A nice early issued assembly line fan shroud,that's unmolested & was originally used on 1969 & 1970 Big Block Chevelles w/3 core rad.,albeit dusty.
The transmission type did not matter.
1969 427cid. COPO's would've come with this shroud,as their 3 core radiator was the biggest they had until the 1970 4 core PA,PD was available.
This shroud has never been reproduced,and was issued for only 2 years,before the redesigned 2pc. took it's place during 1971 production.
It's a one piece design & has it's part of #3938165 cast into it and is 3 core specific for the BC,BE,BW,BK,BO,BJ,BQ & BR Harrison radiators.
All corners are intact.No cracks,no holes,no excuses & more importantly,it has never been shaved down,which most surviving are today to fit the 4 core and then show an open gap there once installed.My finger is pointing to the critical 1" lip on drivers side & bottom.
This shroud will help achieve the maximum cooling possible as well as earn points at any judged show.Most are using the current reproduced later #914 shroud that was designed for a 4 core and has the lip cutout.That 1" lip cutout shows up as daylight,where this has the 1' lip to fill it in.This also has the correct original bottom corner jog,where todays repro #914 does not.

*NOTE:Big Block PA,PD coded 4 core air conditioned equipped Chevelles,or heavy duty PA,PD equipped Chevelles did not and can not use this shroud,due to the plastic overhang digging into the 4th cooling row.

Technicallly those used shroud #3976653.
.....but because chevrolet was late in having them available,they took my #165 shroud and shaved it down on the assembly line,to fit the 4 core.
The #653 shroud was soon replaced with the #6261914 years later,and that's the only one they're selling today.
