Anyone know this intake??
 

It's an aluminum, rectangular port BBC casting #3919851. It's tapped for a temperature sender with the heater hose port at the front and has a casting date of 5/21/67. These features are consistent with the date. None of my reference material shows this casting number. Was it actually used in a production model or was it just an over-the-counter part? https://www.yenko.net/ubbthreads/imag...s/confused.gif

I would guess it to be over the counter, considering the 849,850,852 all go to corvettes but no listings of a 851??? But the 849 is for a 390hp oval port, maybe the 851 was for the over the counter square port??? Plus all the casting numbers above are for the 68 model year??? Good luck, hope this helps, Mark https://www.yenko.net/ubbthreads/imag...lins/beers.gif
