What torque setting should I use when tightening the bolts connecting the upper to the lower intake manifold?

Not sure if edlebrock is any diff but my manual said to torque to only 10-15 ftlbs. Its the lower ones that need to be torqued to 23-25 I believe.

Upper to lower = 8-12 ft-lbs

Lower to head = 18-22 ft-lbs

Also, be sure to torque the lower in sequence, and repeat the pattern 4 or 5 times. The bolts will back out quite a bit during the first few times around.

Is it really necessary to take the upper off and retorque the lower after driving the car a bit?

Since taking the upper off only takes about 5 minutes, I'd do it just to be safe. My lower bolts barely backed out, if anything at all.

Yeah, and from what I remember the lower is 15-18..


AAHH straight from my tech article, which the specs came straight from the instructions..

The specs call for 15-18 ft-lbs of torque

Be carfull on the upper bolts. I guy i know got his car with an eddy intake on it and one of the eyes that the bolt goes through on the upper broke off. I search around and i guess thats a common problem with them.

I know my engine builder told me that the lower intake shouldn't be tightened more than 18lb otherwise it would actually start to pull the heads away from the block. Considering he's built Busch North series engines, it's advice I feel is pretty reliable. Don't know about the upper.

I would like to stress as the poster above has that the ears on the upper will break off if they are cranked down too much.

I've seen many say that this has happened to them.

If both surfaces are clean and the gasket is new you really don't have to use a lot of clamping force to get a good seal.

Sometimes very low tq values are not as accurate on tq wrenches as larger values.

I just snug them down until it feels right but if I had to guess at a tq value it would be about 12 to 15 lbs.


I check them a couple of times after several heat cycles to see if they are still good to go.

Yeah just like they said. Only hand tight, doesnt need to be that hard to make a seal. I think i tightend mine down to hard and the back drivers side ear broke off of mine. Gotta be gentle.

I just got one from a guy with a broken ear for $100. I'm going to have a buddy weld it back on this weekend. All you have to do is bolt everything togetor including the broken piece then weld it and then your set.
