Pma's 409

Hi Folks,

My wife did not like riding in my 64 Vette (too small and fast for her) but she likes big cars. With that, for her birthday this year, I bought her a 1964 Impala SS 409 Dual Quad 425 HP -- the Beach Boys car "4 speed, dual quad, positraction, 409"!! Now the plan is to do the local car show circuit as a "his and hers" pair -- when they start having shows again after this virus scare.

I have always had Vettes, but never a big Impala, so this will be a learning experience for us both. I am sure that the knowledge base of the forum members is great!

Welcome to the Team Marc!!!

Tuning dual carbs is a pain, but it looks cool. I used this tool I bought to tune Webers and Solex carbs on Jags and VW s..

To run it on a an Carter AFB carb (like you have on a 409, or possibly an AVS if they are using the newer Edelbrock carbs) I used a chunk of styrofoam to cover the cabb and allow the meter to fit on the top.

The meter is just an Anemometer (a little windmill used by weather men to measure wind speed in a Hurricane for TV viewers). You need that and a vacuum gauge to covert two four barrels into one eight barrel carb, with equal air flow to each cylinder.

You have to balance fuel supply (idle adjust screw with the vacuum gauge) and air flow (adjusting throttle blade angle) with the anemometer.

Surely a VERY nice car.

Actually, the Beach Boys song was about a 1962 version (409 hp), but '64 is close enough.

Here's an article you may find interesting:

ENJOY!
