I have a '65 1200 40hp. Just gave it a tune-up and wanted to get anew carb. I am in the process or sourcing parts to make it a 1385. What carb upgrade would help wake it up until that time. Would a 30 PICT do or something larger. Would prefer to have something that is usable now and after I rebuild to a 1385.

Are there decent dual carb options still available with little to no fabrication for SP heads?

Any particular reason?

It works with the factory 1200 distributor, and it is easy to work with. you could use a newer 31 PICT3 too. but then you would have to swop distributor too, and the difference in performance will be minor if any, because the restriction will be in the 1200 intake manifold.

if you want to go dual carbs, there are several vintage suppliers over here that make and sell manifolds for 1200 heads and varius carb solutions. I do not know about the US though. On the other hand, they are not that difficult to fabricate for a skilled steel guy.

Can I throw in my 2 cents? I did the 1385 upgrade in my 65 1200 a couple years ago. Was hoping to keep the stock 28 PICT1 carb if possible, but it was no problem if I needed to step up. I have various 30 and 34 series carbs. Put the car on a chassis dyno and found the stock jetting to be real lean. Kept increasing the main jet size until I had a nice A/F ratio. Amazingly I ended up with a really big main. I dont have my log here, but I am pretty sure I ended up with a 130 main, which I think was about the same as the air jet.

The car runs VERY well. Feels about the same as a stock 1600. BUT I do still have the stock transaxle, so it is geared a little shorter than a later car would be.

And the exhaust not is kind of cool when I get on it...Much throatier. When I started tuning, the exhaust had a much thinner sound to it.

If I am at the shop tomorrow, I will find my log and check the main size.
Oh - and I am running one of Glenn's 019 distributors. I do have one or two stock ones that I may try at some point. Was running a Brazilian 009 and it just wasnt as smooth.

30Pict2 or 30pict3 would be my choices, or an H30/31 in good shape would work. Grab a vacuum-only dizzy (I like the 205k or 205m personally) if you don't already have one.

Do you have 40 horse heads or regular later style (1300/1500) single port heads? 1300 heads will work with a pair of ICT Weber carbs if jetted properly.

I had a 1385 with 1300 heads and ICT's in a 66 beetle a while back. Tractor torque in a light early car. it was a placeholder engine until I finished up a 1600, but sold the car and engine before building and swapping.

Put some oil bath air cleaners on it, rock the vintage speed look. Surprised

I should have mentioned that I have an 009 mechanical dizzy and not the original. I purchased this 1200 last year and the PO said it was "stock" wont really know until I split the case and go through everything. Where is "over here" and does "over here" ship to US?

Would love to see the logs..I am running a stock jet (122.5 I think). What heads and cam did you use for your build? So many options and variations out there would appreciate seeing what you did since you have the dyno numbers to back it up.

I haven't taken a really close look but I believe they are later style 40hm heads. Didn't know the 1300 heads would fit w/o machining. If that is the case - didn't they make 1300/1500 DP heads? Would those also bolt on?? That would open up a whole new catalog of dual carbs.

good luck finding 1300 dual port heads that are in affordable decent shape here in the US, they weren't put in US spec cars.

I have the "65" square boss heads. Other than a standard valve job, nothing special. Running stock exhaust and that may be hurting me a little, but wanted to keep the car as stock as possible. Will try to remember the log book tomorrow, but the jetting was a huge difference. I found and older post I did about it and 130 main was what I used. I saw a comment that when I went bigger than that, it really hurt and kind of remembered that happening. And yeah, these things are jetted pretty small. Yours sounds about what I started with.

Some folks don't really realize how much of a difference a couple steps in size can make.

I think I mentioned that I have a stock geared transaxle, so even though the car is still pulling strong at 65, I don't like taking it above that very much. Just as a butt dyno observation - when it was stock, I would be grabbing 3rd about 3/4 up this long hill and just making the top at 40-45. Now I pull the whole way up at 60 in 4th with the big bore and the jetting. A late car with a 1600 DP will almost do the same.
