L88 cam in L78?

[VintageMusclecar]

If I may chime in;

FWIW, the 2 smallest solid grinds Crane makes work extremely well on mild BBC applications.

238*-248* @ .050
304*-314* adv. dur

.022-.022 lash

P/N: 134781
3800-7000 rpm

110* LSA
.567-.590 lift (gross)

The first of these 2 cams provides a nice flat power curve and a fairly mild idle. The 2nd cam is a bit "peaky" with a noticeable midrange charge, and a somewhat more noticeable idle.

I ran cam #2 in a well-worn LS6 "clone" motor (it did have a Dart intake and 2" Hooker headers) in my `67 Chevelle years ago, and it's 1 of the best street/strip cams I've ever used. Blowing through a "way-too-small" 2 1/2" exhaust, with only a 2500 converter and 4.10 gears, this was an easy low-12-high-11 second combination. In a 396 with OEM manifolds, I'd opt for the smaller cam.

Re: The advertised rpm ranges Crane recommends... I've found that these cams often come in sooner than Crane advises; perhaps this is an attempt on Crane's part to keep people from "over-camming" their engines, I don't know.

Just throwing my .02 in. [img]/ubbthreads/images/graemlins/beers.gif[/img]
