Lobe Lift:

Intake 0.0726-0.736 mm (0.283-0.290 inch)

Exhaust 0.0741-0.0751 mm (0.292-0.296 inch)

I gotta say, when I saw those specs., I was thinking "WoW" now there's some mfg. tolerances.

Split the difference, call it .286 intake and .294 exhaust, works out to .429 and .441 with a 1.5 ratio.

Here's what I got when I looked it up for a '98.

Lobe Lift (Exhaust) (L35) 7.20-7.30 mm (0.283-0.287 inch)

Lobe Lift (Exhaust) (LF6) 6.54-6.64 mm (0.257-0.261 inch)

Lobe Lift (Intake) (L35) 6.97-7.07 mm (0.275-0.278 inch)

Lobe Lift (Intake) (LF6) 6.76-6.86 mm (0.266-0.270 inch)


Multiply by rocker ratio to acheive total lift.
