that much. It will never fit 2 humans and 2 cats. Or carry a motorcycle on its 5 lug axle.   Broken down again today. Wiper went out. And house dc power is lost to.    Was a long dark rainy drive with 1 headlight and no wiper. Up a back mountain rd.   No rain ex around.   Up date. Wiper fixed in 6 seconds. I expected much worse.
