    What exactly is the stuff you put in the block?

  2. Should be nice to have to just focus mainly on the engine this winter. Happy hunting for a Donovan !

  3. it will be a nice break to only have to deal with the engine everything else looks good. hard block is like cement. look at lippys pic. the product adds strength stiffening the cylinders in the block making it solid. its poured into the water jackets. the rock block is a epoxy. it flows into the areas better. as it cures it expands slightly compressing the bore. it needs to be added prior to any machining. a race block is usually filled to the deck. mine being a street car will be filled to the frost plugs. I need some room for water. if I do get a Donovan billet block we will measure two inches down from the deck and two inches up from the register at the bottom. everything in between will be removed.

    Brian, that is what happens when a helper thinks he is putting alcohol in the warmup tank and in reality it is 104% nitro.He took the tank into the trailer. my brother had the gas bottle in his hand. I was in the car. The helper set the tank on the hat and plugged it in. We cranked it not knowing it was straight nitro in the tank, it was running on the gas bottle and my brother turned the valve on the tank on. The engine stuttered and died. We turned the tank off and xcratched our heads and figured it was just cold as it was cool that morning. So we didn't back it down. BIG MISTAKE. Nitro had puddled in the cyls. It rolled over I hit the mag, My brother never even had a chance to hit it with gas. We never dreamed that was straight nitro in the warmup tank. It banged real hard. One crank, one block, two heads and a bent frame tube. I asked our helper, Didn't that tank seem awful heavy? He said uh...yes it did. :(:mad: When a nitro engine is running they are safe. Not so when they are just sitting there. I called Henry Velasco and said, I'm gonna send out another crank. He said....you banged it didn't you? I said nevermind Henry.:p He said, did I tell you about the time I was standing in the staging lanes and someone banged one starting it in the lanes? I got a free ride to the ambulance. Someone said HENRY your bleeding he said, WTF? Schrapnel.

    A real good friend of mine is a nitro guru. He says, there's a thousand ways to skin a cat and the cat he don't like none of em. When in doubt, BACK IT DOWN!!

  6. i have seen some real disasters from guys not backing down a engine. the hemi guys have it easy. roll it over and done. everyone else has to pull plugs first. i have seen some guys get hurt backing a engine up without the mag disconnected. the bar came around and almost took the head off a guy another was lucky to only break a arm. the weight lippy is talking about is the weight of the fuel in the tank. a jug of nitro weighs about twice as much as a jug of alcohol. there should be no mistaking what you just picked up.

  7. I got the engine taken apart this weekend. To my surprise i found all of the small side bolts missing from the main caps on the passenger side only. One of the nuts was almost off of the stud. One cap was lifted off the block. I couldnt turn the engine over until i first removed five pistons. Number 1 and 3 i cant get out. They made it as far as the deck i also had to remove three caps and loosen the other two just to get the crank to turn. With the pistons out i could see the main webs. They are all severely cracked. Everytime the pan comes off we check bearings and torque. This thing was a bomb waiting to go off. Nitro can be a rough deal. Anyone out there that has a block 392 or 354 im in need. I have checked all my sources and came up with nothing. 20171022_150447.jpg 20171022_154630.jpg 20171022_154544.jpg 20171022_154603.jpg

    I'm worried how limited you will be with even a half hard blocked original core.
    How you ever gonna mix that bugger past 80% damn it?
    Whoa! how'd it go so fast that time? "It was in kill man!"

  11. I have done failure analysis on CAT truck engines , and the pics are interesting from what is shown. Time bomb waiting to happen? You bet, Looks like the finale blast was only seconds away.:(

    Brian, that is some serious ugliness! How much horsepower do you figure it was making? What was your redline? Do you think it got into detonation, or is that just from cylinder pressure and RPM? Good luck with a block. All I know of is a 331.

    Looks like you got every last penny's worth out of that block!

  14. I'm interested to see how bad it is after the crank is out. it gives me the creeps to think i was seconds away from making a pass.
    it looks like there was some bad vibration going on the way so many bolts had fallen out or came loose. when i took the oil pump off it was loose also. when i drained the oil there was rusty water mixed in it.
    its a good thing i had hot heads four bolt steel caps. i for sure would have driven over the crank without them. there is a famous pic of a fuel altered loosing a crank on the starting line. i don't want to be that guy.

  15. joel I'm thinking over 1500 plus to go that fast in a car thats 2400 lbs. i don't think we had a detonation issue. if we did we would have seen signs of that. things like broken pistons closed plug gaps pounded out rod bearings etc. too much timing and compression can be hard on the bottom end. for next year we will set it up to handle the nitro better. that being less of both of those things. remember no one else is trying to run a 50 percent nitro street car. there are no u-tube videos on how to do this. we have to experiment. we have a baseline established so we will focus on making changes based on our previous results. we have proven the ideas we had work. its now refining everything for longevity. when that happens there will be even more head scratchers out there wondering how they missed all of this. we keep the rpm around 6500. the dragster i work on turns at least 10,200 rpm to go 260 plus on a spec tire.

  18. I've got a block, but it's already been converted over to a different style of 4 bolt main caps, so probably no-go for what you need.

  21. The main caps. There are a few different styles out there including steel girdles.

  22. It had aluminum caps on the middle three mains, was a spare race block, so I was told. I made steel caps out of 1018 and it was line bored by NVR racing. 100_0099.JPG 100_0098.JPG 100_0095.JPG

    I'm working on the shipping part for one and it looks like $350 to $500 for shipping. Well as we all know speed aint cheap. Good luck in your search, and glad it didn't blow while going down the track.

    Is Rokblock not the same as Embeco 885?

    When you put a window in the side of them it makes a good place for the chain to go thru
