    Changing gear ratios: opinions/suggestions wanted!!

    Twenty-five years ago if you would have told me anyone was buying a 3/4 ton truck just to commute with I would have laughed in your face. Nowadays its commonplace. Hell I wonder why Denali/Platinum/Laramie trucks even come with hitches..

    No driver's side rear turn signal or brake light, because no power at bulkhead

    If you have a tilt column the wire might be broken at the swivel point. Usually there isn't enough space to repair it though. A new switch comes with that harness.

    No driver's side rear turn signal or brake light, because no power at bulkhead

    You probably need a turn signal switch. There are two dogs in the switch that move (literally) between the brake and turn signal input and complete the circuit when the lever is moved. The right side dog is probably burned out, i would say this with near certainty if the front blinker works...

    Big block running hot. Can’t figure out the issue

    I gotcha. They would have to put the ribbed side to a smooth pulley or vice versa, and that would be hard not to notice. Its a convoluted routing, but either the pulleys are on the inside of the belt or outside

    Big block running hot. Can’t figure out the issue

    In a serp setup any pulley that is turned by the smooth side of the belt is spinning opposite of the crank, any pulley that is spun by the ribbed side turns with the crank. Nearly all serp setups spin the water pump reverse beacuse the belt goes between the crank and water pump in an "S" route...

    Changing gear ratios: opinions/suggestions wanted!!

    I wouldn't put a 700 in a 3/4 ton truck, that's a step backwards.

    Big block running hot. Can’t figure out the issue

    It's probably not the cause of your ovwrheat issue based on your symptoms, but you should check your total timing and power time it. If you are running stock advance weights and springs you are leaving a lot on the table. There is no reason to throw head gaskets at it at this point. It passed...

    Anyone running Wilwood clutch master

    I have a wilwood 5/8 master in the hotrod. Works great, probably 15k miles and over 300 passes at the track.

    What are your cruise AFR and total timing specs?

    Olds 350 diesel to sbc swap

    An olds 455 would have been a bolt in swap! Cap the lines until you're ready to drain and hook them up..

    Heavy vibration at highway speed under load

    Bad motor mounts will create an odd driveline angle that can cause a vibration. I would start there. The rotational slop in the driveshaft is probably worn spider gears and cross shaft, especially if you have been doing burnouts all over town.

    Engine stumbling/stalling in drive

    Pull the vacuum and check it again. The vac adance skewed your numbers. It'll probably smooth out after you readjust.

    Engine stumbling/stalling in drive

    Did you unplug the vacuum advance when you set the initial timing?

    Please help me solve this riddle

    The residue you are feeling is normal condensation under the valve cover. You're not losing coolant and you have decent compression and it runs fine 90% of the time. You don't have a head gasket issue. I would clean the egr valve and check the fuel psi..

    Changing gear ratios: opinions/suggestions wanted!!

    The OD ratios in the newer 6, 8 and 10 speeds are not much higher than what was offered in the 80s. I'm not here to argue but turning 3k at 70 is far from useless and is acceptable.

    Changing gear ratios: opinions/suggestions wanted!!

    Despite popular belief turning 3k on the highway is not a problem. Hell I've turned 3800-4000 for hours on end...

    Changing gear ratios: opinions/suggestions wanted!!

    A 4l80e with a standalone computer would be pretty slick here, otherwise I would go 4.10s.

    There definitely needs to be quantifiable data before you start throwing parts at it.

    never jerk a stuck truck with a chain

    I must be the only one here with farm experience. Chains are the only thing that will move a 30k tractor

    Gas hog

    Does it stink like fuel? Is it running ok besides the idle issue?
