You caught me looking at little-bitty solid cams for my 283 motor that I am going to try to make some day at 9.75 to 1 CR. or thereabouts so here goes if you want more low-end out of your Z- motor!!
An old Isky grind single pattern .481/256/212/ on a 110/110 lashed at .020.....timing 18-58...58-18, and it is symetrical.
An Erson solid cam, PN TQ20M, 270/220, .465”/.465”. Timing at .050” duration, IO=23/IC=67, EC=67/EO=23.
A really old Isky Hi Rev Solid, PN = E-4, (19-61 / 56-24) .... 260/?, 114/122, .410" gross lift and lash at .015.
In my last 327 I had a Crane F218/2933-12 lobe.
.440 / 218 @ .050 on a 112 .Great idle , pulled 17 in vac at idle .. dead under 2000 but went nuts between 4000 and 6000 RPM....Mainly due to that 112..Grind it on a 108 and it would be great....
UDHarold's grinds like
256/225, 110/?, .454" gross lift.
264/232, 110/?, .470" gross lift.
272/238, 110/?, 485" gross lift.
CC 270S solid...
One of my favorite solids but old-fashioned today, the great little old GM, stock, Duntov -097 solid Vette cam....
It came stock in 283's and up to the 360hp/327 F.I. motor back in the day.....
Please note these little-bitty older cams will really tune your motor down so that it will produce a lot more low and midrange torque if your compression isn't too high to use them.. AND they are NOT race cams by NO Stretch!!!!!
I can't help you if you are still running a true 11 to 1 CR. Z-28 motor so you are on your own there, b/c any attempt tp tune them down will probably lead to more detonation problems b/c of a faster closing of the intake valve trapping more charge -- sorta deal..
