Hey
Can weld ........ not quite as nice and clean as yours - but enough - the front crossmember was welded in by yours truly.
Had figured this might be what I need to do on the frame side => to connect engine .... but need a way to bring the actual engine mount forward on engine itself.
Most of the stock LS engine side mount brackets are for SBC. So I think worst case I will go with something like the one linked ... or get some SBC engine mounts ...

Just not sure if a better way ....
