L77 Cam Self Install

did u check pushrod length ? from the point the rocker was against the pushrod and valve with no play how many turns did the rocker bolt take to do up ? thats a simple way to check pre load

No I didn’t check pushrod length, Tightened them all just so you could move the sides of them then turned crank until each was not under pressure they all took a fair bit to tighten up and aligned themselves in the middle of the spring!
I guess I’ll know if something unusual happens on first start up then I can start with that.
This is how they sat before putting covers back on

if they were on the base circle with correct preload it should only take about 1 to 1 -1/2 turns on the rocker bolt to tighten it down for ls7 lifters ? without a tune it may be a little different when it stats up also depending on the cam u got

Okay so all back together first start all good then road test and feels like I have no breaks and the revs stay at like 2000rpm until I’m below 5kmph then they drop back to normal.
So Steve sent a tube file ready for my new VCM 532 cam but I reckon something isn’t right so I’ve done some logging while road testing hope he can sort it out must be something to do with tune.

Yes I got the ls7 lifters

btw she sound great

There’s the culprit your a bloody legend mate thank you! Just have to try remember we’re that goes now hopefully doesn’t require to much to come off. It’s funny cause i was looking at that hose earlier today when assembling the top engine but completely forgot

Wow lucky I didn’t go to far was not good without the brakes.
Had a look connects to rear of intake manifold, tight spot with everything back on
