I read in SC that you can get the GM aluminum heat insulator plate from GM still. Can anyone reference a part number? This is for a square bore.

Thnx in advance.

p/n 3969837 for a spreadbore/Q-jet, Im looking for my refrence book now, I'll post again if I find the # for the square one. Jon

Gene, I think what you're looking for is in the Year One catalog.

They are also available from another source: Holley sells both square and spreadbore shields.

Guys, thnx. I feel a little embarassed http://www.chevelles.com/forum/redface.gif. Sitting on the can this am http://www.chevelles.com/forum/mad.gif , perusing the Fisher/Waar book, I saw the picture of a 425HP 427 with the insulator plate.
