Thanks for the imput, after closer inspection I found no #'s or letters around the thermostat housing,but I did find a * with a circle around it followed by D1. The date code was 189. The total width is 12". There was no date of manufacture on the under side heat transfer. It has the cut out for the choke tubes,but no bolt holes for the throttle linkage. Is it possible it came off a 330SB? The bolt pattern and angles look the same. My 350 has a extra hole for a thermaticaly activated vacume switch.

I recently found a 1965 olds intake manifold with a square bolt pattern. I was wondering if it would fit on my 1971 350. The only info I could find said it was for a 400BB but the width is the same as my SB. The casting # is 387691. Any help would be appriciated.

I recently puchased a 1965 4bbl intake from an olds SB, it has a square bolt pattern the man.# is 387691 I wanted to put it in my 71 cutlass 350 SB. I was wondering if it would fit. The only info I found said the only such intake was on a 428 BB. I was hoping a edelbrock 1406 carburator would work with it. Any help would be appriciated.
