    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. Run the engine up to full operating temp with the hood closed and turn the engine off. Wait 5 minutes and allow the engine to...

    (2)450 DP's vs (2)750 DP's

    One flat may do the trick. Middle of the sight glass has always been best for me. It looks like the PJ comes in at 3400 by your readings.

    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.

    How And Why Move Emulsion Jets?

    1) the middle gave me the most stable and flat fuel curve at cruise and WOT 2) see 1 Think of the emulsion as a means to tame the fuel flow to behave in a stable, predictable manner. Now add or decrease jetting to run the afr the combo likes the best.

    How And Why Move Emulsion Jets?

    I run a 360 [email protected] cam, sealed hood scoop, return fuel system and 750DP Demon. I drive this car on 93 octane pump gas 50 miles to run at the track.

    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...

    I would also make sure the valve guides aren't to tight on that cylinder since you had another failure.

    My 340

    I always go by effective length but some manufactures use overall length. The EDM SFT lifters I use are basically hollow hyd lifters with the EDM hole. Very light and hold up well on my street/strip setup.

    Is that pushrod 8" long? I've always ended up using a pushrod in the 7.2 - 7.3 range. I having never run the heads you have but I would definitely be looking into pushrod length and valve train geometry.

    My 340

    What's the ICL at now? You should be in at 106. What 750 do you have? Are you capable of tuning it? I run 28*initial 34*total timing. Air gap works very well with your rear gear /converter.

    Vibration (worse) after 904 rebuild

    The small outer circumference weights are normally there to neutral balance the converter. External balance are then added for particular engine balance.

    Drag Times Density Altitude Calculator close to correct?

    My car runs very close to correction. You can keep some data notes and try to run your car this fall when the air is better. Closer you are to 0 feet the smaller correction if your tune and chassis setup is right.
