Don't want to use up the good will with you guys with parts
books but can anyone tell me what this smog pulley is for.
The pump it's off date codes the '69 model year. Corvette?
Part # 3917234.
Thanks Guys!

Thanks Darren,
I bought a smog pump/pulley/divertor valve off ebay recently.
The seller had it listed incorrectly as possibly being frome a LT-1 deuce.
The date on the pump was given to me as 98th day of 1968 so I new that wasn't right.
It turns out it was the 298th day as the gang stamp must have been driven more to one side than the other & the 2 was hard to make out. no big deal, I thought that date would be a '69 model as it's around Oct. 25th of '68.
The divertor valve is stamped 29199.
Can anyone decode that number?
Thanks to all http://www.yenko.net/ubbthreads/images/graemlins/burnout.gif

I show it as fitting 68 Chevy II, Camaro (396) (exc. Sp. H/Per., C.A.C.) which means L34 not L78.
