This car was purchased with the intention of making a fun street car. Recently a local shop (On long island New York) has been asking that I put the car together for a shot at the stock short/long block record. The shop will remain anonymous as they are not a current sponsor on ls1tech. A majority of this work is done in my garage with the help of some very skilled people.

If any specifics are incorrect please mention it to me. I am unsure of what is considered “stock” or acceptably modified stock parts.

Nice car mine is almost exactly the same but has lq9 and gt88. Wiring and turbo kit done.by maxxmitchell and skinnies the record holder we will have mine out later this year already blew up a lq4 so switching to the lq9 now

 

Hmmmm??? another Spoolin_Notch lol

 

I'm guessing you are replacing bearings also? I don't consider it a contender for the stock shortblock record with different bearings/rings. The car should fly though.

 

Stock shortblock....Aren't they all....

 

Stock bearings skinnies

 

humble beginnings




Stock bearings, i still have the stock piston rings. They have been marked for each bore / top / bottom. Is there an official or accepted set of rules? Is there a stock rotating assembly record?

 

The 4.56 gears may only get you to the eighth.(unless you only plan to run a mid 10 in the quarter)

We have a 33" tall tire in the 3rd gen, and our 4.10s that are in it are going to run out before the quarter.

Also with the 4.56 gears and the 2.48 first gear of the T400, if you can get it to hook, then the power it takes to get a good sixty is going to make it impossible to keep the front end on the ground. You may need to leave in second gear, and then only go to the eighth.

A quick calculation shows a 30 inch tall tire only gets you to 133 and that would be with no slip in the converter considered, and a tire taller than it looks like you are running.

Keep the build pics coming.

 

The 4.56 gears were a leftover from when the car was a allout N/A car. They will be changed out as the build progresses.

 

Should fly! any idea on what the car will weigh?

Far from a stock shortblock if you have ARP rod bolts.. Do people really not know what "stock" is??

 

From another thread....

Can we start calling this the "stock rotating assembly record"?
It would at least end all the BS arguing.

 

I don't see why people have to fill his thread full of bs. Keep your opinions about if it is, or isn't a stock short block to yourself! Anyways nice build keep the pics coming!

 

1st post:


I think he would like opinions.

 

Hasn't really been any BS, it's been acceptable for years that replacing rod bolts are ok, but rings/bearings or modifying the crank/rods/pistons or mixing/matching parts isn't. The argument came up years ago when tirefryin freshened up a motor and it wasn't considered a contender for stock shortblock anymore. My shortblock is completely stock down to rod bolts, stock oil pump, stock timing chain, stock crank/rods/pistons/rings/bearings, etc. The only thing we did to the motor was head studs, head gaskets, good springs/pushrods, small cam, that is it.

 

Are you reusing your bearings ? I've always was under the impression that was not a good thing to do ?

 

id reuse any bearing if they looked good.

 

the only thing i see keeping it from a being a true stock shortblock contender is the rings. I mean when people cam their car, they usually do an oil pump and its still considered stock shortblock. So as long as you havent touched the actual rotating assembly (crank, rods pistons, bearings, rings) its pretty much stock.

Look at where most of these motors fail, usually a combo of the stock piston/rings..

 

If you have an untouched bottom end its stock... If you took it apart it is no longer stock... Its just factory PARTS you are using. So technically you could send everything out to get cryo'd and have everything balanced perfect... and have a decent bottom end and still claim its stock.... BS. You take it apart and its no longer stock. -My opinion.
