LS powered 510s are not exactly unheard of. With a little work with a BFH it fits. If i recall correctly theres a clearance issue with the steering rack, but a 240z rack and some 280z spindles drops the rack enough to clear for VG30s, and thats a big ass motor, so you might want to look into that, but you have to make some space in the trans tunnel, and I think folks usually move the firewall back 4ish inches. Ive seen it, and its about the coolest car/motor combo imaginable.
