Keith Morganstein,

Just as Cammer means nothing to you Keith Morganstein means nothing to me.

Have a good day!

We are just running around in circles.

As a professional I can not advocate compromised engineering practices.

Buy the proper rods for your race engine, the bores will be round, and you will be happy!

540 RAT, Please do not quote me out of context. My original statement was: "Bearings used on the connecting rod big end are eccentric to facilitate the formation of an oil wedge. This type of bearing is known as a Delta-wall bearing." I was merely making a general statement about eccentric...

I will repeat this one more time: Proper connecting rod bores are round! If you machine a rod big end on the mean dimension and round you will avoid spun bearings assuming clearances and mating parts are correct. Contact your bearing or connecting rod manufacturer for clarification! Bring old Grumpy...

Proper connecting rod bores are round. Bearings used on the connecting rod big end are eccentric to facilitate the formation of an oil wedge. This type of bearing is known as a Delta-wall bearing. Care must be taken to maintain a good surface finish as this promotes heat transfer away from the beari...

Engguy, Combining a torque wrench with feel adds extra uncertainty to an already dicey proposition. What are you going to believe, the torque wrench or your feel? I do not recommend hand tightening any critical engine parts. Hand tightening carburetor fasteners is much different than hand tightening...

Race engines can present unique threaded fastener tension problems due to special machining employed. Machining processes changing the angular relationship between mating parts (joint face angularity) can contribute to fastener face angularity problems. If the fastener/washer/nut face contacts at an...

You guys should have started with Mercedes' dropping quality ratings!

David Redszus,

What years did you build BMW engines for the Firehawk IMSA series? Where is your engine shop located?

Please tell us about the rest of the fuel system.

Given information presented, I would start with the carburetor you have on new combo, and dare I say it, maybe try more carburetor!

Yes folks, you can run a carburetor without a thousand dollars of work done to it and be a winner!

Opening up the whole torque/tightening/tension subject field is a bag of snakes! Tightening by feel = +/- 35% Torque wrench= +/- 25% These figures are within a few percent of those quoted by most engineers. I have seen experienced assemblers tightening by feel beat torque wrench numbers! Measuring b...

A few years back when checking camshafts on an Adcole I had blueprints and full specifications on every camshaft and checked to this data. I was working in prove design engineering at the time and we were trying to sort supplier camshafts for a new engine design. I see manufacturers like CompCams to...

I am fully aware how various industries calibrate and certify tools.

My question was directed to SpeedTalk members and the methods employed in their shops.

I would like to ask members how you verify your torque wrenches are accurate?

Do you send wrenches to a certified lab or use in-house testing and certification processes?

Is there a certification label on the torque wrenches you are using?

The "Black Art" is the constant changes taking place in an operating internal combustion engine. Everyone out there needs to understand that a great deal of what we know about internal combustion engines is based on theory! Pull out any automotive engineering text and note all the "id...

Many running roll cages on the street think they have extra protection.

Think about it!
