i have a VH45 that im putting in an old holden, it came out of an old tank mercedes and it absolutely hauled!!! these are the best engines. LS1/anything holden can go to hell, i love my VH. they're extremely light and the sound........
to answer an earlier question, they're a 90degree V so they're extremely wide, fits nice and snug in an HZ engine bay so would be a very very tight fit in a stag but they've been fitted in skylines before so i guess its not impossible.
id love to do a VH41 AWD transplant one day, only thing holding me back is the lack of easy manual conversion options. adaptor plates have been made and a few one offs have been made but nothing that doesnt need a bit of stuffing around yet. also, from what iv read, the VH41 are the better engines as these were built for the jap market not the US like the 45s but the good thing is that the internals are all interchangable so you can take the better VH41 and stroke it to 4.5 with the VH45 rods and pistons. worth doing because the sumps are different between the 41 and 45 so you cant just bolt the AWD sump to a 45.
