What is the best way to properly torque the bolts for the manifolds (235ci)? My torque wrench won't fit in there and I'm not aware of any adapter that would help... any suggestions?

Neil,

Here's my two cents. Although these bolts probably do have a torque spec in a book somewhere, it really isn't critical. Tighten them all the same..by feel. Pull on your wrench and duplicate that effort with each one, you would be surprised how consistent the human body can be. It's the old fashioned way to do it.

You need a 9/16" crowsfoot adapter, redily available from the flaps or your favorite tool dealer (Snap-On, Mac, Matco, etc) The specs are as follows, inside bolts next to heat riser-25-30 ft/lbs, oustide and middle bolts-15-20 ft/lbs. I also swappwd out the 2 end studs for the exhaust manifolt out to bolts, and torqued them to 15-20 ft/lbs to help prevent exhaust leaks at he ends. You should be able to get to most of the bolts with a regulat socket, it's the inside bolts that get tricky and require the crowsfoot.

Thanks for the help! Stuart, that's what I had figured and what I had done for now. 30 ft-lbs didn't seem like much and I figured as long as I tightened them the same I should be all set. Longbox, I had always wondered what a crowsfoot was used for!!! That makes perfect sense... I never understood why you would have a use for that tool. Thanks again for the replies and help!

Crows feet are really designed for use to torque hydraulic fittings but, yes, they are handy in situations like the manifold bolts.
