What did you do to your non-G body project today? [2021]

[Supercharged111]

Slow day in the shop today so one of my guys helped me with this front plate. It had some metal ground out of the ring from the previous owner because of the slave cyl they were running.

Prepped and welded in the spots, and I machined it down flush and concentric. I'll fix the hole when I get it on the transmission. Should work fine to mount the LS slave cyl.

I'm still curious what kind of conglomeration that thing was running. LS front plate with LT input on an LT trans?

Howe short Slave Cyl from what they said, haven't looked into it. LT Bell Housing, push-type Pressure Plate Clutch setup on the back of a BBC.

Weird. I would think the LT external slave should work here too?

Not without the pull type pressure plate. LS front plate has no clearance for the LT fork.

Can you not do a pull type PP with a big block? Or was it his preference to run an LS type clutch?

From what he explained it was push type because of how the hydraulics fit in the car. I didn't pay attention too much because my main concern was thinking of how to fix that front plate properly.

I have an unopened LT1 T56 behind my long crank LQ4, QT LT1 steel bell, used the Howe T5 conversion TOB, normal LS T56 clutch and a Mcloed long crank flywheel.

But I don't know how theyd use a pull style clutch or LT bell behind a BBC because the BBC was 168 tooth flywheel and the LT1 was 153 tooth. A 168 tooth won't fit in a LT1 bell unless you go caveman on it and cut the bottom of the bell out.

So if a guy were to try and stick an LT T56 behind a GenIII 5.3, he'd only need to run a regular T56 clutch/fw (maybe a crank spacer too?) with T5 conversion TOB?

And apparently LS stuff bolts to a big block?

I ask because these are 2 scenarios I'll likely face at some point and want to know what all my options are.

LS stuff can't go on BBC/SBC or long crank stuff because the LS input shaft is longer and will extend into the crank.

I don't know if a LT1 or long crank trans would fit behind an LS with a short crank. I'm pretty sure the actual face of the flywheel is in the same place on the long and short crank stuff but the pilot bearing bore will be closer to the block on the short crank Gen 3 LS stuff so I'm not sure the input shaft of the LT trans will go into it. Not sure if the crank spacer moves the pilot bore back. I assume no because T400's need those crank snout extenders to pilot the converter into the Gen 3 cranks.

Sorry, I meant LS clutch stuff bolts to a big block? Or maybe dude was using an aftermarket bell to fit the bigger flywheel. I suppose I could just Google how to make a T56 work behind a big block, sounds like there's a few challenges I wasn't tracking.
