wont the conversion mounts still work?

RE: 4x4, 4.3L to ls1 5.3 need assistance
 

2WD and 4x4 have different motor mounts... At least when dealing with the V8 swap...

RE: 4x4, 4.3L to ls1 5.3 need assistance
 

the motor mounts are the same part # soi'm pretty sure that the mounts would work and i believe the headers he sells would work too.

i was looking at a picture of his motor mounts and i don't thing that the 2.8 frame mounts will bolt up but the spacing might work out on the metal part that bolts up to the block

this is a picture of his mount and i can't really tell how it bolts up it looks like a three bolt patern but i'd have to go up there and check it out i think i'll do that to seeif it works i'm in the middle of that swap i have those mounts i can go see if my conversion mounts will bolt up to his lower mount. I'll find out

Theres a picture of a 4wd LS swap its in a newer body style the pans crazy if you wanna keep 4wd you gotta spend the money on that kind of stuff

RE: 4x4, 4.3L to ls1 5.3 need assistance
 

okay so i went to autozone and had them pull the motor mount for a 91 4X4 4.3L blazer and i took my swap motor mount for an LS motor and it fit there was a little play between the swap mount and the motor mount but 1 washer on each side and you'd be good. Hope this helps

RE: 4x4, 4.3L to ls1 5.3 need assistance
 

Yep, us 4x4 people have a lot more work with a V8 swap than 2WD people :D
Even more so if we're a 5-speed!

I know one guy had to get extensions welded on the 2WD mounts in his 4x4 for it to work properly...

RE: 4x4, 4.3L to ls1 5.3 need assistance
 

So i was thinking about the motor mount i went and saw at autozone that B mounts to the motor so he has a solid bottom part that mounts to the frame that has that 4 bolt patern same as the 2.8 frame mount motor mounts so i dunno about the vertical part but it would bolt right up. The bolt holes are sloted in the lower part of the swap mount and if you swap them around right you can get the slots to be vertical so you can adjust where the motor sits up or down

RE: 4x4, 4.3L to ls1 5.3 need assistance
 

You don't really need any up/down adjustment... You need forward/back...

With the LSx swap, you might even be able to get away without hammering the crap out of the firewall, lol.

Also, apparently, the 2.8 mounts are the strongest that were put in the s-series...

Though Energy Suspension has poly 4.3 mounts now.
