Maximize Camber or Caster

I am trying to do an at home allignment while the world is on fire and I can’t go to a shop to get it done professionally. Ride height is set how I want it. I have the UCA adjuster all the way in on the rear and in the middle on the front yielding
Driver side
-1.2 camber, 1.2 caster (calculate using 20°turn in/out camber measurements)
Passenger side
-1.3 camber, 2.1 caster

Turning the driver front side adjuster all the way out I get
Driver side
-0.2 camber, 2.4 caster

My target is -0.75…

Metal Body PC Seals On Stock Guides

Has anyone run a modern metal body positive seals on a stock guide? I was looking at these from Comp to try to control oil better on my dad’s 360. The heads are not machined for smaller pc seals and he is currently using stock umbrella seals. I think 3/8 × 0.500 would be the right diameters for stock valves and guides.

Delayed Starting

I am having a problem with my roadrunner not starting correctly. I turn the key to start and hold it there for a few seconds before it starts cranking. How well it cranks is intermittent between ‘dead battery click’ to a belabored few normal cranks, but some times I get nothing at all. Luckily my 318 starts really easily so I have been able to start the car and move it around home. Anyone have an idea what is wrong?
Here is what I have diagnosed so far:
1. It’s not the starter. If I jump the…

Large Port Commando on a 340

Is anyone running large port commando (P5153850) or w2/w5 head on a 340 on the street? I am interested in hearing how they perform with a smaller engine and how drivability is (any loss of torque from port air speed at lower rpm?).
LP Comandos are available for about the same price as RPMs and considering them if they don’t detract from street manners. (I know of good priced set of w2 rockers so that cost would be a wash between the two)

Fast Idle Solonoid

Is anyone running a fast idle solonoid when their A/C compressor engages? My engine is bogging down from 600-650 rpm to 490rpm at idle, in gear, with the A/C on. I would like to keep idle around 600-650 in all conditions and was looking at adding a fas…

Magnum Engine Oiling Mods for LA Heads

I am considering a 360 magnum block as the base for my next engine build simply for the availability in junk yards and roller lifter provisions. I dislike the valve train Chrysler switched to for the magnums and am not interested in running inferior st…

Datalogging RPM Signal

I have an LM-2 data-logger that I am trying to use to tune my car. I have one wideband O2, TPS, MAP, and a Narrow Band O2, but it is all kind of meaningless because my RPM is not working. I have talked to Innovate about it and they have not suggested much beyond adding the potentiometer (which I did from day one). I have even sent the logger back to Innovate and gotten a replacement, but that didn’t change anything. Has anyone else had this problem?
