Re: WEBER vs HOLLEY
I was running quad 44mm idf webers on my 347. From memory, 55 idle jets, 145 main jets, 36mm chokes. I feel my 44mm webers where a bit of a mis match for my 248@.50 cam. I should have gone with 48mm ida's, would have suited the rpm of the cam better.
There is lots of talk concerning tunning of webers and hp output v's 4 barrel.
Well I can tell you first hand that the rumours about they go out of tune easily is bullshit and 4 barrel will give you more top end but less mid to low grunt is true.
If they are set up (syncronised) properly you will never have a problem . Like any carb set up it will behave differently in cold and hot weather , its more noticable with webers than a 4 barrel.
I have both dyno sheets for webers v's four barrel , the only difference being the webers had a 248@.050 solid cam and the four barrel a 228@.050 solid cam.
As previously posted the cost is very high and is slightly cheaper than injection.
It will probably cost you about $1000 for manifold, $700 per carb, linkages $150 , labour.......hate to think.
If you have the money, it will be money very well spent. The torque and low down drivability you get from the things is unsurpassed. They will smooth out the lumpiness in you cam at idle and allow you to cruise around at very low revs without it bucking like a horse.
Its a big out lay of cash but it is simply awsome. I love them but cant afford to have them anymore.
