Hq block with fuel injection top

Would I be better chasing a Hj block so the turbo 400 bolts straight up?, would it have to be a pre 1/75 block or any Hj would be ok? Cheers

TH400 will bolt up to any VN-VSIII block. But yes you are better off with a red 308 block, just try to get one cast 1976 or earlier to be on the safe side. Has to be a TH pattern block though, manual red 308 blocks won't work with a TH400. Note that the cast date on VR-early VS blocks appear the same as mid 1970's blocks.....enough said.
