383 Big Block, Hydraulic roller cam, Sniper EFI, Sniper Distributor, MSD 6EFI box. At first I wasn't running the timing control and was running a regular MSD Distributor but I'm now running the Sniper distributor and having the sniper control the timing. I also run a A518 trans with Compushift Mini controller. I went Sniper because I wanted it to look "stock" to the layman. oh I also run an electric fan and electric water pump now too.
