Was this a hydraulic roller where you see the gains/losses?mt-engines wrote: ↑Wed Nov 18, 2020 4:16 pm I've seen valve lash change rpm more so than specifically changing intake centerline.
I am using one of Mike's cams. nothing radical276/280 adv 228/232 @ 50 576/576 110 lsa installed at 107icl exhaust 113 icl. I just degreed it where the card said to, and set the lash 1 turn past zero lash with the delphi ls replacement lifters. Given the fact that I want this engine to be as strong as possible from idle to 6000 would looser or tighter lash help? new 385 sbc, afr 195 street ports and shaft rockers from scorpion racing. as is it started right up, is very quiet, got oil up top almost instantly when priming. I was actually surprised at how quiet it was at idle for a first start of a new mill.
Think going looser would help? I read a lot of conflicting info on these lifters being used in the gen 1 880 roller block. many lash at 1?2 turn past zero lash, yet others have went 1.25 turns past zero. and still others have said set preload for them the same as you would in the ls block. if running a little looser would help it rev easier off of idle, or tighter I would be all for that.
