This is always a area of concern on my 68 327 L-30...In 68 the L-30 uses a pressed on balancer with NO bolt..The crank is not even drilled for one...Kind of scary on the top end..I guess I'll know when it decides to part with the crank...

<font color="blue">I have 3 early 327 cranks. I have drilled & tapped all of them.
I would never take the chance after all these years
of having it launch through the radiator, tires, hood, firewall, etc. @ 8000+ rpm. </font>

THERE IS NOTHING LIKE SOMETHING COMING LOOSE AT SPEED. STILL A TEENAGER, I MUST'VE HURRIED THROUGH AN ENGINE SWAP A WEEK EARLIER WITHOUT COMPLETELY TIGHTENING THE RADIATOR. SATURDAY NIGHT ON OCEAN PARKWAY AT ABOUT 75MPH, MY 65 IMPALA SS VERT 4SPD LAUNCHED THE RADIATOR INTO THE FAN, IT WAS JUST A FIZZING SOUND, LIKE TIN CANS IN A BLENDER. COULDNT SEE THE CAR BEHIND ME, NOTHING BUT STEAM ASTERN.
SINCE I WAS ON THE PARKWAY, I COULD NOT USE MY OWN WRECKER AND PAID TWICE AS MUCH FOR THE TOW AS THE REPLACEMENT RADIATOR.
I ALWAYS CHECK MY NUTS (AT LEAST) TWICE NOW.
