engine mounts in a 1983 f-150 4x4

I just bought these engine mounts to put a 460 in my 1983 f-150 4x4 using the 302 - 351 frame towers. They do not work without lots of cutting and shimming. http://cgi.ebay.com/ebaymotors/New-...ptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories

I have heard that they work, so I wanted to see if anybody else has had success with them.


I wanted to solid mount the engine, but after 1/2 a day screwing with these mounts I put the factory f-250 towers and mounts back in and it bolts right in. The trans adapt mounts needed about 1/2" to 3/4" of shims on each side between the block and mount so that they would sit against the towers on the frame correctly. Then in order for them to work you would either need to cut a notch in the frame perch so the engine would sit back another 2" to bolt up to the transmission, when the transmission was slid all the way forward in the crossmember.
