Re: If you like destruction -
OUCH. That sounds a lot like a cam going flat but I see you have a roller. Whatever happened is due to the way it was put together to happen that quickly. If its bearings I would suspect clearances were badly off.

Re: If you like destruction -
I took it to a more "reputable" machine shop after we tore it down, let me back up here a minute, during tear down we noticed the main bearings were scuffed some on the top side some on the bottom side. Then took it to the machine shop to check the line bore, now we found the problem, apparently the "other" shop was having some in house personal issues and the quality of work wasn't up to standards. After a phone call to them to discuss the line bore issue it still ended up being "my" problem. In the mean time they got the block corrected just waiting on the results of the crank, still may have to put a new crank in it.

May have missed it somewhere - perhaps another thread. Are these stock valves? Stock valves are two piece. The head is force welded to the stem. Right about where that gave way. Which is why I have always been a big advocate for quality one piece valves. Especially in a performance build. Relying on stock units with countless cycles on them is asking for trouble.

Re: If you like destruction -
The heads are Edelbrock RPM Marine oval ports - the valves are 'stock' to them. 2.25" one pc stainless intakes, 1.89" one pc Inconel exhausts.

Re: If you like destruction -
I see. Do those valve guides have c-clips on top? If so how does it look in the bad cylinder?

![]() Now it's just a waiting game until my 532 is finished, probably 8-10 weeks. I'll be back to burning rubber and banging gears this summer. I did call Derale about the fan issue and as expected, they 'have never heard of or seen this before', so I offered to send the guy the pics, of course he declined my offer, but was happy to give me the part number so I could buy a $130 replacement fan...

Re: If you like destruction -
Oh man. What a mess. Such a small part causing so much carnage. I'm worried your crank/bearings might be damaged from being beat up by the stresses of that event or even the metal bits. Check it for scuffing. I definitely wouldn't trust the connecting rod or pin in that cylinder. But the more you can salvage the better I guess.
As for the fan, yeah, welcome to the world of plastic junk these days. Even GM factory fans have been bitten by this. The Pontiac G8 and Chevy Caprice PPV fans have a tendency to fail like that, eventually shattering the blade and throwing bits into the radiator, poking a hole in it! People talk about it on the forums (and I can't remember if there is a TSB for it). I'll take the old fashioned bulletproof metal factory fans any day for the few HP the electric fans save. I've had too many failures like yours and burned up wiring harnesses, failed relays, etc. Factory clutch fan goes back on my builds. Then again, I don't have any high-rev applications either.

Re: If you like destruction -
The head can be fixed. A good machine shop that knows how to weld can fix it. The heads are Edelbrock? Did you bolt them on right out of the box? They are notorious for having tight guides, valves assembled with no oil on them, and installed spring heights way off. Looking at your picture of the valve stem stuck in the guide, it looks like the stem is blue from heat. Again that is just from the picture. If that is true then that would tell me that the valve was starting to gall from that above reasons. If this is true I think it hung a valve open and smacked a piston. the 2 piece valve snapped off and left you with the mess you have there. Thats what I see from the pictures.

Re: If you like destruction -
Yes, they are Edelbrock RPM oval port Marine heads, but not quite bolted on out of the box though. The marine heads don't come with valve springs. They had been ported, put on a flowbench (so I could get the cam spec'd to the heads) reassembled with Crower hardware (spings, retainers, locks) but re used the valves that came with the heads. The work on the heads was done at a shop, so I did not personally check the valves/guides. Once I get some more time, I'll disassemble the heads and try get a better look at the valve and the guide.

Re: If you like destruction -
Well that is a good thing then. That means that they were looked at and assembled with care (we hope). You made a good choice going that route.

Re: If you like destruction -
The short answer.. ABSOLUTELY repairable.
The aluminum head repair is a pretty common thing to upper end machine shops that build drag motors. (we're always bringing in carnage for them to fix) I've had a number of SBC aluminum heads (AFR and Brodix) heads repaired and they come out just fine. AFR and Edelbock alloy is a tough one to weld from what I hear. If you have issue finding someone more local, PM me and I'll put you in touch with a couple guys who will steer you right. Just make SURE they have experience doing aluminum head repair on aftermarket heads, Just any ol hack with a TIG and a die grinder isn't what your looking for.

Re: If you like destruction -
Heeeeeey!!! I wish I was as far along as your rebuild is (I'm SO glad you stayed with the big block!!!) Not much as of yet, machine work is complete for the shortblock, final assembly should begin soon. Then all the port work on heads & intake will take some time. I'm looking at probably the end of June. Transmission isn't finished yet either - so I've taken the time to redo some wiring, install a new fan controller and a few other things. Got all the Hotchkis stuff installed too.

Re: If you like destruction -
I finally got the transmission a couple of weeks ago, it's a TREMEC TKO-600, but with a full internal upgrade by Liberty Gears - polished & cryo-treated gears, bronze shift pads, carbon fiber synchros, threaded front cluster bearing support and PRO 5.0 shifter. It's going to be backed up by a RAM 10.5" twin disc clutch with an aluminum flywheel. Both will withstand 900hp. The 532" should be right at 800hp, so I have a little 'wiggle' room.

Re: If you like destruction -
I hate to disappoint but it's only 5 gears. I don't know about awesome, but I'm sure it will scare the hell out of me the first few times I hammer on it after it's all broken in. I'll be putting in a call tomorrow about the engine. It's supposed to be finished this month, as I had time set aside to go pick it up from their shop in TN.

Re: If you like destruction -
