Depending on your cam shaft you may want your advance to start early or a bit later so find out your cam profile and where the lowest point of torque is made. |

Re: Restoring Rusty
Advance can be adversely affected by one more setting that's usually ignored...
What's the end play on the distributor gear. http://www.chevytalk.org/fusionbb/showpost.php?post/1257140/Measuring HEI gear end play. It should be 0.010" +0.004" - 0.000" but most are set up way too loose. Every 0.0128" is 1° of advance as the gear lifts so the closer you can get to 0.010" the better. It's cheap and easy to fix...

Re: Restoring Rusty
To answer some earlier questions. I am running 16-17 base timing. That is, timing without the vacuum advance hooked up and with the idle slowed to about 600 rpm.
The GM HEI adds 20* mechanical advance, so I am running 36-37 degrees total timing. The AR23 vacuum advance adds another 15* (spec is 7.5*, which is camshaft degrees), to make 51* all in. 51* is what the advance is at cruise, 2500+ rpm, with the throttle plate mostly closed (not accelerating), so the mechanical and vacuum advance are both in. I have seen 52* given as an absolute maximum for cruise "all in" timing. Check this: http://67-72chevytrucks.com/vboard/s...d.php?t=689321

There's no gasket there just shims and an odd spacer. At .062 you'll need three of the five shims in the Moroso kit... 2x .020 & 1x .010 should get you .012 clearance or even .011... 1° timing float isn't bad at all. http://www.summitracing.com/parts/mo...FYomhgodmgEDkQ The gasket or spacers between the intake manifold and the distributor housing will fix the distributor bottoming on the oil pump drive or block if that's an issue.

Re: Restoring Rusty
Not sure. I know it was messed with a bit before I got it. I know it is 20* all in, and I also know it doesn't come in below 800 and is all in by about 2500. They had the correct (AR23) vacuum advance can on it, which is not stock, so I assumed they played with the mechanical as well and I just left it alone.

Re: Restoring Rusty
picked up some MasterPro RAMCOA rubber bushings for my anti sway bar from O'Reillys. They were only $8.00 bucks a pair, and I must say I am rather impressed and excited to give them a go, they are made in the USA and seem pretty nice
not sure why one pair came in a bigger box (dated 2012) than the other pair (dated 2016), they are identical I have not favored the eurothane bushings everyone seems to talk about in the past, in my opinion rubber bushings are designed to cushion the situation and those polyeurothane things are essentially spacers and just make things rigid, sorta defeats the purpose in my mind I looked at the MOOG ones but for some odd reason their 1-1/16 ones only came in BLUE green truck and blue bushings, come on man! that would totally cramp my style, how was we going to go fishin' lookin' like that |

Re: Restoring Rusty
a little stare and compare of the old ones and the new
I can't wait to try these, I don't think I ever had an anti sway bar before, it must be good for at least 20 horse power, ha ha |

Re: Restoring Rusty
i gotta tell ya, I paid less ($3.61) for all the 3/8ths Grade 8 nuts and bolts on the left at Blue Collar Supply than I did for the twelve locking washers on the right at ACE Hardware
this is for the anti sway bar, I usually don't like using the gold stuff on my vehicles but since this aint going to live in the engine bay I think it beats cleaning those old bolts by the way do any of youz know if the cad plated "gold" bolts are better than stainless in terms of rust resistance? |

Re: Restoring Rusty
and some close ups for those in the cheap seats
I gotta ask: Do it matter which way the open ends of the rubber bushings go/face ie towards the front? or the back of the vehicle? |

Re: Restoring Rusty
On a 2wd truck that is lowered the stiffer you can be the better the road handling is. Rubber is fine but requires replacement more often than poly.
One thing your new bushings do not have is grease nipples to keep them working and being supple. Regarding the slit no it does not matter and just becomes preference. |

Grade 8 hardware has 50% more tensile strength than stainless steel hardware. Grade 5 hardware has 20% more tensile strength than stainless steel hardware. No comparison. Stainless steel hardware sounds good at first blush, but you probably don't want to go there.

Re: Restoring Rusty
Slippery Grip Garage was closed yesterday on the account of it being 104° F
so we opened early today at 0600 and installed the new purple(ish) 43 tooth driven speedo gear and that little baby seal we put some white lightning grease on the shaft of that gear and around the big rubber O-ring we also topped off the transmission with some Red Wine (ha ha) Good News: now our odometer is only .1 off for every 6 miles we drive, good enuff fer now, IT'S A TRUCK! |

Re: Restoring Rusty
time for Doo Dadz, I don't know about you, but I like doing finishing touches like this, makes things look complete, makes it look like it was meant to be
we ended up using one 3/8" and one 1/2" |

Re: Restoring Rusty

Passivated 304 & 316 stainless, either by oxidizing in an air furnace or treating the surface with an acid to cause an oxide to form, is much better at resisting galling but is also more expensive.

Re: Restoring Rusty
Monday, drove the truck in to work today! Great feeling guys I'm sure you all can relate after pulling off a big project. Truck runs strong, windows down, wind in my face, its going to be hot driving back home this afternoon, but the morning drive was glorious.
Speedo is spot on up to 50 MPH than deviates slightly and is about 5 MPH off by the time I'm doing 75 MPH on the highway, maybe tire pressure and a different tire size can dial it in further, but for now it will do, most of my driving aint on the freeway anyways Ordered a new rear window seal from Classic Parts (love their printed catalog, yes I'm old school and it makes for a great toilet read, ha ha, also it aint got no salt & pepper shakers nor bunch of "universal" parts, nothing but essentials, plus its all in COLOR cause it's 2016. - I'm looking at you LMC Truck) hope to install that tinted slider window next.

Re: Restoring Rusty
went out and bought a Mr. Gasket inline fuel pressure guage at AutoZone, wanted to see what my current fuel pump is delivering before I replace it (on the suspision that that's where the ticking noise is coming from)

since they didn't have a single piece T with two 5/16 hose ends, I had to get these fittings

Re: Restoring Rusty
got it all installed and learned that an inline fuel pressure gauge with a mechanical fuel pump jumps around constantly as the car is runnin' so it aint much use, I did turn the car off and ran and took a pic before the gauge fully dropped, here it is a few PSI lower than when its running
Pic 1 - truck off, just showing you the gauge installed Pic 2 - right after I shut it off and captured some pressure |
