    20-185 is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Look No Further; This Is The Accessory Kit For You Our project is a 1980 Camaro / LS3 E-Rod swap. The 20-185 Holley kit is excellent. Great, tight-but-not-too-tight location of accessories. No clearance problems anywhere, with one minor exception; the vapor purge solenoid could no longer be mounted on the front of the engine where Chevy says to mount it. No biggie; it looks better mounted on the firewall anyway. We didn't have to use a remote power steering reservoir; we did have a custom high-pressure hose made locally to go between pump and steering gearbox. A steam port inlet on the back of the water pump enabled us to have super-clean, nearly-invisible routing of the steam tube from each head. The instructions are very high quality (and light years better than their carburetor rebuild instructions). Based on several phone calls (some for how-to, and one for a minor issue with the kit), Holley's customer service is the best I've dealt with. They ALWAYS answer my emails. I would use Holley for the quality of their customer service alone, though it had nothing to do with why I initially chose this kit.

    What thermostat does this use? I want to replace the 190° thermostat supplied with the kit. I purchased an ls3 thermostat which was too small.

    Asked by: Thevtecnician
    The Holley 510-20-185 uses a standard LS1 thermostat.

    Will this fit on a LQ4 block with L92 heads and a LS3 intake manifold going into a 83-88 Monte Carlo SS?

    Asked by: MechMan
    Yes, this kit should work in your application, it may depend on the engine swap kit you are using.
