I checked with Performabuilt who built the trans before putting it in. It's a level 2 with a 2800 stall and comes with a good warranty.

Were they using the synthetic or conventional B&M?

the original conventional trick shift.i used the stuff myself in one of my 700's and it did make it shift harder,but the transmission didnt last to long.but then again none of mine were ever fully built either so who knows

Got the old engine on the work bench for disassembly, the new motor is soda blasted, ready for a hone, paint, freeze plugs, cam bearings

This is going to be awesome.

More pics soon.

EDIT: Oh yeah, the rod caps came off with 40ftlbs! Should be 37 and 90 degrees...

This motor was very poorly built, so glad we had the mishap with the rain.

Not only were the rod caps loose, but it took just over 60ftlb to remove the mains. All the bearings are trashed, the crank is .020 under on the main pins, .010 under on the rod pins and .040" over on the bore. All are too loose for our standards, we don't build or sell anything that's more than .010" on the crank and that's the max bore. Basically the block, crank and pistons will have to go to the scrapper. There's no salvaging any of it. Pistons are scuffed like no tomorrow The cam bearings have never been replaced as the Babbitt is showing on the entire surface.

Ont the bright side, we are comparing the 120k mile donor motor, and everything is to spec, block doesn't even need an over-bore and we just happen to have a .010" under crank

ARP rod bolts will be used, stock mains to avoid the align hone needed for main studs. Clevite bearings are in order (not 77's here folks), and the wider late model SBC cam bearing will be installed.

Here's the bearings after 10k miles of use, now you see our concern with running over 11:1scr...

Trick shift (aka type f fluid) has higher sulfur content than other trans fluids and makes gm clutches unhappy. I've seen it on mine and other gm stuff, makes them slip. Went back to standard fluid and no more problems. May or may not jive with performabuilt's stuff depending on where they got their clutches. Some aftermarket stuff will tolerate it.

Teflon coated cam bearings are in, just popped the freeze plugs, secret rod bearings are being test fitted

Hard to believe the car has been stored for so long. Time sure does fly.

How is everyone?
