im swaping my intake can any one tell me the torque spects and order ty
oh yeah the engine is a 350
Chiltons says 30 lb*ft on the bolts.
The pattern starts with the center pair of bolts on each side - do the rear one of that pair, then the rear one of that pair on the other side. Next the front two of the center pairs, and keep working in a spiral pattern outwards. Hope that makes sense.
I also usually do it in two stages just to make sure everything is torqued evenly and is flat - one pass at 15 lb*ft, then a second at 30.
cool i thought it was somthing like that but wasent sure ty
Hey, I thought I hear sometime in the past you torque the aftermarket aluminum intakes less than the factory cast because the pressure could crack it??
could someone check this i am putting on an aftermarket one like a performer type
Intake doesn't matter....if it's an SBC then the torque specs are 30 lbs./ft.
Torque in 2 or 3 stages, then check every week cause heat/cold cycles will relax the gasket.
What about the 4 center bolts? How do you meassure their torque?
It's near impossible to get to them with anything else than a standard forkwrench.
I recently installed a Edelbrock Performer, but I tightened the bolts to the point where they felt tight, but not overlytight. Offcourse I did tighten them in the order they should be, starting with the center ones.
