Intake torque?

[Bill Monk]

Ma Mopar says 40 ft lbs on the intake bolts but I'm pretty sure that was for a cast iron intake. Edlebrock recommends 25. I have an original 69 1/2 edlebrock 6 bbl intake. What do you guys recommend on the torque for this piece? I can't find anything from mopar on what they torqued the aluminum piece at.

35tflbs using a grade 8 bolt and a washer under the bolt head to protect the alum.

I thought it was 35 anyway..... even, snug & using washers.... it's the aluminum HEADS I'd worry about for over-torqueing an intake, not the intake itself.

Make sure you have plenty of thread engagement & never seize on threads for alum heads.

A hardened AN type washer, not a soft, thin box store washer.
