Prototype Purchase Program

We have developed and got a couple of ours running, but we need owners to prototype and eval new systems (currently Gen2 EFI),  We do this to work out the fit, look, installation and operation of our products. We have a limited number of evals because we still have to sell these to make money to keep the doors open.  All current systems are DIS only.  You must have the mechanical ability to install and a laptop and some tuning skills (or willing to learn).


  • LM 110 Manual
  • EM 80-95HP Auto
  • LM 140 4 TBI
  • LM 140 3.0/3.1

You will at a price less than our wholesaler pays… in exchange for:





You will need a Wide band O2 sensor (LC1/LC2 or similiar) NBo2 supplied with kit.

After the Eval system is over, Clarks Corvair will be the only seller of our products.  You must have good mechanical skills, laptop and light tuning skills.  You will be purchasing this system, so it will be yours, but we request that you help up perfect the product in exchange.
