Trickflow 2000 with 1.7 rockers. whats the lift?

[fiveoho]

.499/.510 i believe with factory 1.6's. what would it be with 1.7's?

also, would springs that have 130 pounds on the seat , claimed .540 lift, be sufficent on a set of iron gt40's with this cam and 1.7's?


thanks guys

seems to me it would be:

.499*.17/.16 = .5301875
.510*.17/.16 = .5418750

Want to know your lift values after a roller rocker change?

Take your current lift numbers and divide it by your current roller rocker ratio. You then get the lift numbers at the lobe. Take your lift number at the lobe and multiply it by the new roller rocker ratio.

Example:

.500" divided by stock 1.6 Roller Rockers = .313"
.313" x by new 1.7 Roller Rockers = .532"

So take the Trickflow Stage 1 camshaft:

.499"/.510" with 1.6 rockers.

.499/1.6 = .311875 x 1.7 = .530" (new intake lift)

.510/1.6 = .31875 x 1.7 = .542" (new exhaust lift)

cool. thanks guys.

it true that 1.7's are harder on the springs more so than 1.6's
