So called "Premier Engine Builder makes Rookie Mistake"?

[poppaj]

Get out your glasses and magnifying glass:idea1:

Looks like both intake and exhaust was hitting, looks like eyebrows were not opened up near enough for valve size. From picture it appears that there was enough lift clearance. Think that piston is for a small valve -1 or SR head. Different piston used for 572 that allows for the larger valves. Think that might have been the problem.

adds up to me hemi-itis! nice eyebrows!

Yea,if those "eyebrows" were just a coupla thousands taller,we would not be talkin about this.:eusa_boohoo:

Made me nervous!

My engine builder is going over and above to make it right for me.
Just saw him yesterday and we went over the Titan Oil pump to make sure nothing was inside. Showed me the correct way to reassemble it. My Hemi block is getting bushed lifter bores next week. Rotating assembly is done, so next week might be a good one for the Hemi to be getting assembled.

 

[Cranky]

Do you assemble your own engines?

Do you assemble your own engines?

I use to , no time and no patience. Id rather be out there making money.With the knowledge these guys have and the specialty tools, I'll leave it to them.
I do everything else after the long block is assembled.

My hemi is just about done and going to get it next week, weather permitting. if all goes well and if the rain stops, I can have it ready for the valley on the 3oth.
Just have to weld on the tabs for my new engine motor plate, everything else is there.
Putting on my new edelbrock carbs done by Jake's automotive. hopefully we will see at least 9.20's out of the new bullet.

ARC has been working with me almost everyday and discussing converter, gear changes, and tuneups with the new 7530 digital 7 MSD box.
Lebanon Valley here i come!

Well the HEMI did not turn out very good. 7 passes and its smoking like a Chimney.Thought I'd bring this post back to the top because I should have gone with my gut and not went back to him.
65% leakdown on 4 cylinders, 47% on 2 cylinders,35% on the last 2 cylinders.
No crosshatch left, nice and shiney, and rings are shot.
Valves look like they have 100,00 miles on them.Valve guides leak oil, pushrod tubes leak oil into cylinders,
Alot of black material in the pan.
Its all apart and being redone the right way this time.Live and learn.
I wonder how the other HEMI'S he did are going to turn out?

Seeing stuff like this happen just kills me. I own an engine and machine shop and have for nearly 25 years. I deal with a lot of engine builders, locally and regionally. Believe me, I see a lot of stuff go wrong and sometimes it's just best to make a clean break and find a new set of eyes to have work on your stuff.

I have a particular customer that does a lot of work for racers who run Comp, Top Dragster and Top Sportsman. He sees engines originally built by many "top name" engine shops in the country. I could write a book on some of the things we have had to repair, and the things that led up to it.
Most of the end users, in these cases, have moved away from their original builders for a number of reasons, mostly because of unsolved problems, bad customer service and blatant overcharging for poor results.

As far as trying to sue...I hate to say it, but the judges often don't understand the nuances of the industry. Many shops will hide behind the "no warranty on race parts" clause. Often times the legal and court costs will eat up anything recovered, if you actually get someone to pay on a judgement.


On a side note; the pictures posted of that piston to vale clearance problem may not have been detected by the original builder for a number of reasons...
Most importantly, many guys "clay up" and rotate the engine to check piston to valve. The clay pushes the piston to rock away from the valve, measuring only the furthest clearance. It does not adequately represent a hot piston, rod stretch, and "loft", which is the piston skirt flexing and allowing the piston to rock further in the bore than you can represent while assembling.

In a nutshell; you need to rock the piston from underneath, during piston to valve interference timing events, while rotating it through the range if you are going to get a correct clay impression.

It's a common mistake, I just had to recut valve reliefs on pistons for a 655 wedge for this reason....the original builder missed it and the pistons even hit the heads enough to pinch the ring lands.

The wedge pistons that you saw were wrong, he put in 440-1 pistons instead of the correct 572-13 pistons. 572-13 have a 13 degree valve angle where the 440-1 heads have a 15 degree angle as you know. That was a mistake which i am over with.
But giving him another try with my hemi after the 1st attempt on the hemi deemed almost the same results. Smoking and slowing down weekend after weekend.
Went from a 9.69 to a miserable 9.98 and in bad air 10.04
Funny i have the build sheets for the Diamond Hemi pistons and it says upgraded wrist pins but upon disassembly it seems to have stock wrist pins.
