Welcome aboard Patrick. Down under eh? Do the toilets really flush in the opposite direction than ours? Just kidding mate.

Are you saying you only have the supercharger and manifold? I'm sure I could find a block here, but I would really hate to see what it would cost to ship that to you.

Wouldn't it be easier to find a Series 2 L67 from your more common Holden?

What year is your Buick?

Lol I think its your toilets that flush backwards! N yeah I already have what we call a ser2 3800 block n heads to bolt the m62 on plus the ser1 coolant pipe. To suit the rear thermostat housing on the inlet manifold but I need the relocated alternator and tension pulley setup to to make it all work and the fuel rail with pressure reg and throttle body+ maf sensor setup and probably the wire loom plus comp? I think we must have had lower emission standards cos we don't use the mass air flow sensors or exhaust recirculation system till the ser3 3800 our ecotech

I'm not even sure Series 1 accessories will even FIT on a Series 2 block. Last I knew, none of the big stuff was even compatible with each other. I do know that you can cross over parts all day long between the Series 2 L36 and the Series 2 L67.

Even if it did work, your better off getting the Series 2 supercharger(M90) vs the M63. Your going to probably lose power with the incompatibility.

Well no cos the inlet manifolds are different from l27 to l36 I need ser1 l67 parts they bolt on the l27 no issue (our ser 2 is your l27) not the l36 that'* what we call an ecotech if I was doin one of them then I'd need ser2 L67 parts
