    290hp 350 Cam Replacement

    Ok, the gutless wonder has finally pushed me too far. All my research shows basically the engine is a problem from day one due to GM grabbing mismatched parts etc etc...so my first step is a new cam. Comp Cam XE256H is apparently the way to go...I know jack about this stuff but that seems to...

    700R4 issue

    First major 500 mile road trip. Here's what I found. In overdrive it lacks power simply traveling down anything more than a flat road with no wind. Had to shift it out of overdrive to get anywhere above 65mph and stay there. In overdrive, it down shifted constantly at 2000 rpms which brought...

    Even better...bought and installed the bowtieoverdrive geometry correction kit and had the tranny shop install. Called bow tie and told me what was happening and they told me that it was acting as it should and I need to shift it in such circumstances...

    Edelbrock Carb #1406 Calibration & Reference Chart

    I set my 1406 to: Secondary jets are .101 71/47 rods with #5 orange spring Primary jets are .098 Fuel plunger rod set to top position which eliminated a slight hesitation off the line. Floats are properly set and new fuel plunger installed. More power than I've ever had get up and go...

    700R4 issue

    Truck is done. Bore brush cleaned out the three valves. Wouldn't lockup and checked, previous owner disregarded wiring harness for older tranny so had to cut in new pigtail for electronic lockup? No clue about that whole deal. He says it goes down the road at about 1500rpm, but it's still...

    700R4 issue

    Update: tranny finally installed! My installer tells me bow tie overdrive used all new parts and made sure they were premium grade products (governor, shift kit, servo, etc). However, on test drive it wouldn't shift from 2-3. Bowtie authorized opening and investigation per warranty. 3...

    700R4 issue

    On the highest, at 60-70 mph cruising, when I come to a point that I have to slow down,,,a machine gun vibration starts...can feel it in the whole truck and it's not a slight vibration either. So then if I shift it out of overdrive it runs fine, no slow down vibration. Stopped at a red light...

    Powertrax Lock Rite locker?

    Yes or no? Seems ok to install and good pricing. All online research shows positive feedback...any good reasons not to? Anyone using one?

    Bad Bad Bad...Bad Vibrations

    At 65mph a vibration starts from underneath. At 70mph is quite loud (loud enough to hear) and the rear view mirror is shuddering. It is constant and increases in volume gradually and then decreases gradually and then increases gradually and then...you get the idea. This started after I...

    Edelbrock carb add-ons

    Ok fellas, I have a 350 engine and 700R4 tranny. The carb was never setup correctly by PO. That being said I am wondering about the two brackets below. Which do I need or do you use both or do they both do the same thing? I know my throttle return spring connects to the wrong place. My...

    Gutless Wonder

    I think I've made some headway. 1. Timing set at 10 degrees. 2. Vacuum advance set to 10-12 degrees...it was turned all the way in. 3. Silver and blue springs put in distributor to replace stock springs. 4. Pass side vacuum port was being used on carb, but I should have been using drivers...

    Gutless Wonder

    Here's what I've done/noticed. On the vacuum advance canister I took an Allen wrench and backed the adjustment screw all the way out. Then I screwed it back in 4 turns which gives me about 12 degrees. I do now notice a more effective quicker advance under load. Should I add in a vacuum...

    Gutless Wonder

    The truck's acting up. Acting like a 180hp truck. Pulled a pontoon and couldn't go over 55mph with any wind...then it'd have to shift to 4th gear to make any moderate incline causing it to almost over heat. Not much for power, if I floor it from zero it tries to get up and go but not as...
