1968FormulaS340
Well-Known Member
This is what I am replacing. It worked very well and sounded great. I have the compression (11+), heads, Victor 340 intake, Holley 800 dp, 4 speed, 3.91 gears, TTI 2.5" exhaust with "X" pipe and 26" tire so support it.
But I also have the 340 exhaust manifolds back on (but we can ignore this for a moment because headers may be in the car's future.)
Crower Street Roller (Solid) This is the 1989 version which is not the same as the one offered under the same grind number now. These are all the specs I have.
#31406 (lobe center 112, Adv dur 290 294, lift .550 .555, RPM range 3200 to 7200)
This is what I just ordered as a replacement.
Advertised Duration (Int/Exh): 273/279
Duration @ .050 (Int/Exh): 243/249
Gross Valve Lift (Int/Exh): .578/.585
LSA/ICL: 110/106
Valve Lash (Int/Exh): 016/016
RPM Range: 2800-6800
