soo i just finished building my first motor, a 1973 sbc 400 . 60 over to a 410. i put it in a 91 camaro rs. now i need to know what to do now. i got it running and broke the cam in but had to shut it off quickly cuz the rockers started coming loose. i need to know the procedure for this action of tighting them down again and any other steps i should take to do to the motor. anything will be appreciated thanks

 

I'm assuming your talking about valve adjustment and setting the lash...correct me if I'm wrong. Here's a good read for the process

I adjusted the first 8 at #1 TDC, and the other 8 at #6 TDC, they actually didn't make a sound..
Do you have the rockers with the locks, or no?

 

i have full roller harland sharp rockers that have the black nuts with set screws in the middle? idk if thats what your talking about and id rather do the adjustment while running not when its off. to hard to turn now with motor all hooked up, so if you have instructions for that thatd be helpful

 

What size cam

Screw in or press in studs, could be a source of the sound youre hearing

 

screw in studs and cam is .504 .525 lift .234 duration

 

Make sure they are torqued (50 lbs outghta do it) Then recheck adj. Make sure rollers are in good shape on the rocker arms, rocker body etc isnt hitting the retainer, etc, little stuff. Check for broken springs (far fetched but you never know). Youll find it.
