    Default Rock n Roll and some carb questions

    Alright guys, I've got a few questions for you.
    For starters, I'm upgrading from points in my distributor to a GM style HEI
    I'm currently using about .035" Plug gap, how much further can I open this up with the HEI?
    Also at this time I will be upgrading from the Holley 1 bbl to a 2 bble.
    Now what would you guys suggest? A Weber 32/36 or a Holley 300-350 cfm.

    Also, I have a unique rattle that I've tried tracking down but I'm unable to find where its coming from,
    Whenever I take off from a dead stop the whole tranny/transfer case shake and rattle side to side pretty damn hard.
    I've looked at all the mounting bolts and everthing is there and tight. I'm at a loss for this.
    It's a '71 Scout II with the 258 I6, T-18 Tranny, D-20 Transfer case.
    '71 Basterd Scout 2
    with a 258 from a '73 CJ5
    Intake manifold with NHRA markings....go figure

    could it be a busted tranny mount ? it will flop around a bit. crawl under with a pry bar and see if anything moves.

    IH Only and IH Only north make them. Pretty good folks to deal with.

    Yeah I agree, Ive had nothing but outstanding service from them (and parts always come quick) Only negative i have is that i have to pay sales tax on IH ONLY NORTH, but they can hardly be blamed for being in California as well ha ha

    There have also been several threads on the different forums as to making your own tranny / t-case mounts with hockey pucks, thick rubber, old dead blow hammer handles / heads, etc...

    Personally, I went to the local IH truck dealership / service center and ordered the stock mount over the counter. They had it in the shop 3 days later; your local shop may have two in stock. Part number Dyco 311 aka 879627R93

    I have dealt with Jeff at IHonly North, You're all right...they're great peoples to deal with.
    I'll check to see how it looks tomorrow with the prybar.
    Now about that damn carb, should I go with the Weber 32/36 or a Holley 300-350?
    And how far do you think I can open up the gap on my plugs with the new HEI dizzy?

    I have the 258 in my '74 and went with the weber 32/26. I kept the ol' carter around as a backup, but it's been working well. I've got to reset the idle / choke twice a year to get it running well for the different temperatures that we see up hither (-60*F to +70*F).

    I still have the stock dizzy, so I haven't modified the plug gap, can't help you there.
