1.7 rockers installed feels like less bottom end

canukracer · 12-09-2003, 01:30 PM

stock 5.0 runs good no lifter noise is this normal to have less bottom end, could it be just in my head?

/did 0 lash then bolt turned down 3/4 turn.

I just had the same problems, made a change and lost bottom. I think in your case that you rockers are too tight. I use the roll between the finger method.

If you tighten your intake side down 3/4 of a turn, then only do your exhaust side 1/4. good tip that was passed onto me a long time ago.

I'm installing 1.7 roller rockers right now.
0 lash means the rocker is just tight enough so it will not rock, Right?
Also I went to 0 lash gave it 1/2 turn and they would push down on the valve opening it a bit, is this to tight

2nd are the lifters supposed to compress a little, because mine are not.
Thanks
