I know the mounts will need to be taller than the stock .15 big block mounts.
Correct on the Impulse, Mount just bolt on. Impact & Vector Has eccentric mounting on the chassis. Lookin' on both chassis( which I have in frt of me) Vector mounts can be interchangeable to mount .21 engine. Bolt pattern to chassis are the same. Cant remember if 950 will fit.
