Engine suggestions

Get both beads broke loose.

Look inside the wheel, you will see the smaller area in the middle.

You can squeeze both sides of the tire in 1 spot and push it up into the smaller area of the wheel. If you can't hold it, use a big pair of vise grips.

Then you should be able to get the opposite side (180*) of the tire started.

Smaller wheel and tires, can be a pita.

Wow, today I finally decided to suffer through it and after what felt like wrestling an alligator I got it on.

@BrownStainRacing I got a yerf dog live axle off of craigslist and it came with a predator 212 non hemi with a clutch. Of course, it barely pulls with the clutch from a stop so I have a torque converter coming in tomorrow. How can I make more torque on the non hemi?

SWEET!!!!!!

VERY COOL !!!

You will love that live axle.

Yerf dogs are tuff, but steering can be a problem, if somebody over loaded it and got stuff bent up front.

Get that t/c on, in stock form and see what you have to start with.

Nothing wrong with a non hemi headed pred. They can make more torque with less money over a hemi head.

Lmk what rpm stall you have (after t/c installed CORRECTLY) and max rpm in high,......then we know what direction to go.

Good job, young fella, I like it !!!!!!!

WOW! That torque converter has done sooo much to the torque it's actually incredible. With the clutch, it was hard to even get started off on flat ground, but now it can basically start at the bottom of a hill and pull up it. I did notice that from 0 it pulls really hard but after that initial pull it kinda falls off in torque. I guess that's just due to the tiller engine design of the pred 212. Even so, I am absolutely amazed with how well this big yerf dog is pulling with the torque converter. It is SO much fun in the dirt with that live axle and torque converter!

It's night right now, so tomorrow I'll show you a pic of my install to make sure its right, and get my tach off my hemi one wheel peel kart to check rpm stall.

That's because those Hilliard clutches ARE NOT designed for offroard or stop-n-go use, they are essentially race only clutches by fault of design

Thats just how torque is with any engine, but playing with alternative final drive ratios can help.

In the simplest of terms, the more grunt you have down low, the less top speed you'll have; the more top speed you gear for the more strain you'll put on the TC, the faster youll trash belts, and it goes without saying the slower the launch and less able to climb hills it will be.

Default stall on the driver stock should be right around 2200-2800, I do know they run zinc weights.

Not sure what your final drive is, but 6:1 is considered the golden ratio to use or stay relatively near

How tall are your back tires???

What size is the driven (big pulley) 6" or 7" ???

Stock engines fall off on the high side with big tires and the 6" driven, because of the .90:1 over drive when it goes into high.

The 7" driven has 1.12:1 in high and doesn't pull the engine down.....as bad.

Work with what you have now and learn how the t/c acts with small adjustments.

You can move the driven spring from the middle hole to the hole farthest counter clock wise and it will tighten it up not allowing it to shift so fast into high.

This allows the engine to build power before the driven goes into high, making it pull better in the mid range.

You can also take out 1 stock driver spring and replace it with 1 white spring. This will allow the engine to stall up the driver to about 2600 rpm before it starts moving the tires. This puts more torque to the tires and less falling on its face when it gets into high.

2 white springs, will be around 3100 rpm, but you need to have more then 3600 rpm outta the governor.

That dover coil still good off the hemi???

If so, put it on the non hemi and set coil air gap to .045" with the stock non hemi flywheel. You can't interchange flywheels from the hemi to the non hemi, different crankshaft taper.
Here those driver springs, you can find them anywhere.
