    Default header kits?

    anyone ever make their own headers (preferably through transom) with one of those kits they sell at jegs or summit? if so can you post up some pics. the fab work is easy to me, the only thing im worried about is getting the tubes all the same length, or is it even critical?

    "no budget boater" is my problem tom, you know that more than anyone. i cant justify spending half of what i bought my boat for, on some exhaust. winter rebuild list is already long, and summer isnt even over yet. need a welder up there? ill work for parts.

    i've made alot of headers for car applications before and IMHO. DON"T DO IT. In almost every single case it will end up costing more (at least more heart ache) then it's worth. YOu can buy a set in the spam section they pop up often for the cost of that kit alone. If you do decide to do it don't use the readily avaliable kits. They have thin flanges and usualy only 18ga tube. find a tube supplier or a header manufacture and buy a bunch of bends in at least 16 gauge and heavy flanges..

    not what you want to hear im sure but thats my advice search the spam section.

    tahiti, appreciate the words, but i have a sbc and have never seen a set of thru transom headers for sale used. tons of logs, but im looking for headers. ive seen a few kits that were pretty cheap with 3/8" and 1/2" flanges and they come with way more tube then i will need. im looking at doing a similar style to the lightning 90 degree ones

    Deggo-

    I've built a lot of headers in my day, I say ****it! What's it going to cost other than the material? If you take your time, measure, measure, measure, then make your cuts, you should be fine. BTW I have a good source for nice thick flanges, and very very tight radius bends (Donuts)


    Available in mild steel or stainless steel, the only difference is the price. I've also thought about using some of Sanderson's headers and modifying to fit the boat, hit Long Beach swap meet, there's usually a few pair of headers laying around, or wait for the Big 3 @ Qualcomm.

    Good luck

    sorry didn't catch the sbc part. Building a good solid working set of headers is a task.. I think the drawing luckiestiff put up is the easiest approach. No need to reinvent the wheel, buy an existing set (cheap car headers) and chop them up. and to answer your question about equal length, it's not reeally that easy but there is alot to tunning a header for max performance. If all you want is the look of a header with better performance then just build what fits. If you want an all out header well then we could write a book.


    *edit* I just went and look at what the header is your talking about, looks fairly simple. all you need is a couple 180 bends for each tube. id weigh the cost by the time you buy flanges and tube you migth be able to buy a car header really close to the initial shape, cut off the collector and add the tube you need.

    at any rate good luck, and if you need any help let me know.

    I would leave that thing with logs IMO, leave it a cooler small block cruiser as it is.

    heres "one" of a set Josh started for his Windsor , a few years back during the last big CA noise scare the "loop" was neccesary because of the extreme set back on his jet but I think they would have worked well Tom
