Best original 307 Olds intake manifold for our 403

[Bob Dunahugh]

This is the Olds 307 aluminum intake manifold for my 403. This manifold was on 1982 to halfway through the production year of 1985 Olds. Most were in the Cutlass modal. The casting # is 22504068. The correct manifold must also have the A4 next to the thermostat housing. The intake produced after mid 1985 has smaller ports. Can someone post this to the NET group? Bob Dunahugh

Interesting, that there is another coolant temp port at the rear; the
77-78 Toro had this. Useful with a lot of gauges and EFI. Bruce Roe
