I have a brand new hyd. cam, lifters and springs for a small block Olds motor. I ordered the parts last winter , but when I started the build , I went in another direction . These parts are BRAND NEW. The parts are above stock in performance. I have all the paperwork . Paid $450.00 for it all , I will take Much less, just to move them on ...... Call with any questions 309-370-3480 Mark The Grind # is JM 18/20 Extreme, Valve lift is 488 , Duration is 292 . Gross cam lift is 305 , Duration @.050 is 218 , and lobe centers are 112 .

 

Here's a thought....maybe list the cam specs or atleast a part number.

 

Yes Dave , You are right .... Thanks ....

 

The JM 18-20 is a dual pattern cam from Engle that Mondello has sold for decades.

JM-18-200.4880.496260°/266°216°226°112°1000-5000

I have this cam in the 468 cid BBO on my p/u with Rhodes lifters & a performer intake. It put 440 ft lbs TQ to the ground @ 3800 rpm on the chassis dyno .

Very nice cam for towing or in a heavy vehicle with highway gears.

You refer to your's as a JM 18/20 EXTREME with different specs. I have never head of this cam and I do not see it in their catolugue.
