This is the date code on a 427 side oiler hydraulic lifter block I’m looking at buying.
It looks to be a 72 service block date coded to Jan 27th. What does the “W” above it denote? There are nose casting numbers on either side other than 12 DIF
Thanks Royce. I’m gonna squint and say I think I see an 8 instead of a 9J17 and say that makes it correct for my Feb 68 GT-E.
Supposedly it’s been properly preserved and on a shelf since the 70’s after having been pulled from a wreck.
Probably worth the risk.
No. There arent any ribs on either side
But the possibility that those are 2 dots under first number made me think that 1st number could be a 2. Hence at 72 service block.
Thank you Royce
Since I trust your expertise and opinions on FEs in general and implicitly as related to GT-Es, does it sound like to you that this is an early 69 service block and assuming no major issues, suitable for a non-concourse GT-E restoration?
The recently rebuilt (less than 1hr total run time on it) solid lifter 65 top oiler currently in my GT-E is not producing adequate oil pressure ( 30psi cold, dropping to 10 or lower at idle at temp).
Assuming the engine will probably need to come out to check for bearing clearances, I thought it prudent to try to source a hydraulic side-oiler for it. This one can probably be had for about $2k.
