Hq block with fuel injection top

[Innuendo]

Any engine swap in NSW must match the pollution requirements of the year of engine or car manufacture.

I have a '79 308 in an '85 Jaguar and it had to go 100% LPG because the engine didn't meet the '85 ADR's.

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

They won't have a clue if you use a hj, x or z block. They all use the same engine number prefix. They don't look at clock cast dates.

You could have used a black 5 litre block.

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.

Byron could you explain exactly why a vt roller block is a problem for adr27 holdens, as i were getting ready to build one for the HJ GTS/4, but use vl brock heads and get a early roller cam from herberts usa

It is a problem for pre ADR27, ADR27 or ADR27A,B,C etc as you have to comply with the emissions requirements for a VSIII/VT, which means standard EFI top end, ECU, memcal, cats etc etc. You have to use the whole VSIII/VT engine, complete with ULP fiuller neck etc. No mods, no cam change, no memcal change etc.

I see, so after its decked and lost its numbers, and early topend fitted, is there any other external features that give it away, apart from 308 on the side of the block.

Hi, so roughly a QT and 11QT what numbers would they go up to before they hit the early 1976. Cheers

11/75 was 695000 there abouts
