WildCat 223 performance build

Starting to screw this 223 together. This engine, like building any stroker, it takes time and patience. If you have any questions about the build, email me at [e-mail] and put “Gray Goat” in the subject line

[@alexlacroix9515]

If you spin the bolts into the aluminum case fast the threads will fall apart and come out. I wish I would have heard your comment about not using power tools to assemble. I found out the expensive way that cast aluminum will not take the abuse that the steel Chevy blocks that I was taught to assemble engines on. I was always very carefully using my 3/8 impact and never cross threaded or even let the gun impact but just the speed would cause the threads to start falling apart. It pays to listen to the Greygoat.

Hi You doing Eric.You do great work and I only order all my parts from OMB wear house.

[@jacobsebastien3910]

The Wildcat 223 is a Strong Well made block' Much Better than the predator 224'

[@michaelg7862]

Where do we purchase that tool to hold the crank from spinning when installing flywheel?

[@nerdypup3014]

Where. Am I locate one of these straight edges you used with this build? I’ve looked and can only find large ones. I appreciate your help!

[@MustafaKingHutchinson]

How do you do the timing on these engines?

[@bougieba9767]

What size rod did you use mines had clearance issues

[@garycrandall1652]

Never saw any main bearings. No plastic gage?

[@Strict30]

What rod did you use

[@Strict30]

Can heads that fit 212s fit on that engine?

[@timberripper]

Would you be willing to help me diagnose why my 223 wildcat wont wont. No one can figure out why

[@jimmycooper7248]

I'm doing about the same build but with stock piston and EC + .050" rod. What cam did you use to not have to put pockets in piston please? also what did you end up cutting head?

[@TheGrayGoatGarage]

I used the CM grind cam...also known as the HOT 265 or Super X cam www.ombwarehouse.com/super-x-dyno-cam.html You need to check the valve to piston clearance with any cam going into this engine. I got greedy and milled the head .060" and wound up having to use a piston with eyebrows cut into it. All of these engines have different tolerances. You have to make sure all of the clearances with your parts will work for you. Each engine must be built individually! I was using the +.020" rod and the taller .570 piston.

[@jimmycooper7248]

Thank you sir. Your help will have me buying more parts from you. My gut tells me that's the same cam that comes in the Tillotson 225rs. Thinking of a Black Momba for mine

[@user-gt3xx6lc1o]

Looks like head studs could be longer

[@jovonfryar5694]

What is the pointer on the rod cap used for

[@MrBill35]

oil sling

[@Exclusv]

Should I use blue or red loctite on head studs on a 212?

[@TheGrayGoatGarage]

No loctite. Snug them in dry by hand

[@Exclusv]

@@TheGrayGoatGarage so I shouldn’t torque them to anything just install by hand until tight? They won’t come loose?

[@callofdutymobilegameplaywi7217]

I’m building a similar performance build 223cc hemi electric start … I’m using the new high compression ec carb forged piston rod 5.583 and I’m wondering would the tillotson electric start billet flywheel fit this motor it’s an arc 6679 part number fits gx200 196cc clone tillotson electric start billet flywheel last piece of the puzzle to figure out

[@TheGrayGoatGarage]

Yes. The 6679 will fit the crank but you need to make sure it clears the block. ARC made some changes to that flywheel to clear Tillotson blocks, but you still need to check it

[@bougieba9767]

Do u like the forged better than the arc billet one?

[@bobbycarter9796]

Will a 223 crank fit a 212 block with a little work. Thanks Lord B less

[@ryanmannracing22]

If the block your using is a Hemi predator then yes it will fit but you will need a flywheel and rod from a gx200 or a Ducar motor

[@ryanmannracing22]

Also there is some clearance issues inside the block

[@jaystrappa]

What piston did you use Mr. Goat?

[@jacobsebastien3910]

I'm pretty sure the stock flat top Piston

[@frank2887]

What's the stock rockers ratio on the wildcat ?

[@TheGrayGoatGarage]

The stock rockers are a 1:1 ratio

[@MrBill35]

Wondering why you didn't remove the " ninja star " ?

[@TheGrayGoatGarage]

I am conflicted with the ninja star...and real life ninjas! It serves no purpose, but if it helps sling more oil then maybe it is not a bad thing to have there. Due to its placement, it may help get more oil mist to the top of the engine. I have no empirical data and no real way to test that...but in theory, maybe it is best to leave those on! I dunno!

[@johnjamce1146]

what is the max power will the stock case can handle

[@TheGrayGoatGarage]

This block is very similar to the Tillotson 212 block with more material supporting the side cover and head. I would have no issue saying the block will handle 24 HP

[@marcalampi5036]

@@TheGrayGoatGarage that's a lot of power

[@user-pl1ju8ht2o]

why no more video's about the wildcat 223 ?

[@TheGrayGoatGarage]

Since the Predator 224 came out the interest in that engine has diminished If you need help with anything you can email me at [e-mail] and I will do my best to help you

[@datriontucker6474]

Can I get a parts list on this build?

[@TheGrayGoatGarage]

Send me an email at [e-mail]. This engine went to a racer we support. He has yet to have this much power! The most important and time consuming part of this build is porting the head. The runners are narrow and a lot of room for improvement. A lot if material was removed!

[@RedfishInc]

How you doing Goat? Been a while since you've done a video.

[@TheGrayGoatGarage]

The Goat is old and tired! We have been crazy busy since the pandemic started. There are a lot of big kids pulling projects out of the barn! Things are just now starting to get back to normal. I will be doing more videos soon! I promise!

Are those lifters stock length???

Yes, those are stock length lifters.
