Dtret Posted May 22, 2022 Share Posted May 22, 2022 Can you guys tell from these pictures what year Monte this is off of. Guy says big block Monte w/ a/c. Thinking about it for the pos 70 only cuz it cheap enough. I can still sell it if I don’t fix the car. Thanks Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted May 22, 2022 Share Posted May 22, 2022 Looks to be a 70. Large radiator opening, 4 bolt top plate. Big block or small block, they are the same. Except for the non hd cooling,small radiator, 3 bolt top plate core support. Quote Link to comment Share on other sites More sharing options...
Dtret Posted May 22, 2022 Author Share Posted May 22, 2022 Thanks Tom. 70 was what I was looking for. I was worried about the headlight holes. I know 71/72 are different. But I’ve never seen them side by side to compare I don’t know if it’s a glaring difference or just slight. Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted May 22, 2022 Share Posted May 22, 2022 You're welcome Dennis. Just a slight difference. The headlight bucket holes are closer to the outside of the support on a 71 and the 72 being just like the 71 but with 2 holes between the radiator opening and the headlight bucket holes for the grille's turn signal bulb sockets.

Dtret Posted May 23, 2022 Author Share Posted May 23, 2022 I just reread the Facebook add Greg sent me and it says the core support is a 71. Quote Link to comment Share on other sites More sharing options...

714024SPEED Posted May 23, 2022 Share Posted May 23, 2022 It is an HD cooling support. If you look at the bottom where the driver's side radiator tank sits it has the extra tab welded on for the larger tanks. The top plate would also have the extra tab. 1 Quote Link to comment Share on other sites More sharing options...

For you Chevelle guys it would be the equivalent to an LS6 radiator support. 1 Quote Link to comment Share on other sites More sharing options...
