    The engine is going back together intake machined and now sets level with head at VC rails. Took about .100" off the pushrods as they were up in the pocket of rocker arm not hitting but very close, like to see a couple threads below rocker. The distributor now sets more centered in it's bore as well. So it should be ready for testing now as long as nothing else shows up. Used Cometic gaskets for intake I like them for the way they fit only a couple $ more than others. They also have a nice tacky surface to them.

    Damn, engine porn. Sure looks good. And, with the dizzy more centered, less wear on the drive.

    Yup, done that a couple of times - makes ya smile when you see the intake isn't standing proud over the head. Nice. Haven't used the Cometic intake gaskets on anything yet, but they look composite, correct? Sizewise, how's the port match?

    Yes it does. Composite, yup. Size is good on width, nice up top, bottom are below port probably to make work with low riser head as well. They also offer different thickness gaskets if needed.

    Well a little bit of an update. Engine back together however still gets water in oil under pressure so into further investigation. Damn it.
    No time to go work on it this weekend have family up from NC staying with me. The girls play volleyball and travel all over the states, it's a club thing.
    Will get down soon after to check things out in the mean time Joe will see what he can find. He's just happy that it's mine as I understand running into these issues. Still no fun when it happens.
    Guess I did a good showing on business as supposed to be an offer coming next week on it.

    One H*ll of a day !!!
    Received videos of pressure test of cooling system in engine using air. Water leaks found one in valley area and one up thru head bolt in front top of #1 cylinder. Never seen one leaking in valley before down near lifter web. Will maybe look to see if just a porosity but done with this block.
    Planned to go down to shop Friday so we could get it going up until the videos came in and changed thinking. So now I will take the original 428 block down and see what pistons I need to get so it can be back in the ride. Reuse as much as we can from this build and get it going again. Did a quick check on the bores with my bore gauge and all looked straight but will redo when down at shop before proceeding. Then order pistons and get the block work finished up to restart. So now we will go for more cubes!! At least will be back numbers matching a real 428 CJ stroked up !
    Think will have to do pressure check first thing. Just disappointed all around right now. But at least have a plan.
    The best made plans of men and mice!!!

    Went down to shop yesterday. Stripped the stroker down and evaluated all the parts. Other than the crack in block nothing hurt. Mounted 428 up on stand and bore gauged it all nice and straight so ordered new pistons for it. They should arrive next week sometime and then the machine work can resume to get this one back together. Will have a few more cubes now.
    Just realized when I did the aluminum heads, to save the original heads I refused to dig into this engine so I wouldn't go crazy stroking it at that time, yet here I am!!!
    Also the guys are bugging my buddy to come Pro Stock racing with them and he's still turning it down. So I said why not do the closer races here on the east coast you know like within a days ride. Not sure but I may be a bad influence !! Or is that a good influence .... Hmmmm.
    The crack is hard to see there is a minor black arrow on left side that runs to the right across the block, almost the whole picture width.

    They are tough to find - the mag powder plus the angle makes it almost impossible for the powder to "show" the crack
    Oh, well, more cubes isn't really a bad thing ;)
    Have a great Easter

    Happy Easter !
    Wasn't the egg I wanted to find, but more cubes OK !
    Does that mean bigger cam? Just kidding of course current cam will be big enough. Won't be able to run it out at track anyway. Should of already been enough power to require safety equipment that I won't do to this ride. It's just a toy !!!
