Barely used. Comes with carb stud kit installed on the intake, assume the stock calibration for electric choke on the carb.
$250obo each + shipping or I'll do $450 + shipping for the pair.
The carb cheater isn't in the same hemisphere as the sniper or this new Edelbrock system.
You can read my rants in other posts, carb cheater is a vacuum leak that for some reason people think is useful instead of doing the actual work of tuning fuel delivery.
Just another tool in the toolbox, the HV pump will give more hot idle psi without having to stack washers in the spring that will affect the psi at other rpm. A person may or may not want that (nobody needs 80psi going down the road)
