But he has to blow up the stuff he has first. That is all we can do. As each piece fails from racing, build it back as strong as we can.
I want to see you have success not failure Wiz.
You do not get into building engines from a bare block like I have and Gunny.
With Hardcore gone, He is not coming back to DC I tried.
I am the only one that has Built Race Engine LS Engines from a Bare Block. Then on the Chassis rollers. Tuned . Full Flogged to 180-200 mph Rear wheels speeds in 4th high gear pulled to 7,000+ Rpms.
Then Sunday Raced at Route 66 or Indiana US 30 Track.
My Shit Held Together & did not Blow up.
The Rear C5 Diff is not the problem I am concerned about.
Nor the 4L60E.
I know both are going to fail catastrophic.
Its the 2,000-2,500 stall torque converter will BALLOON EXPAND THE MAIN STEEL SHELL ITSELF.
WITH FLYWHEEL HORSEPOWER AND TORQUE NUMBERS AT 500-550 HP & ABOVE IT HAPPENS.
IT HAPPENS WITH 700R4, 4L60E, TH350, TH400, MOPAR 727 TORQUEFLITE, FOR C4 & C6, GM POWERGLIDE .
The Ballooned converter shell expands.
The Torque Tube Corvettes are locked down solid to the engine flywheel flexpate & to the torque conveter drive plate.
Splined on both ends the you tighten down the swage lock bolts on both ends.
Rubber or poly biscuits the torque tube ball bearings are supported on internal.
Opposite reaction pushes through the torque tube driveshaft .
Right to the LS Flexplate.
Right to the the LS Crankshaft.
Right to the LS Crankshaft Thrust Bearing.
ITS SEVERAL THOUSANDS POUNDS OF FORCE BEING TRANSMITTED BACK.
A BIG BLOCK CHEVY CRANKSHAFT THRUST BEARING CAN ONLY TAKE 200-300LBS OF CONSTANT FORCE BEING APPLIED BEFORE IT FAILS.
100 LBS FOR A LONG LIFE.
PONTIAC 455 HAS 3-1/4" MAINS SO THRUST BEARING IS VERY LARGE. TAKE ABOUT 500 LBS OF FORCE BEFORE IT BURNS UP.
LS ENGINES HAVE SMALL MAINS AND THRUST BEARINGS.
THERE IS NO WIGGLE ROOM.
TAKE 150-200LBS CRANKSHAFT THRUST FORCE ONLY BEFORE IT BURNS UP AND DESTROYED.
THE CRANKSHAFT THEN STRIKES THE MAIN WEBS OF THE BLOCK & #3 MAIN BEARING CAP.
HOLY FUCK ALL IS DESTROYED IN SECONDS.
JUST REUSE THE HEADS AGAIN.
