Gearhead,
x2 on the videogames. I never took autoshop in hi school but at least we HAD one. I'd tell my other teachers I was gonna skip class to go to autoshop & use the distributor machine. I was getting A's so they'd say it was cool. Back then "cool" was getting good grades AND having a fast car you built YOURSELF. Today its about how much money you paid for your car. At least theres a few of us left.
ANYWAY
Jay here is a stock 292 (ok rebuilt by somebody so I ASSUME cam is stock), lobe lift and angles
The ** measurements I always take but they are on the shallow parts so I dont trust those numbers. the .050 .100 and .200 are the most trustworthy.
Intake #1
.006 16 btc**
.050 18 atc
.100 35 atc
.200 76 atc
.232 65BBC max**
.200 28 bbc
.100 11 abc
.050 28 abc
.006 66 abc**
.000 base (always make sure it goes back to .000)
Result-
190 duration at .050 (180-18+28)
156 duration at .100 (180-35+11)
113 LCI
Exhaust #1
.006 63 bbc**
.050 22 bbc
.100 5 bbc
.200 35 abc
.232 70 abc max**
.200 74 btc
.100 33 btc
.050 16 btc
.006 24 atc**
.001 base (yup, lost a mil somewhere, oh well- repeat test showed same numbers and came back to .000)
Result-
186 duration at .050 (180-16+22)
152 duration at .100 (180-33+5)
109 LCE
Engine was stamped F0106THH
So I'd call this one
190-186-111 LCI 113 LCE 109 ie 2 retarded
.232 x 1.75 = .406 lift, thats spec so seems very little wear
I had measured another 292 cam, same way, got
188-189-111 LCI=112 LCE=110 ie 1 retarded
154-152 duration at .100
.233 max intake
.227 max exhaust (a little wear)
I had also measured a stock 250 cam at
172-172-105 LCI=106 LCE=104 ie 1 retard
140-137 duration at .100
.221 max intake
.210 max exhaust
Spec is .222 lift on both
The 194 cam is supposed to be even smaller, I think I measured one but cant find it just now.
Typical is +/- a degree or so and a couple mils but thats good enough for me, its better than guessing!
