    Hi all!
    I have a'48 chevy coupe with a 305/350 combo. Recently replaced a homemade tranny crossmember and raised the tranny 2-3". Now, the idle is smooth as usual but when put into gear the motor bogs and stalls if allowed.... The only thing that I think was effected was the shifter linkage.
    Any thoughts??

  2. Is the vacuum modulator hooked up?

    Make sure the distributor cap isn't making contact since you raised the trans.

    Do a stall test, should be able to go over 1500 against the brake. if not the converter overrunning clutch is bad.

    Maybe got the TV cable out of adjustment?

    I installed the carb a month or so ago, ran super from 1st start. would that angle change cause a float problem? possibly an air/fuel mixture change would help?
    Thanks,
    Mack

    Vac line from tranny is connected. was runnin great.... I'm stumped as to why the angle change has made a diff. I could understand if it was grinding/screeching as if something was bound or rubbing against something else but....
     
  10. There is no TV cable on a T350. Just a kickdown cable.

    Compression check. Make sure all cylinders are makin power.

    Either a plugged idle circuit, or the engine is tired...

    A hell of a carb angle if the engine is tilted to far forward, you might need jet extensions in the front???? Is it a Holley? try raising the float level in the front bowl.... That would be a hell of a lift...

    What is the Carb pad angle? Your phone probably has an inclonometer app available

    Could the distributor have contacted the firewall and changed timing a bit when the cross member swap took place?
     
  14. What's the outcome here ?

    Hey guys,
    Sorry, I got a bit sidetracked.... I pulled the plugs and found one was fouled very bad with an oil leak from the rear corner of the valve cover. changed the plugs and the cover gasket & she's back in business. The carb I think still needs to be tuned a bit due to the new angle but, NOT bogging when in gear now.
    THANK YOU GUYS!!
