    AVS 2 650 carb sufficient?

    I ran 650 AVS 2 on my stock '69 340 years back. Had to increase jet size and put bigger accelerator pump nozzle in. After that it worked great.

    Edelbrock LD340 WTH?!?!?

    I run a LD340 on my small block stroker but I bought that manifold decades back when they were cheap. Wanted to go with RPM intake when I built stroker but Shady Dell said wouldn't see any improvement. Ppl been posting up a lot of newer Edelbrock castings are sloppy these days.

    IMMEDIATE RESULTS After Swapping Project Marsha to a Edelbrock AVS 2 Carburetor!

    I ran an Edelbrock 650 AVS when I had my stock 340 in my car. Had to jet it up fool around with secondary air door spring ect. Once I got it tuned was really happy with it great performance. I drained the fuel out of it when I pulled the 340 and its sitting in a box now.

    1968 GTS 340 with Carter AVS 4966S

    That thick gasket will help with fuel percolation / fuel boil over which happens with todays fuels.

    Help from experts wanted.

    Pretty sure Performer has the smaller ports like 318 heads. Performer RPM and RPM Air Gap have the 340 360 ports. Dual plane RPM gonna help low end torque compared to sit gle plane. And RPM not giving up much up top compared to Torquer on a mild engine.

    Rich idle, would this help?

    I had to open my secondaries a bit to get rid of my rich idle problem. This was on a new out of the box Holly 750 double pumper. Brian at Indio Motor Machines who had my cam ground told me to do so. Works great. Just open it up enough to lean it out not too much.

    LD340 intake

    Fuel is formulated differently in different parts of the country. Hear in Maryland percolation is very problematic. I say block off heat and get the eddie heat insulator gasket and do it right the first time instead of mickey mousing around with it....

    LD340 intake

    Do it right and get one of these: http://www.summitracing.com/parts/edl-9266 Use some small pieces of 20 gauge sheet metal and block off those heat cross overs.

    Hard cold start- lack of fuel- UPDATED

    Today fuel evaporates causing the bowl to be empty the next day. They took something out of the fuel to prevent this because modern fuel injected cars don't need it. Yes your carb could be leaking but this will happen on a carb that does not leak. Fuel percolation is a common problem and has...

    Edelbrock 1405 carb way to lean

    The eddie carbs tend to run real lean out of the box at least that is my experience. I ran an Eddie 650 AVS on my stock 340 when it was in my car and once I jetted that carb up and put bigger excellerator nozzles on it it ran great.

    edelbrock metering rod sizes

    Like said above the owners manual should tell you what jet/rod combo to run to get it richer in any one area of the power band. Some times just switch rods won't do it.

    leaking fuel sending unit

    A lot of times the ring goes off center if they knock it around with a hammer and screw driver to tighten it. I bought one of these and they work great for getting the ring tight and on center: http://www.quantaproducts.com/prodinfo.asp?number=C-LRW No cheap but well worth it.

    Carter AFB/340 Tuning

    If it is a Carter AFB then you can use an Edelbrock tuning kit which comes with a book and an assortment of jets/rods/springs. If what you have is an AVS you will have to use the AFB/Edelbrock flat rod caps. If you run with heat blocked off on the intake you will need to run richer. If it is...
