Intake manifold fitting

TBH i've never used a torque wrench on them - i just pull em up till they feel about right.
Once its been started, i find you can usally nip them up a little more when its warm.

You've made me famous!!!

(Seriously, I don't think that you can do anymore than that)

If you are really bored you could test the torque of one of your bolts, I bet its around 20 ftlbs!

I just fitted my new valley gasket and manifold last night.

Dunno what i waas doing wrong but i could only get two long bolts in (I'd dropped them when i'd set them out so messed up the order.

Put silicon round the water holes; used thread lock on the bolts and tightened them gradually - all up to 30lbs/ft as stated in the Haynes.

. . . Seems to be ok . . . ??? I hope

Hi

The installation instructions for the Edelbrock performer inlet manifolds recommend that the bolts are not tightened beyond 25 lbs/ft, and are torqued in a pattern starting in the centre and working outwards. If this is not followed, the manifold is liable to crack.

The standard SU or efi inlet manifold , however, can be pulled down to 30lbs/ft as recommended in the official documents.

Been there, done that...
