Final answer on LS7 preload please
Final answer on LS7 preload please I know its beat to death, but there is so much debate on LS7 lifter preload. I would like to hear from a legit engine builder or vendor please. I measured my push rods today.
Length checker is 6.8" closed
I turned it out 12 times to match my 7.4 push rods.
Closed it down two turns. (7.30") perfect
10 turns to close = .500 6.8+.500=7.300 .100 preload is 7.400
Is .100 good for a street car? I drive it on the weekends and track it about 3 times a year. I've read .050-.080-.100, is there no real answer?
