150" dout it will pass NHRA tech, It's a record holding sand digger built by Jon Sorg,from what I'm told it still holds the record

Whats your local track say? Are they just concerned that you stay under a certain speed?
My buddy has one sitting in a custum enclosed trailer. Last ran in the mid 80's. Doug Nash trans and 8 3/4 rear. Kinda a big undertaking. All one off hand built.
Keep us posted

Thanks WR,,ended up being a rear main bearing/case and crank issues

flywheel was tight too

I was not the original builder but I'm guessing the fit of this bearing was off

It didn't spin but was loose in the case,and pounded the piss out of it

Your thoughts Guys??????? Thanks,

Case is not as bad as expected gonna get fixed with a line bore and thrust cut,crank is going to get turned too

I'm glad it can be saved

Don't have it in front of me but I think it's a stock AE# welded behind #3
