>Who on the list is running dual side draft carbs?
I ran them for many years.
>I am interested in they think it was money well spent and what kinda of performance they received as well as gas mileage increase? decrease? same?
Gas mileage increase??? HA!
Expect more power, but at the cost of mileage. The power gain on carbs is NEVER what is promised in their ads, but the dual sidedrafts are actually a carburator that works offroad. Sidehills, bouncy roads, and steep hills don't kill them like they do the Weber downdrafts. The carb is a PITA to set up properly. I fiddled with it for years before taking to a shop that specialized in building circle track cars. They put it on their computer and it ran like fuel injection from there on out. Do NOT get the Mikunis. I ran them, but they are out of production now. Parts are hard to get. Get the Weber DCOE dual sidedraft carbs instead.
>Did you go to a header at same time?
I initially bought a Hedman, it was crap, leaked, and fell apart. I then ran the Thorley and loved it. It was a good compliment to the increase on the intake side.
>Are you running the 1300 or upgrade to the 1600?
I ran it with the stock 1.3, with a 1.6, and with a 1.6 block with 1.3 head. Hard to compare the performance though since I didn't have the carb working to its best capability until I took it to that shop. At that point, I had a 1.6 block, 1.3 head with 1.6 valves and a port/polish.
>I am thinking about going to the 1.6 with header and then using some side drafts. Maybe a mild cam and a crane ignition system.
Cam is good. Save the money on the ignition system though. I've used both Jacobs and the MSD 6A Offroad. Neither gave any noticeable power gain. The best all around performance II've ever had from coils has been with the factory one. The other stuff is just snake oil. Put the money towards a mod that actually works.
>Any advice on these mods and what about actual power gained from doing these all together?
If you get a dual carb, don't waste time trying to set it up yourself or taking it to mechanics that SAY they know dual sidedraft carbs. Take it to a race shop that has computerized equipment designed specifically for dual sidedraft carbs. It'll be the best hundred bucks you ever spent on your engine!
