What's up?! Piston higher than the rest.

Small problem and easily fixed. I would never suggest shortening a piston.

ran my 472 like that no issues.

I would have no issue at all running it that way. Carry on.............

Been reading some posts, I have encountered engine machining that was like done by morons around here!! I saw a brand New Circle track short Block (very xopensive) go to our ??Local best race shop HA!!) and it came back honed out of tolerance I measured one bore and piston wall was over .008 thou yet the others were way less!! Also from air flow research a set of heads with valve retainers so hard I could tap one with a hammer and it would brake in half ,,,OF course they denied any wrongdoing (part was never drawn back or annealed correctly) Brand new engine dropped a valve cause the top valve retainer just broke in half.. Should make these monkeys take a apprenticeship as machinists or something before they are allowed to hang there shingle so to speak...!!!! I do understand every one has there level of expertise but for someone to make a living doing things totally wrong with no recourse is shameful. Hence my feeble attempts to do most everything myself.

Update: Shop called. Block has been decked off the crank centerline. All pistons out of the hole .015. Deck is square. Head put on for checking valve to piston clearence. Had almost .250 at max lift showing on the clay. Cleaned the block, reassembled, come and get it.

Me happy.

personally for my thats unacceptable they would be getting me another block or I would get a refund and FIND another machine shop, now this is a Bastardized combo....

this is what Iam talking about

he bought the block from a member, the deck was at a slant on one bank when he got it, the machine shop just "squared it up" with his blessing.

It will run fine this way I ran one out of the hole .020 and it hauled ass...............

sorry, post # 8

It will be fine, just get some thicker cometic head gaskets and let-r-rip.

Coug, I've searched the internet and talked with those I trust and everyone to a man has said run it you'll be fine. What's your beef?

I have no Beef it just seems that 90% of the people on here would rather cobble a mess together than to do it right....I would have junked the block and found one that would have worked.... it's not like it was a special block or something Rare.....

I think a good set of 4 bolt caps were installed on this block.

It's a good .060 over 4 bolt Dove block with a super nice set of custom made 4 bolt caps. It's now square and if I wanted to change pistons I would have as nice a Dove block as anyone out there. Don't think I'll be scraping this one yet.

Thanks,

Frank

Yeah darn junk. Go get yourself something nice and send that junk over to me.

Seriously, good to see you caught the issue and got it corrected. So much of failure vs. success is attention to detail, checking everything is clearanced, and machined correctly!

We all have to remember that during the years of production, Ford used three different deck heights to the best of my knowledge. They had blocks speced at 10.280", then some at 10.300" and then some more at 10.320". So that's a range of .040".

Diamond pistons tells everyone in their catalog,,,that their compression height numbers are based on a 10.300" deck with the piston .005" in the hole. Guess what? With a true 10.280" deck height, the pistons would be .015" out of the hole,,,,and that's where Frank is now.

Thanks Charlie. I believe you nailed it. Take that Coug.
