1  Camaro Research Group Discussion / Originality / Re: 69 Z28 Crankshaft number on: April 19, 2015, 11:14:13 AM

So do we know what the difference between cranks is?

Per Jerry MacNeish's '69 Z/28 Fact Book...

"The 1969 302 crankshaft (part number 3941176) is identical to the one used in the 1968 model year (large journal).  This is a tuftrided forged-steel crankshaft."

Does that mean a 3279 crank is the same as a 1178?? Keyway and all? And Just different balancers and timing chain covers???

So if the 68 - 69 Crank have the same Identical  keyway,  the 69 style 7708  Balancer and timing cover will time out correctly, it should work great.

I got time to check the crank today, is has been turned .010-.010  w/Clevite  Bearings that look great, I'm just curious as to how this Crank is in the engine and why, I see no reason for someone to just change a Crankshaft  unless they spun a bearing long ago and really damaged it, but doesn't seem normal to install  something different than what it was built with, if it was built with an 1178 Crank, one would think  the same part would be used.
  I can understand going thru an engine to freshen it with new rings, bearings, turn the crank etc.,  so I am thinking they freshened up what they had and assembled it., who knows,  I have seen a lot of mismatched parts from cars built back then, I know if a certain part was not immediately available the assembly line did not stop to wait on it, they used  what was immediately available.

Looking at what remains of the vin stamp it's either 19N555219 or 19N556219, both indicate a Dec of '68 Norwood built Z, 551863-569987.

Block date code is K148 which is Nov 14, '68 so date stamp on block could appropriately be V1121DZ, Nov 21.

I sold a V1121DZ ,, VIN. 549121, to a guy in N.Y , couple years ago,

If I understand the change, and the reason correctly, then the crankshaft keyway itself is likely NOT different from '68 to '69, but instead the timing MARK on the damper, along with the position of the Timing Index (on the timing cover) are rotated slightly (10 deg or so) in order to be more visible and easier to see/adjust the timing.   If I'm not understanding this correctly even now, someone PLEASE correct me explicity ..  Smiley  If that is correct, then it would be the damper and the timing cover that 'go together'.. with the crank keyway position being consistent over the years.

I'm glad you brought this up about timing, it has the  69 style ,#7708 Balancer and timing cover setup, w/offset timing mark, so, is the crank  keyway  the same from 68 to 69 crankshaft, if so then timing will be correct with these parts.
I may need to call Jerry M. to be sure.

Hi, the V11 15DZ is date, not vin,  the vin. should be on the pad before the date

I recently tore down an early build,, 69 Z28 302 engine, everything was very correct except it had a #3279 Crank, is it possible the 68 Z28 Crank carried over into some early build 69 engines.,,,

Thanks

That is an early build, just ahead of mine.
