How are your plug wires routed? It's common for consecutive firing cylinders to stumble/misfire if the wires are run parallel/close to each other,...
I agree it looks like a custom shop made setup. Seen pictures of similar before. The issue with these is the 2-1 cylinder firing sequence, so...
Have a 220lb Trenton dated 1927. Also a couple chunks of rail. [ATTACH]
Not to speak for him, but I think the point is that not all factory 9" are equal. There are small and big bearing varieties (both wheel and...
The GM 14 bolt also uses a 3rd pinion bearing.
Ford went to the tapered rollers with the transition from F-100 to F-150 (and E-150). Gross weight was increased to avoid the EPA requirement for...

It should also be noted that the SET20 tapered bearing requires a specific axle shaft to work properly. The external seal area needs to be...
The tapered bearings handle side loads better. They came about with the transition from F-100 to F-150. Ford pushed the GVWR over 6000 lbs so they...
EGT gauges were not unusual to install on 2-stroke motorcycles. The piston is fuel cooled, so modified engines are often run excessively rich to...
It's still radius rods, just square tube instead of hairpins or split wishbone. Looks like a parallel leaf axle, so tube was the easiest thing to...
An analog volt meter will show the pulsing, cheap digital meters will read all over the place. Not sure how a top shelf digital will react as I...
I have a pair of 15x6 as a set with the 8-1/2". They have the stem between the spokes as there isn't room on the narrower, lower offset wheel to...
For reference, here are my American Torq Thrust with a logo. Shallow lug recess, no ribs. American Racing Equipment ALUMINUM TORQ-THRUST WHEEL 8...
On a Model A, the VIN is the engine serial number. Nothing on the frame. So title goes with engine.
Reverse is typically non-synchronized, so it is engaged by sliding an idler gear between the main shaft and counter shaft. Straight cut teeth are...
My Dad used Kodachrome. [ATTACH] [ATTACH] [ATTACH] [ATTACH]
Also depends on suspension locator type. Parallel 4-bar could benefit, but with split bones, hairpins or ladder bars, the axles are the anti-roll...
A stock 302 has non-adjustable valvetrain. If the lifter is ticking, something is out of spec. The rocker studs are just pressed in and have been...
The power loss is from friction and rotational inertia. Thrust washers/bearings and unengaged clutch packs rotating with fluid film between them....
For a temporary outdoor booth, positive pressure doesn't need an explosion proof blower. If the booth is inside another structure, then negative...
2-3 flair is most commonly caused by one or more; loose intermediate band, excessive direct clutch clearance, low line pressure, sticky valve...
The M112 has a displacement of 112 ci, max rpm of 12,000. You didn't state engine displacement or max rpm, so I'll make generic assumptions. If...
Standard speedometers are designed to display 60 mph at 1000 rpm. Calculate driveshaft rpm from gear ratio and tire circumference, then you'll...
Measure across TDC, not BDC (110° + 114°). Convert crankshaft rotation to camshaft rotation (divide by 2). If you're wondering why use the wider...
Ford was still staking wheel studs to drums through the mid 70's until front drums ceased on light duty vehicles. '74 drum [ATTACH] [ATTACH]
WCZ-V1 is 8" open 2.79 28 spline '67-'70 Mustang/Cougar 8J- is the date code, year -68, month-Sept. day- 2.79 ratio 8 inch ring gear 930 factory code
Before I retired, calibrating the torque wrenches was part of my job. Assembly, Engineering and Test Lab had them. Assembly was mostly air tools,...
Each auto manufacturer had a trade name for their clutch disk limited slip differentials. GM Positraction (Positive-Traction on early versions)...
Vintage carbs may be a zinc alloy, typically Zamac (zinc, aluminum, magnesium, copper). Less porous than aluminum, but more expensive. Zinc...
Separate names with a comma.
