    Marvel mystery oil used as a lead substitute?

    4 oz to 10 gallons for fuel. MM was developed for radial aircraft engines in WW2 era. Google it and you can find an article of the development, it's a good read. I would run what you have and not worry about it. You may have induction hardened and not even know it. The auto industry knew...

    Rear end advice for racing with a 4 speed

    By the time I narrowed a dana, bought gun drilled axles from Moser and installed rear disc brake setup I was within 10 lbs of the 8.75. I got tired of fixing the 8.75 and decided to go dana.

    Sure grip housing... send it?

    In post one the ring gear is off. Install the carrier without the ring gear installed and set the carrier bearing preload. Mount up a dial indicator and check the runout. I believe max is .004 but refer to the FSM. If it's out of spec it screws up the Backlash when you check that. You tube has...

    Mancini/HS 1.6 rocker not giving me the lift expected

    I ran into this recently with Hughes 1.6 aluminum rockers. I was missing out on over .045 lift with the correct length pushrod and finally saw the difference of the adjuster location to the centerline off the rocker shaft on half of the rockers I received. Look over your rockers and use a...

    Lean idle. Rich cruise.

    You can solder some of those .028 shut. A tiny bit of flux cleaner and you will have no problem soldering shut from the bottom.

    Base Timing Questions

    Since you have an MSD adjustable timing box set the timing to 25* initial timing with VA disconnected. +-7* adjustment will allow you to figure out the best idle timing.

    O2 Sensor on a Carb Engine Question

    I've had mine read pig rich when the engine was starving for fuel. Heat soaked motor and fuel boiling off in the fuel pump. Car would barely run at idle with fuel bowls empty. Acted like the motor was drowning in fuel until I saw the fuel level.

    Intake distribution issues

    I run a carb so this may not apply. I briefly ran that intake on my 360 with a square flange plate, 1" 4 hole HVH Super sucker and a 750dp carb. 3, 6, 7 cylinders were rich. I swapped to a Victor 340 square flange intake and 3 & 7 are rich. Car runs great with either manifold but I'd like to...
