Re: Elderbrock AVS carb
apparently the first three digits are the julian day and the last is the last digit of the year. (guess it's up to you to know the decade).

Re: Elderbrock AVS carb
I run an AVS2 on the 366 in my big truck, I'd recommend it for sure, the annular boosters really do help throttle response under normal driving conditions, even in such a heavy truck. Definitely get the insulating gasket, I have one and occasionally still have the boiled dry fuel bowl issue, a lot less when I run better gas though.

Re: Elderbrock AVS carb
I have a used, rebuilt 1406 on my crate ZZ4 and for the past 15K it has never failed me. Stock fuel pump no reg and never had a heat spacer. And in my 65 mustang that runs hot under the hood with my fresh 289 built radical I have a new 1405 box stock without the heat spacer and again a stock fuel pump. Never hard to start. In fact I never have run the heat spacer on any of my cars and always run a stock pump, guess I am missing something here for the past 50 years

As for the pump, it's always been the same for me. Stock with around 5 psi, I assume.

Re: Elderbrock AVS carb
I needed a regulator for my 1406
Pump was putting out over 9psi I might be mistaken, but q-jets only need like 4 psi.

Re: Elderbrock AVS carb
I stuck a guage fitting inline just before my carb, the stock pump on my truck pushes 4.5-5 psi consistently.
