I no longer have the sticker but from what I recall it was the same size as the 88. I’d be in for a full set 90cali emissions. I need two other sets but need to confirm years
Yes 3-1/3: 1 325k miles low but even compression,1-long block unknown miles, 2- mid 200k miles low 100 compression. Average runners but great rebuildable cores.
There are minor differences on the thermostat housing over the life of the of the 3F 88-92. The vsv’s are part of this change I have seen differences changes in 90 not necessarily in the 60 to 80 series change. dont just chase out the thread
