    I have a 74 with a SB 350 and i'm looking for a good set of headers and a TBI conversion. I have seen all the adds, but what is the best for the money? I want a set of headers that do not require modification to install. As far as the TBI I want a new one.

    Thanks in advance

    <font color=green> go with Flowtech Afterburner Headers. the only mod u might have to make is the bottom a/c bracket and flowtech offers a new one to run with the headers.

    I'm running an set of heddman headers. There were no mods, I got good torque, and they are not going to hit the axle when it starts flexing (expecially after a 4" lift I'm about to get).

    If you get the heddmans, make sure you get the coated ones.

    I can just here Doofy sayin that, GOOD ONE!
    The Flowtechs are probably more reliable and if I'm not mistaken has a thicker mount plate but also more expensive!

    Hmm, Flowtech ya say? I'd be interested in what others opnions are them too. I've only had word of mouth experience with the heddmans. Damn it, now you've got me second guessing myself when i want to get headers (way at the bottom because I've got to put in my 3.73 axles, new bed, tailgate, undercoating, and paint.)

    DEFINITELY Get the coating on Hedmans - I got plain painted and it looked like hell within 2 weeks. And I really don't feel like pulling them off to paint em' again (Header wrap coming soon).

    Flowtechs, the ones with the goofy tube? I'm not sold on the the out-ofsequence thing. They probably flow better than manifolds and fit O.K., but if your going to put headers on, then do itt with the normal 4-onto-1 or tri-y styles. I can tell you that dyno-max headers fit O.K. but spark plug clearance sucks, and forget about the wires. Next set I get will be the Hookers or Hedman! (i'm not ripping into anyonr w/flow-techs, just my two cents worth)

    I will have to second that opinion on Dynomax. I just bought their headers, the regular "BlackJack" style, and thought I would just paint them with some aluminum hot paint. It wasn't too fun watching those $6 cans of paint cook off of the headers after firing it up, and yes, I did follow the directions. Now my headers are somewhat the original color "black" and look like ass. I asked my buddies what they thought and they said that the regular painted ones aren't for looks, the paint just keeps 'em from rusting during shipping, and before it burns off. They told me what everyone here is saying.....spend the money to get the coated ones, so they'll look cool even after you install them. Oh yeah, and the plug access and wire routing sucks, not to mention the fact that one of the tubes is RIGHT next to my starter.....time to slap on a heat shield. Just my 2 cents.

    Stupid hurts

    yeah your buds pretty much hit the nail on the head k5_73. If you want them to look pretty then shell out the bucks for coating. Personaly I don't mind the look of plain unpainted headers... heck are you one of these guys that sits around w/ their hood open all afternoon showing off the chrome engine in a rust bucket truck? Nobody can tell when you're going through the bogs [​IMG]. Dynomax usually requires some modification (curtouscy of a 3lb. hammer). I'm interested in the Flowtech afterburners myself... sound great... but it just seems everyone get confused between them and the regular flowtechs... Hooker is can't miss. Any extra cash laid out here saves you time...BIG TIME! Every set of Hookers I've picked up (approx...8 sets of HEADERS... lol had to define that[​IMG]) pretty much jump right into the car... even the ones for my old 89 F@#d Mustang gt that I threw a 351 in for a time went in w/out too much hassle... and that gives you litterally no room.
