Hello all,new to this forum,in australia need help with misfire with my LT1 chev.
Quick run down on what I'm running--1996-97 LT1 series 3,

engine fully rebuilt and balanced,comp cam 230-236@.050,
1.6 roller rockers,ported heads,bigger valves,comp valve springs,
bbk 58mm Tb,haltec ecu,30lb injectors

Car on dyno yesterday runs fine,up until 5000rpm when the misfire starts,
replaced coil
new leads and checked resistance
changed spark plugs (bcp6e)with 0.8m gap,even tried 0.7m still misfired
this engine I brought to suit rebuild and dont know if this opti-spark
is the right one,at this stage pointing the finger towards the opticile sensor inside the opti-spark.

And of course nobody in Australia has one.Can anyone help,with where I could purchase the opticile sensor on its own,at a reasonable price.

Hey LT1 Aussie, I'm also on the other other side of the world and I've delt with Jasson, He offers very good prices, but I don't think you can get the optical sensor seperate from anywhere, you need the full assembly PN 1104032.
His number is: 877 726 8295, he works here: http://www.samtaylor.com/en_US/
