Are there any kits out there to do a Chevy swap that have bolt-on engine mounts are are they all weld-on?

I think you want Weldon to reinforce the frame. It’s just not designed for mounts in that area.

I was just curious if there were any kits out there that were a bolt-to-frame engine mount.
Not that I’m aware of, sorry

Usually you bolt them up to get them aligned then weld them in … you could feasibly increase the hole size to get a stronger bolt in there … however it would take a welder not too much time at all (very low cost ) to just roll under and weld them up after your engine and all is setup

Most traditional conversion kits like Downey and AA are welded in. The mounts usually land in spots where the factory frame holes are, so scab plates are welded in to cover the holes and then the mounts can be attached. I guess you could figure out some way to bolt them in, but as Johnny mentioned, they'll need to be welded at some point. Those kits requires the driveline to be moved forward and the driveshafts will need to be a altered along with other things. I think the Marks kit keeps the driveline at the stk location and uses the stk rear bellhousing mounts, but the frt engine mounts will need to be welded in. I have no personal experience with this kit.
Well good question. There are kits for various v8 motors to bolt into whatever that use saddles or ubolts etc to secure the mount, crappy IMO.
When my LS was installed we used stock GM mounts, IIRC the frame side pieces are available from GM. Mine are welded in but you could bolt them to frame given a proper support area & bolted correctly to prevent crush and/or shear. I suppose any or most of the aftermarket units could be done the same way. Basically once you discover what it takes to succesfully bolt in a motor mount you decide to plate & weld. Thats not to say it cant be done though.

The Downey kit I bought years ago hit right over a hole in the frame rail. I found a piece of angle iron that would span the hole and fabricated a new frame side mount that I could bolt to the frame with two bolts on each side of the hole in the frame. Done in the mid 80's and still holding up just fine.
