what should i torque my rocker arms to in my 305 tbi chevy?

Question

my haynes manual has the specifications for the 7.4L and the 4.3L but not the 5.0L, any help would be very helpful. i haven't been able to find out through google so i came here.

Answer 1

Basically do this: Find TDC on # 1 cyl. Tighten the rocker till the pushrod has a little play in it and you can basially spin it with your fingers yet is almost touching the rocker. then turn it another 1/2 turn which should put it down about .075. Now do the rest of the same, but it is imprtant to do this in the firing order of the engine. Most mechanics don't, unless they really know thier stuff. So it would be 1,8,4,3,6,5,7,2. Look at the book, it will be more detailed than what I am giving you. Mechanical lifters are set differently, so make sure you read the section that applies to your application. Easy as pie. See ya' at the race track!

Answer 2

i own a repair shop,and the reason you couldn't find it,,is because it don't exist,,you have to adjust the valves on that one,,the valve lash as its called has to be set with the piston up on tdc,,the manual tells about it in there it also tells you where to set the pulley at and what valves to set while that piston is up,,if you tighten these all the way down it wont even run,,the procedure is in the book on how to do this,go to the section where it says adjusting valve lash,,it will explain it good,,i hope this help,s.

Answer 3

They aren't torqued. you set the lash..in your Haynes manual look up valve settings or under head / valve replacement it will have a chart like I or intake 1,4,5,7, E or exhast 13,6,8 @ tdc rotate 180deg. and the rest
dont ust the order I listed.
If you tigten the valves all the way down you will hit the pistons and bend valves

Answer 4

You don't need a torque specification. Just use common sense. Tighten it very tightly but not enough to break anything.
