80LS1T Posted November 24, 2002 Share Posted November 24, 2002 Ok I have a 93' LT1 and I want to convert the old Opti Spark to the newer Opti Spark unit. I have the timing cover and new opti spark distributor. What else do I need? Thanks, Guy Quote Link to comment Share on other sites More sharing options...
Mudge Posted November 24, 2002 Share Posted November 24, 2002 Intake elbow or intake elbow hack job yourself, this is where the vacuum lines go. Need the vacuum lines, and new 95+ wiring harness, this plugs into your stock harness, the connector is longer than the 92-94 setup, alternative is hacking up the Opti, which could cause issues that RTV may not keep at bay. Other than that, you just need some gaskets, and a way to pull the LT1 hub, after removing the balancer. If you haven't done this before, well unfortunately SBC pullers dont work on the LT1. I used a 1/2" longer crank bolt to do most of the work, along with the regular puller, here is some info: http://www.go-fast.org/z28/damper.html The thread info for the bolt is also listed in the above URL, which I picked up at Napa Quote Link to comment Share on other sites More sharing options...
Mike C Posted November 24, 2002 Share Posted November 24, 2002 Doesn't it also require a cam with a longer dowel? Quote Link to comment Share on other sites More sharing options...
