Not to revive an old thread but I decided to swap out cams on this car. Currently I have:
Lunati custom grind Solid Roller cam
Advertised duration 293/297
Gross Valve lift .627/.600 lift
Lobe seperation 107*/104*
comes close to one of their Dirt Track 4000-8000 rpm cams.
I was thinking of this cam for more drivability
Advertised Duration (Int/Exh): 279/285
Duration @ .050 (Int/Exh): 249/255
Gross Valve Lift (Int/Exh): .585/.600
Valve Lash (Int/Exh): 016/016
RPM Range: 2800-7200
What do you think?
BTW here is the motor in case you forgot.
383 Stroker motor bored out 4.065 (389 stroker)

|cobalt327||Hydraulic TOB adjustment is usually done by screwing the bearing in or out to set the gap. Some setups also use shims. In any event, if this is incorrect the TOB piston can bottom out against the retainer before the pedal travel is used up. This will cause hydraulic fluid to leak out around the seal.|

Also I have a hydraulic throwout bearing, would that still be a pedal adjustment? Cause I would try that before removing the tranny.

Did you clean off all the anti corrosion oil from the new flywheel and clutch pressure plate before installing the clutch.?
Clutch pedal adjustment.

If the oil pan gasket, oil filter, oil cooler hoses, dry sump pump
rear main sear, front seal, timing cover, valve covers, back of the intake, oil pressure gauge sender, oil galley plugs in the back of the block
if any are leaking oil, oil can and will get on the clutch. if the front input shaft seal on the trans is leaking trans oil will get on the clutch.

cleaning oil from a friction surface usually involves brake cleans for the pressure plate and flywheel.and usually a garbage can for the disc.If it was a stock engine I would heat the disc with a torch,careful to avoid the springs.
you can try brakekleens and sandpaper, I wouldnt

As far as break in, it said no hard launches for 500 miles. I havent launched the car as of yet. This was 3rd gear slippage.

|cobalt327||Clutches need to be broken in properly, just like brakes. And adjusted correctly. And no oil, etc. on the friction surfaces from the engine or tranny or even from over lubing the pilot.|
