So the travel was 10.5?

Sorry should measure properly, That was without the cup and a snapring, here it is without spring full down upto snapring. So it's 6mm, so perhaps v6 didn't get the lsx updated lifters? I rechecked and both are same

well that's what I've seen as well, the old design used throughout.

yeh must have had some old stock to use up

The latest designs have come a long way, so it's a great upgrade without even needing to go aftermarket.

We put the ls7 disk style lifters in the last build they changed the tune big time over stock v6 lifters. We actually got all of the duration of the cam idle was choppy as shit and air fuels were rich down low was a big difference

We did change timing sets too maybe it shifted the cam a little too but you wouldn't think that would chop it up so much https://youtu.be/Ovbyn-Iak04

Nice stuff, so because of the shorter travel and smaller preload do you then need shorter pushrods?

Normally yes, mine were slightly shorter than stock after everything was done.

Well i put VT Cam and lifters in, all quiet again and running well, checked oil pump in front cover and chain play and all looks good and within spec, hopefully get a few more k's now out of it.
