So - I know I want/need a new cam and carb. Seems both of these are worn out - original, nearly 300,000 mile old equipment. Exactly what kind of cam by what manufacturer should I get for my very weighed-down camper truck? I know that I'd like a bit better performance, but I want to get as many miles as I can out of this really good 92,000 mile old engine rebuild. Don't wanna put in anything that would risk burning anything up, particularly with the big load I'm hauling. As to the carb, which Weber would be best for this application?

Thanks again, - Charlie

Whoops - did I forget to say that this on an '82 22R? Geez.

i would vote comp or engnbldr 260ish on the cam and a 32/36 weber carb

why switch to a weber? the stock aisin carb is very reliable. lots of praises over the weber are usually followed with admission of jetting issues that haven't been resolved.

unless you are getting rid of your emissions equipment or building a powerhouse of a motor, i see no reason to change.

i agree with al. just rebuild your stock aisin carb, i rebuilt mine, took a few hours and it runs great now.

x3 with al.
The aisin carb is a great carb.
again, the toyota trucks are some of the few trucks where OEM is better than aftermarket 99% of the time.

Weber 32/36 and Engnbldr's 268 cam. I've been runnin this combo for over 3yrs with ZERO problems, and that little 275K mile 22R pulls like a team of cracked out mules.

Make sure you are getting a "genuine" Weber and not a cheaper priced knock-off. You get what you pay for.

I got mine at webercarbsdirect.com, cheapest out there for the 32/36 and it's a real weber.

I have the same combo 32/36 / EB268 but on mine power doesnt kick in until maybe 2,500 RPM but when it does it pulls hard (for a 4cyl) even on the 4:10's and 31's. Enough power to chrip the tires on a 1st gear clutch dump and 2nd gear shift.

If I were to do it again though, I think I would go with the weber 38 and 261 cam. For the ultimate low end. Especially since my block was shaved down and I am bored 30 over with a new stock EB head. SO my cam timing is probably about 2 degrees off (retarded i think) from where it should be affecting my bottom end some.

I have this combo and it works great. My block is stock, but the head has over sized valves from engnbldr and a header and exhaust work. Recently, I had to get a new head after some spark plugs were cross threaded. That's when I did the over sized valves and added an offenhauser intake to the mix too. When the truck was put back together, a stock cam went in, instead of the engnbldr. I drove it around for a few weeks like this before the engnbldr cam went back in. Its not night and day, but I can feel the gain in power on the low end. It also idles better, ironically.

To the OP, email Ted and tell him what you have and what you want. It sounds like an RV cam might be the setup for you? On the carb, here's my opinion. People that hate webers or hate the stock carb had a bad experience with them. I think a stock carb, when rebuilt CORRECTLY, performs well. A weber carb, installed correctly, will perform even better...if its installed correctly. Key word..correctly.

The Weber 38 works great if you have some engine modifications, but its not worth it on a stock engine. The 32/36 is probably the Weber for your setup.

truckman1966

when you buy a "real" weber, they give you instructions on how to tune it, troubleshoot, and parts list to modify it. grab a weber. the throttle shaft wont be loose and causing a huge vac leak like your aisin.

Hey thanks everyone for all the great info.
A little clarification: My setup is stock, save for Downey header that's treated me right for eight years. Basically, I think the Aisin carb is shot beyond redemption. If I rebuild it, it'd be the third time. The secondary coughs like bear when I step on it, and kinda mutters the rest of the time. So what IS the bore on the stock Aisin? With a new Weber, I don't think I'd wanna go much bigger. After all, this is a camper rig. I just need to be able to go down the road easily and cheaply, if yuh know what I mean.

the weber 32/36 CFM rating is actually I believe just slightly lower than factory. Not enough to matter so it is pretty much the same.

Both my 81 and 87 carbed engines don't have this problem.. sooo... id like to hear your sources?

xxxtreme22r

yeah my aisin never had that kinda problem on my 87 either, just the stupid choke.

Nimyad

ya never had that problem on my aisin either, the choke did rev so high it was like a had cruise control though lol, used a whole can of carb cleaner before it stopped.

xxxtreme22r

lol at least yours worked lmao. I got so sick of fooling with it and trying to find a non $80 one that might not even been the correct one and bought the weber.

Nimyad

you know if it was just the choke you can stop it from opening and just not have a choke so you don't have to mess with it.

xxxtreme22r

yeah did that for a while but no choke in PA or WA in the winter don't work out so well.

Nimyad

ya, just have to sit in it as it warms up lol. that's why there's warm drinks

I changed to the Weber 32/36 after the stock rebuild left me very unimpressed. Now my 83 runs great! Best 300 I spent...

Champ

I got my weber 32/36 in the mail today. Hopefully when i get off work at 6am i will have the energy to put it on if not it will be sunday. I think i am gonna be alot happier with it once installed.
