have a 99 monte carlo 3.1 anyone knows if im able just to add the upper manifold,will it fit,i think there is lesser screws,bolts but will it work at least for now till get time to open and replace complete,anyways i just replaced 1month ago the bottom gasket,please help

 

Im pretty sure you can swap the upper intake from a 3400 to the 3100.

 

thx i cant wait to see the difference it will make,btw nice ride,i wanna paint at least my top intake mani and the valve covers but,i havent been able to do so.like the way ur is,looks good,thanks

 

How much difference is expected from the swap?

 

and by the way nice car matt

 

port the 3400 upper intake and get a 65mm TB if u wanna see a big difference....
