Hey guys im needing to know what motor mounts/perches I need to switch a 429 thunderjet into my old pickup. Truck had 390, I have everything else for the 429 except the motor mounts/perches. Any help would be appreciated

 

You'd need the 460 mounts. The 429 and 460 are both 385 family engines

 

I have a 429TJ in my 72 highboy thing hauls some butt even with 36's and 3.50 gears, you will be happy with the swap. I gernaded the stock dana 60 in the rear so start thinking about an upgrade. you can get motor mounts pretty easy from a lot of places i think mine are from L&L.

there is yet another option ...... you can use the 390 perches and stock 390 motor mounts i use these on my 420 hp 460 in red dawg and most of the mud trucks run these too.... my cousin Nathan has a NASTY 429 that he has ran for years with stock 390 motor mounts i have some pics and the other side http://www.uscconlinealbum.com/lifec...?th=450&tw=610 and my crude drawing of where you need to cut the motor mounts to make them fit and the 2 bolt holes on the 429 block you will need to bolt to (note you have to drill one of the holes a little larger on the 390 motor mount) this is at least what i would suggest to you since 390 motor mounts are only $15-$20
