Need your honest opinions

I am getting the trans rebuilt on my 86 GN in a few weeks, and i just got the fever bad...
I am thinking about bolting on a te-60, and throwing in a 3000 LU with the fresh trans.
My question to all of you is, how well will my stock rod motor hold up? The motor has about 50k with .020 over forged wiseco pistons, 204/214 cam, stock headers/crossover, stock heads and stock DP. rear is the 3.42 posi and i am going to put a new fuel pump and tank in. Any feedback is greatly appreciated, the overall goal on this car is to have a good daily driven car that will go 11's.

I'd want to see at least 200K on it before I complained.

I've got a 70 on one stock motored car that ran 11's years ago and now has 200K on it.

I'd be more worried about who and how the cam. and bearing install was done, rather than 11 second power on a daily driver.

A TE60 and 3000 stall "should" be good for 11s. I would get Alky, a wideband O2 and Powerlogger. Oh, and a good set of drag radials.

my dad and i rebuilt the motor ourselves, i have had to rebearing it due to
fuel flooding the oil but the motor still runs great with great oil pressure. the motor has seen 5500 to 6000 many times no issues

New or used turbo? What brand converter?

If fuel flooded the engine you shouldnt need bearings. A re-ringing would be needed but the bearings should be ok.

it got so bad that the oil lost its lubricative properties and the bearings ate themselves still holds the same amount of vacuum as it did when it was rebuilt so i dont think it needs rings

Unless you're beating the hell out of it all the time I think it will be fine. The tune is probably more important than anything.

Did the cylinders get filled with fuel somehow?

 

[baby6]

thanks for the input guys. yes the night it happened i was coming back from the track and
i had it running a little rich..i tuned the tt chip to be rich but what it does is
lengthens the injector pulse and flooded it.

That's not enough to hurt the bearings. It would have to have had an injector open and the fuel pump on and filled the cylinders with gas which would leak past the rings and fill the crankcase. It would take a lot of gas to do so. The cylinder would lock when you attempted to crank over. The ring seal would go away fast. I've seen engines filled with gas from errors and be fine after changing the oil. If you have bearing issues if look deeper. Post pics of bad bearings here.

this is how it went down. i was on my way back from the track, i was messin around on
the highway in drive boosting it and letting off multiple times (yeah i know i was stupid) and when i got off i
noticed my oil pressure was really low. i changed the oil in the morning which reeked like fuel, and within minutes it was down again.
dropped the pan, thrre was a handful of gold flakes and all the bearings were wiped. i got the slight marks out of the crank, put new bearongs in it and its been fine ever since with great oil pressurrle, idk what happened.

 

[twodafloor]

Is that a flat tappet cam or Roller?

 

[baby6]

flat tappet

 

[baby6]

Anybody know what may have caused the bearings to wipe? I still have yet to find out. TTT
