Ignition is my prime concern here as the LT1 uses the illustrious optispark. I have access to this engine dirt ass cheap. Plan is to give it a stock rebuild and throw it in my truck, hopefully knock the compression ratio down around 10:1 flat. The appeal is the aluminum heads and the intake that accepts normal injectors that are easily upsized when the Whipple goes on, which the aluminum heads will again better facilitate than my Vortec irons.
