    Hey there..I've been wanting to ask..did you have any water/seapeage.leak problems when you had your log manifold water heated? I've been thinking of using that setup on a spare engine for my 85/camper,

    Good evening, I was looking at your pictures of your 4bbl conversion. What manifold gasket did you use?
    I have a Mr. Gasket 260, but in your pictures I see a multi gasket being used.

    hey ive tried to look around on the forum and havent been able to find an answer to this question so i thought I'd go straight to the top. I have the EFI exhaust manifolds on my 1984 4.9 and had a plumbing cap over the port that comes out of the rear manifold. Im not sure when, but it fell off. It wasnt threaded on very well, as it wasnt the exact thread pattern. I didnt force it when i put it on there, and it doesnt look like the threads are ruined. What is the best way to block off that port? I dont want to pull my manifold to go hunting around for the right threading, i suppose i could just get a thread pitch gauge. I probably should just have one of those anyways.

    I am just now getting around to putting on my Summit carb to see if I can pass the emissions tests. That being said I noticed the conversation between you and F250 concerning the jet size that should be used. The stock jets are 67 on the Summit carb which I think are to big. Would I be better off rolling with the setup that we discussed previously, or should I look at going with the size 49-52 jets that F250 is looking at?

    I haven't gotten the throttle shafts repaired because I am moving into a city that is going to require an emissions test and I think that the Summit Carb will give me a better chance to do that. I am not going to get rid of the carter, I have my eye on another 300 project that whenever I have the time and funds to build it will go on it when it is repaired. I still have not put in a 3.25 rear yet, because I have not had the time to do so yet, so I still have the stock 2.75 unit with the SROD. Would it help to go to a 27 squirter because of this? Thanks for the help.

    Hey AB,

    I have a question about carb tuning. I have a 1980 F100 that I have converted over to a four barrel setup that is similar to yours, except that I am running a 485 cfm carter wcfb carb and Clifford manifold with headers that I picked up in a barn and rebuilt. It worked fine for the first year and even returned good mileage, 20 mpg, but now it has developed a massive vacuum leak around the throttle shaft and the mileage has dropped off to 16. I have just purchased a summit racing carb, the mv8600 which runs about 600 cfm. It is based off of the old autolite 4100 series so it has annular discharge which I think will work well on my 300 six. That being said the summit carb uses holley parts and I am looking for some advice on which jets, cams, and squirters to use so I can get close to the right tune on my vehicle and work from there. If you need more information let me know.
