I have a dead cylinder (#3), and #2 seems to cut in and out. I have a detailed account in the technical Q & A but basicly I have spark (most of the ignition is new), 160 psi compression, great leak down, fuel (plug is black), valve springs are unbroken, cam lift is equal to other cylinders when measured @ pushrod w/no rocker arm, exhaust port and manifold (stock) show no discoloration to indicate reversion. The miss seemed to start after I lost the sea water pump on that motor, but the water temp gauge never went above 210, so it may be unrelated.
Oh yeah, its a 97 454 mag carbeurated all stock, 200 hrs.
I am open to any and all suggestions!!

Yup, new plugs, wires, caps, rotors, f. filters, swapped coils and hall effect switches from the other motor. No effect.
All the details are in the technical Q&A.
Thanks Biggus!

Crazy horse, you have the answer!!!!
Tonight I'm going to swap #1 and #3 valve springs to see if the skip follows.
