'78 intake manifold part number ??
« on: February 23, 2008, 09:22:22 AM »
I'm looking for the part number(s) for an OEM 1978 intake manifold, WS6 W72  Anyone know this or have a source? Thanks!

It's in John Witzke's paper on the W72 performance package.  That intake was the same on all the T/A's with a 400 engine.  Part number 10003395.

Are you sure it's not 525355?  That would be a '77.

78 is 10003395, 725355 is 77.  Where are you getting the number from?

Go here for John's terrific paper.

Ok, I just looked at the intake I bought and it has no. 10003395 and date code H167 (Aug. 16, 1977). This will be correct for a 1978 Trans Am, right? Thanks again, Bob.

Yes, that's correct for a 78 400
