Uhh...I called him and said "Im pushing about 1200hp at the flywheel with a 4l80e in a 5000lb truck", and he said ok I think I have one that will work well for you

Mentioned it would probably stall around 3600, but I dont really care about that unless its super super loose.

 

Bama boys need updates on your **** !!! How's the new verter?

 

Unfortunately....things arent so good.

Notice some low oil pressure so I cut the filter open...


Also tested the trans, and it has low pressure in every gear, so it needs to come out as well...

But I took it to the track today to get a final run in, and this is with only 17lbs with a 12lb launch on a bummed trans...be sure and listen to the speaker

Still runs good on a bad day!


I am hopeful though, I knew it wasnt going to last forever at this power level. Although I am bit irritated at the engine issues (I think the crank is bent...), when I get it back to 100% its going to be a beast with this converter and turbo!

 

Damn, sorry to see that. Hopepfully it didnt put any filings in the turbo.

Do you have your mains pinned? That's one thing I didn't do that I wish I would have.

 

Sucks man, maybe it won't be to bad to get it straightened back out. Got to make some passes in my car this weekend at i22 but hopefully ill get the mini-tub and suspension done this month and ill get to come out and play with y'all.

 

I have been watching this thread from the beginning and I feel your pain every time something has gone wrong. 100% my favorite truck of all time.

 

Truck sounded freaking great going down the track. The ladder is classic.

 

Sorry to see this, but gotta say for a busted up truck she still moves the f out! Lookin forward to phase 4 or 5 or whatever you are on now too.

 

Why do you think the crank is bent? I would check it with a degree wheel and a dial indicator before you pull it out and once you get the heads off. I assume you would have already expected to do that though.

 

This is the second engine I have had this crank in that showed the exact same symptoms...low oil pressure but still runs perfect. Completely new block. I plan to check it with it still in there. Hoping to have it out this week. Just dropped off the trans at blakes.
