Did you not pressure test for leaks on the cooler?

No doubt its a beast for sure, cant wait to see it run.
That's kind of what I was thinking. Or the welds were weak. I'm sure it put down nice numbers though lol

I did not pressure test it. I figured it would would be good to 30psi. I was wrong... lol. It's getting fixed and then back to dyno tuning.

So I have to ask, do you have video when that let go? I know what it sounds like when an intercooler boot blows off the Powerstroke that I daily and it'll catch you off guard to say the least..

I know from experience what blowing a coupler off sounds like and what blowing the end tank off an intercooler sounds like at 26psi ! It will scare the shit out of you ! Especially when you're not expecting it .I had that happen to my old 99 GSX , blew the end tank apart at 26psi with Precision 35R .

Just because it Can be done doesn't mean it Should be done. The bottom end can't take 30 psi for very long. Just asking for trouble.

No but working at a machine shop for over a year I've seen it several times
From too much boost? Or a spun bearing? Bent rod? I have a pretty decent bottom end, even if it's a stock block. It's got really good diamond pistons ( made for up to 30psi) Callie's crank and rods

I am curious why there would be a hole in the block as well. There are plenty of people running 1300+ on stock blocks. I would think it would lift the heads before grenading. Either way I don't doubt you will see the numbers you want and that is one sick engine bay!

Usually a hole in the block is from the rod bolts breaking & chunking the rod out the block, a stock block can handle more power than most think as long as nothing fails, you can break a rhs or any other after market block with little HP when something fails

I think it's safe to say that anything can handle a lot of power as long as nothing fails :dunno:

I'm saying I know someone that is running a stock block in a FI fbody with a good rotating assembly @ 1500hp and has been running it @ the track for several years and occasionally street driving & never had a issue
