the moment of truth

ok...this has sorta been covered a bit but not really...i really want to do this...i want to flatten out the area above the 2nd and 5th intake
then have a metal plate i can bolt on...have some tubes welded to the plates which will go to a box...the inside of the box can be shaped for smooth flow...but i want to be able to attach a carb in the center of the engine..and also have the option to go from any carb. this way would be the easiest i think cause the middle doesnt have to be taken out...i would just make a block off plate with a single tube sticking out of it for my hydrogen setup to connect to...does any one forsee any problems with haveing a setup like this...anything like sluggishness and low or high speeds...what would compliment a setup like this? just a few thoughts and comments would be appreciated...i really want to upgrade but not something that will take a long timei want to make it...then all i gotta do is file grind dril..tap..whatever...attach..basically a project that wont take too long at all. how long has it taken u guys to install a new head? or even just take it off and put it back on?

The design looks good on the face of it, but I'd worried that you would have to make it too tall and you wouldn't have the hood clearance. you would probably get decent distribution (especially if you put a restrictor in the middle to divide the two halves of the log) and good torque since the tubes will be longer.

BUT, my first reaction to the idea is , since you will have to remove the head anyway to do the drilling and tapping, why not just go with the simpler and already proven approach of milling the log flat and bolting the carb right to it with a short spacer/adapter? Especially since others have already suffered throught he trial and error engineering.

Why not mill the head flat on top of the #2 and #5 cylinders...and mount 2 1Vs with a non progressive linkage? It wouldn't be that hard.

You are going to run into clearance issues. When I put the Offy on with Autolite 1100s (very short), I had to cut my airfilter in half because of clearance issues.

Except...maybe your car being more full sized then mine might have more room, but definitly check.

Other wise...looks like s solid idea.

Why not cut the holes in the side of the log? That will give you the neccesary clearance.

The additional intake volume and runner length will decrease the signal to the carbs and likely reduce low end torque and possibly create a bog. I agree with Slade that 2 carbs mounted on the runner may be a better option. I had a V-8 with a leaky Rochester Quadra Jet. Rather than rebuild, I put on a newly rebuilt Carter AFB on that I already had. It required a spacer adapter plate. But the spacer, as well as the larger carb created a low end bog. At higher rpm's the engine did pull a little better. But, given the limited breathing capacity of the I-6 in stock form, you may not realize much upper rpm benefit unless you work over the head entirely.

thank you all for your replys...i forgot to mention that hood clearance wont be an issue when i do this...cause before i do this i am custom making a hood for my car...there will be loads of clearance. i have thought of doing 2 single barrel carbs, but thiat would be a bit trickier to setup...although some of u will say its not that hard at all..but it would be really nice to choose whether i want to have a single, double or four barrel carb when i want it..a blocking plate between the midle is an excelent idea...wouldnt be too hard, just take the dremel and grind slots down both sides to hold it better and then epoxy it or something. At fist i was planning on doing it with the head still on..but thats asking for trouble..although i did grind the existing hole to allow for a smoother flow, just stuffed rags in the intake and used a vacuum...made sure it was really clean, and it was...but trying to stuff a rag down to the 2nd and 5thi would be a bad idea...so i will get a used head and work on that...i will most definitely do some porting though. this will be a project for next month...since the hood is first, but a head start on ideas is definitely a good idea. i heard that spacers are good for improved throttle response though i suppose it depends on the application.

actually...just time...and a little bit more experience..it was about 1:00 in the morning when i did that so i wanted to do it quick....but to appease u I will replace it with a better version later on.

is this better? then also do the log dividers with the pcv port as well.
