Advanced Hemi 212cc Predator Build

Well I used the bushing like thing that positions the gasket to protect something. (Dowel pin?)

I used a carbide burr to get up in there.

Glad I'm late for work so I don't rush and mess this up.
Borrowed a camera.
Seems more workable now.

Even considered drilling then cutting off a drill bit. Putting a nut around the remaining drill bit, and then welding bolt, the bit, and the nut.

Just try the easy out first.

The block goes for $40 free shipping on eBay, just in case!

Will do!

In my experience, with clean, new stuff, they work like 95% of the time.

I think it depends on whether it broke from bottoming out in which case it'll be a bear to get out, or just straight up broke from a bolt failure which should almost screw out with your fingers. You really can't go wrong if blocks are $40, just go for it and learn something. $40 is a pretty cheap education.

Then what will we have to read while Bob waits on shipping!

Exactly what I was thinking....but the ease out is worth a try.

I think you should try the EZ out Bob!

 

[bob58o]

I will try the easy out. I think it bottomed out???
40 bucks isn't bad. At this point, I would say $99 for a new block (with new crank and piston ) wouldn't be bad! It would also come with a new head to play with.

At least my head is ok.
I mean the cylinder head, with MY head, we all know there are issues!

 

[Flyinhillbilly]

No worries, I think I speak for all of us when I say GAB nation. Just do what you gotta do and we'll be here watching and waiting.

Gab natioooooooooon!!!!

My neighbors dog just had puppies. I can steal one, shoot it, and mail it to you if it'll help.

Seriously though, I'd try the left hand drill bit first, an if that didn't work I'd weld a nut to what's left of the bolt.

After you mail the dog, maybe you can weld my head onto my block.
Joking.

I actually ordered the block already.
If I get it out, I'll have a block, an exhaust, an air box, a cam shaft, valves, valve springs, connecting rod, carb, valve retainers,....

Would still need a crank, lifters, pushrods, rockers, piston with rings, head w valve cover, gas tank, throttle plate....

Guessing shopping for those needed parts would be more expensive than $100 bucks.

Stock replacement parts are cheap, but so is $99 for an engine.

i have no idea why I am now trying to see what I need for another compete engine.
That's not til 2017, when I build a space ship.

With a spare block, think of GAB possibilities. Bored Cylinder, bigger piston, stroker crank shaft... Like NASCAR Ray likes to say, "No replacement for Displacement; Where's my Bud Light???"
Lol

Flywheel, recoil, .....

I should buy brand new Predators to part out on eBay! Lol

After 6 months of online research, I still can't turn a bolt!

You know what I could use an extra block for?????
DIY VACUUM CLEANER FLOW BENCH!

Well since it was slow, I got to go home early.

I guess I will re-jet the carb. I got lots of jets and lots of drill bits.
I think I wanted to be around .028" Pilot Jet and 0.041" Main jet, From previous suggestions and research.

I may start with the 0.028" pilot jet, and maybe a 0.042" main jet. I have more main jets than pilot jets and would rather start rich than lean.

I'll try to set the idle with the 0.028 pilot and see how the plug looks after a WOT run with the 0.042" main.

Or maybe start with 0.025" pilot and go up?
And like 0.044" main and go down??

Now I have to find that chart I made.

 

[bob58o]

What I do best is "Pull Out!"
Two minutes after it came out, I got notified that my block has shipped!

I suppose a $#!+ ton of spare parts isn't a bad thing if I start giving these toys away to my nephews. 4 nephews plus me is 5 vehicles. I've got two started.... Maybe I'm stuck using clones!

Now put your bolts back in without the head or gasket and lightly bottom them out and measure the difference left and compare that to your head and gasket.

 

[bob58o]

My tap set is not metric, but I can put a bolt in the threads. I didn't try to tighten it.

Now what????

Pull the piston, the crank, Rod, cam, lifters????

Put all in new block???

Should I get the stud kit now?
There are also bolt kits.

I wonder if hardware stores will have studs/bolts to fit?

 

[Poboy kartman]

What I was getting at was to see if the failure was because the bolt bottomed out! Your block should be fine.

HF Tap and die sets are CHEAP, and come in handy!

 

[bob58o]

Head thickness at bolt holes is 30mm.
Bolts bottomed out by hand leaves 28.5 mm coming out
Gasket is extra 0.5mm.
30.5mm seems like it should be good? For those bolts?

 

[bob58o]

The good.

 

[bob58o]

And the GAB'd..

 

[Poboy kartman]

Are you saying you can't properly thread a bolt in that hole? If so, what is your concern?

I asked a lot of this just to try to diagnose what caused the bolt failure. Probably mainly a flaw in the bolt itself. I don't think that's a bottom out problem...but washers wouldn't hurt .Also...even though you're running higher compression I would back off the torque a pound or two.

Consider this: a big part of those torque values are based on what it takes to crush a thicker gasket and compress it enough to keep it from blowing out. A thinner gasket needs less pressure, no?
