Stuck a camera down a couple spark plug holes, appears to have 020 Pistons in it. I see a bunch of paint parks on the crank that I need to check out after dinner.
 
Weiand makes a street warrior that seems to work well, used one on my cheap 454. I am helping a buddy build a super budget 454 with peanut ports. Hopefully soon we will have dyno numbers.

Weld on a nut, helicoil the crank.

I am going to build a 496 for the car I am building into a dad hotrod.
 
Tried welding two different nuts, neither held. I'm not sure if it's worth trying again?
 
Yeah grade 5 steel nuts. I got them hot enough to glow red. Hell I've never had the welder turned up that high before. The held pretty damn good but that bolt is bound up.

Damn its like fused in there I bet. Its ugly from here on out. We know that with a nut welded on it wont budge. This means without a doubt an ez out wont work. Drilling through grade 8 is awful. Thats really what it needs, a big enough hole for it to become weak.

If you could get the motor some how situted so it doesnt move you could source a bucks drill with a big steel angle and itd hog that thing right out. Its not an easy set up but it could be done. This is tough man. Its no big deal if the crank was out but thats a shit load of probably unanticipated work. Theres an 8.1l in molesto...
 
carbide bit in a die grinder and hold on tightly, was the only way I could drill the D60 stud. You can try drilling a hole, heat it with a torch, then burn another nut on. Hopefully the weld melts into the hole and to the nut. If that doesn't work, a no other way of welding a nut to it will. (unless you start playing with fire and cold water, which I know nothing about) The carbide will still cut through the weld if it doesn't work, meaning an EZ out can still be tried. Get the biggest EZ out that fits and use the carbide to drill the hole out for it.

also, are we sure the crank is worth saving?

edit: make sure everything is clean, grind the end of the bolt a little for fresh steal.
 
I don't think an ez out is going to touch this.

Not looking forward to drilling at all.

And yes the engine is in good shape as far as I can tell and I have receipts showing the engine was rebuilt. It just needed seals and freeze plugs.

Hate to pull the crank to have it machined but that may be my best option.

Need to sleep on it.
