Intake torque and pattern?

[Brap_Brap]

Does anyone happen to have, or know of a site that has our intake manifold's torque and pattern specs?

[anorak] 30lbf, there isn't a pattern as such but I'd work from the middle outwards. [/anorak]

Don't know whether you're talking about manifold-to-heads or trumpet-base-to-manifold or plenum-to-trumpet-base, but none of them are very high (aluminium is soft) and generally you work from the center outwards tightening them all up progressively.

Thanks, now I can get my engine back together today or tomorrow.

Mr Haynes says 30 lbft for the manifold-to-head bolts, to give you some idea. The others are smaller so would need correspondingly less torque.

Tighten them all down till the threads strip, then back off half a turn
