Re: k-grind 1800 72

posted by  someone claiming to be Camster on  Wed Nov 29 19:14 CST 2000 [RELATED]

Hi folks --

There have been more than one K grind cam; Volvo and ipd have each produced (at least) one. The ipd K cam hasn't been around for about 20 years.

I hope this is still accurate -- the spec sheet I have indicates:

Volvo K: 277 degrees' duration/.420" gross lift.

ipd K: 259/.429"

Volvo's cams didn't really follow anything too logical; that is, they didn't always get wilder as the letters proceeded 'up' the alphabet. Well, sort of, but not completely. For example, there was a G cam that offered 308 degrees and .457" gross lift; more radical than a K.

In case this i still interesting:

Isky's VV71: 268/.441"

Isky's VV61: 256/.425"

... and their Z309 (108): 314/.538" !! Yeee-HAW!

Isky does follow an alpha-numeric logic, from their VV61 up to the VV111, then makes a break and switches over to Z prefixes. Delong made cams that went from reasonably tame to well beyond anything reasonable in terms of duration and lift (312/.520"), as did Crane (300/.540").

There are companies out there who never stopped developing and improving on cams for the pushrod Volvos and there's a whole lot more useful and really cool stuff available now than there was in years past. Just boils down to 'how fast can you afford to go?'

Anyway, hope this is of interest.
