Toyota introduced the 22R in 1981 so it can't be a 1977 22R. I don't know why someone would put a 81-84 22R head on a 20R block other they needed something in a hurry. Or maybe they sold the 20R for beer money and took the 22R head in trade. The 22R head has the swirl chambers for emissions...

Personally having built a mild 22R-E my $0.02 would be not to bother doing anything unless you're going to put a turbo on it. I bumped compression (laser block and 85+ head), did oversized valves in an Engnbldr ported head, a 261C cam. It might have been a little more torque-y off idle but...

https://lcengineering.com/engine-22r-block-head-identification/ Engine – 22R Block/Head Identification LC Engineering's Technical Department has provided some basic information as well as identification information to assist you in modifications to the 20R - 22R - 22RE Toyota 4 Cylinder...

Narrow band analog like you're using is 12.5 KHz channel spacing and eventually 6.25 KHz. Technically the TM-V71 is capable of doing this. It will do as small as 5 KHz steps. Alternatively you can pick 6.25, 8.33 (on AM aircraft band), 12.5, 15, 20, 25, 30, 50 or 100 KHz steps. Most current...

I think there's some miscommunication going on. Their description says "For external box dimensions we use the maximum size of the box with the lid and handles in place. For internal box dimensions, we take the minimum dimensions. All dimensions and weigths are approximate." Which leads me to...

I don't dispute you about hydraulic winches. I agree. But a commercial PTO pump or your HD truck isn't the same thing as the centrifugal vane PS pump on a light duty truck like my Tacoma or a Jeep. It'll work and is probably better than an electric winch but won't be without its own set of...

The V-I curve typical of a solar panel. You have two characteristics, the short circuit current and open circuit voltage. This curve is what the controller will see this as input and match it to the battery on the output. The panel output could be anywhere along this curve depending on...

I think hydraulic winches make a strong case and in all my time I've not yet had a situation requiring winching with my engine not running anyway. The non-running engine argument resonated with the inexperienced me way back. The only argument that I think holds merit is that a regular power...

This was done for the winch I own, an older XD9000. That's a sensible approach.

Agreed completely that the SB350 is a better choice for the task. For a 4 AWG, though, the cable itself is insufficient rather than the connector. At >2 AWG things are different, even more so at 1/0 AWG. At 2 AWG the SB175 is marginal in the application and if you're running 1/0 AWG it's...

I think you've understood but yes, you have a radio with a display and some knobs. You pick a frequency to use the radio and that can be any of the bands it's designed to work with but only one at a time. You can usually set up a scan list that will roll through frequencies and they can be...

The Yaesu is a dual band radio but single VFO (tuner). The Icom and Kenwood you show are dual band, dual VFO (tuner). It's nuanced difference but a dual (or more) band radio with only one VFO can cover multiple bands but only do one at a time. That would be like the old FT-7900 or the current...

You'll find that with 4 AWG the SB175 is not your limitation. The SB175 data sheet references that their ratings are based on using wire with 105°C insulation. Keep in mind all of these charts assume indefinite lengths of time and that's not necessarily a true application assumption. Warn in...

ColCon are all 2m. I like having 70cm and here on the western slope it's pretty useful. The question comes up pretty frequently and the answer IMO comes down to budget and intention. There is no downside to having a radio cover multiple bands other than cost really. The radio isn't going...

Anderson SB175 using a 1/0 AWG terminal is rated to 280 amps in a wire-to-wire connection per UL. The CSA rating is 175 amp rating, as is the UL for a 3-pole configuration. These ratings are determined by duration and ambient temperature. Anderson has to assume an indefinite length of time...

The MC-58DM and KMC-32 (or similarly KMC-59) are not directly interchangeable and the differences are not trivial. The function assignments on pins 1 and 8 are different. These are Up and Down on the TM-261 while on newer radios pin 8 is serial keypad data and pin 1 is unused. The TM-261 uses...

I think your question is also about how quickly a person used to driving with right hand shifting can mirror learned muscle memory. Sit on the passenger side of your current stick shifts cars and try. The gear pattern is the same regardless of handedness. So to get 1st now is pull left, push...

Drive a stick long enough and eventually you'll have a clutch issue. It's inconvenient but not impossible to drive without a clutch. Commuting in any city without a clutch isn't an option of course but getting yourself off a track can be done fine.

The Handler 140 is a common machine and it's fine but I'd make the same suggestion as @krick3tt and consider spending the money to get a dual voltage (110/220) machine if you can swing it. When you get to 3/16" and thicker you start to push the limits of a 120V machine so you may have to do...
