Vixen isn't happy unless she's right around 1000, give or take. She'll idle lower, but she's not crazy about it. I've messed with her every which way but that 1000 mark or 50 or so under is the magic spot. Course bein a slant 6 might make her a little different, too.

Is a cam on a 106 LSA not the next best thing to an.....:eek: Feel free to post up some sound clips of whatever you have, as long as the cam is on a 106 lobe separation angle. If you want to give additional details of the engine by all means do so. IMO there’s nothing better than the chop of a “106” :thumbsup:

What’s the specs of this cam?
 
12..... is this your old cam?

Be interesting to know what the lobe taper is on it(and/or how much crown the lifters have).

It looks like the wear pattern is off the edge on the base circle.

Might just be how it looks in the pic.

It’s out of my sons 78 360 that we’re now rebuilding. Just a “prop cam” :eek: for the picture,

EAR **** !!!
 
I have a solid roller I tried to run in my 400 small block (Chevy, sorry) but with the long rods from a 350, the rods hit the cam in a couple spots, cause it wasn't a small base circle. It is a brand new CamDynamics, ground on a 104 LSA. I bet it would have a nasty lope, with 270° at .050 .
The old 312/.590 purple shaft that I had in my 440 is supposed to be ground on a 106 too. I don't remember it having as much chop as 12many's van. IF I have any sound of it, it would be on a VHS tape, lol.

The secret to LSA is the correct one for the engine.
D. Vizard lists lots of cams in his SB Chev book. From 302 up to 434 [ stroker ] . Even the mildest engine, Street & Tow gets a tight 104 LSA for the 434 & up to 110 for the 302. What gets changed is the duration, 199 @ 050. Same 199 @ 050 duration for 302 through to 434; LSA is the only thing that changes, decreases with cu in.

From all the reading I've done, I agree with his assessments, BUT there have been a lot of otherwise "mismatched" camshafts that have run damn good.
 
RRR,
Quite agree. How many times do we read on this forum [ & others ] comments like the new cam runs 'great', 'more power', 'spins the tyres' etc.
Of course it runs great, right because it has to be better than the old cam!!!
One sees these subjective comments all the time, but rarely is their an objective before & after dyno comparison.
DV derives the LSA from his cam program, & the 128 rule is a loose derivation of it that allows the engine builder to be better informed selecting the LSA...rather than just taking a stab at a cam on a catalog page. While 128 was for SB Chevs, I read somewhere that DV says it is also good in general for parallel valve heads. Certainly better than just having a guess...
106 has become 'popular', but I'll bet some of the smaller engines might want wider LSA & the bigger engines less LSA.

Is it a program, running the maths? or simply a compiled look up table based on previously recorded data?
I remember the early days of this, and how that "LSA finder" went through various permutations
(and inaccuracies) until it landed on being in the ball park for virtually SB only.
Considering it's based on piles of cam testing data for a SB Chev, you can understand why it's only somewhat applicable to such an engine, or a close variation..
