1995-1997 1UZFE LS400 engine (1996-1997 SC400) 232 degrees intake duration (6 BTDC, 46 ABDC) Intake lift increases over previous design but likely no more than .309"/7.85mm, I could not find specifics only that it was increased. Exhaust lift and duration is the same as earlier design. 229 degrees exhaust duration (41 BBDC, 3 ATDC)

"The most effective would seem to be changing the standard exhaust cam for an exhaust cam with revised opening of 55 degrees BBDC (Before Bottom Dead Centre) and closing of 18 ATDC (After Top Dead Centre) (standard exhaust is 46 BBDC and 3 ATDC). This changed exhaust cam with the standard intake increased the horsepower from 260 to 300 !! (modelled on Dyno2000)."
"I was measuring some things on my 1UZ and I also measured the max lift for the stock 1UZ cams (from a crown engine):
Intake: 6.75mm Exhaust: 7.00mm"
And I also need where the measurement is taken ie "seat to seat" or "0.050"
