BBC to LSX motor mounts
 

Does any body make them or am i going to have to go from BBC to SBC then to LSX

Nobodys done a BBC to LSX swap

Would be easier to help if you gave more info on the swap...what year truck are you wanting to put an ls in that came with a bbc?

Both are for SBC. Found the SBC to LSX but no BBC to LSX. I may just have to adapt from BBC to SBC then to LSX

the ones i listed will work for you. the sbc and bbc set on the same mount on the truck your asking about.

Even if it started out as a diesel?

if you look at your mounts that are bolted to your frame, they are the padded part with the hole in the middle for your motor mount bolt. that pad excepts the deisel and sbc and bbc engine mount to slide over it and then put your long bolt through it.....

just buy a set of the mounts i listed and bolt the flat plate to your new ls engine, drop over your existing truck pad and slide your long bolt through and put the nut on it and your dun. i took the deisel engine out of my old 95' 2500 truck and put a bbc in its place years ago then sold it to a friend. he pulled the bbc out and bought a set of the mounts i listed for you and dropped the 5.3 right in :)

Ok thanks for the info just wanted to be sure before i dropped the money on them
