OK I will be doing the swap from my 4BBL to the 6-Pack on my 340 Dart..........anything I should know that might save me some time and effort? I want to know all the little tricks to make this as smooth as possible.........and thanks in advance!

OK, we'll start with the obvious. Do you have a COMPLETE install kit? Fuel lines..coil bracket...throttle cable mount.... intake manifold gaskets? Is it a new set-up, such as the packages sold by Glendora or Mancini's? If not, be prepared for some re-building. And get ready for some never-ending adjusting and fiddling.

I just bought the ProMax center carb metering block and the end carb metering plates that accept replaceable jets, along with the billet rear carb base so you can adjust the idle without pulling off the center carb. I haven't installed these pieces yet, but they come highly recommended as a cure for the ever-present stumble and flat spot factory 6 bbl's are born with. As for adjusting, I recommended removing the plugs on the end carb base plates and crank out the idle screws about a 1/2 a turn (bet you didn't know they were adjustable, did ya? ) and this will improve idle quality. As for jetting and power valves, go with the stock pieces and see where your at.

And finally here's links for tips:

Before I pulled my car off the road I had the carbs kind'a dialed in and wow...when those end carbs open up you better be pointed where you want to end up! I can't wait until I have the new combo together.

Good luck with your swap. Aside from the basic skills needed to pull the manifold (drain coolant, mark plug wires & vacumn hoses, CLEAN all mating surfaces for gaskets, etc...) it's a straight forward job that can be knocked out in an afternoon. And let's not forget the WOW-factor when you pop the hood...8)

Here's that engines bigger brother I just delivered a few weeks ago. 505" RB with a 6bbl. Carbs were brand new, and I used the same promax jet plates and metering block (not shown in this pic...they were backordered at this point...lol. I have a video, but I need someone to host it for me, and I have to send it to them from work...Dial up will take forever...lol.

Like was said, have the full kit. you need the coil bracket, fuel line package, linkage set, and vaccum lines handy. With all the stuff new, it took me about an hour to install the carbs after mods. Start with the center carb fuel line, then rear, then front, and dont tighten anything until they are all started a few threads at least. They should be able to be threaded together by hand with some "massaging". Also, the outboard linkage should be re-adjusted after base idle is set. They should slide into the outboard carb levers with no preloading...so they are totally relaxed when the throttle is closed. Take you time!

It`s a 70 440 HP block .040 over with the 4.15 rods and KB flat pistons. Displacement is 495.6 c.i.. The heads are MP aluminum mildly ported ,2" TTI`s, solid 520/540-286/292 cam with roller rockers, MP dist. w/MSD. The intake is the Eddie 2475 opened to match the heads and the carbs have been rejetted. The carbs are still actuated via vacuum and work beautifully on the street. If I can find my old Direct Connection book I`ll post the section on what Mopar called "one of the best" carburetor set-ups to use for all around performance, the six pack.
 
John from Queens, that is the most beautiful build, and each of you have awesome looking builds, but I had to comment on John's 360, I admire that very much. I hope mine will be that nice, someday! My 68 cuda has a long way to go before it gets where yours is. If I could ask, where did you score the fab'd valve covers? Are they Diamondbacks? I can't wait to get to the next phase of my build, but I am still trying to complete the right basics. Gotta do it right. Also, what intake is that? It looks taller than the mopar one, am I mistaken? What brand is it? That can't fit under the hood, what scoop did you choose for your cuda?
