Tools made by Danaher/Apex are sold as:

Here for easy reference.

Tools made by Danaher/Apex are sold as Armstrong, Craftsman, Masterforce, USA Crescent, USA Kd Tools, Kobalt, and a few others.

Snap On also makes tools for Williams or CAT... maybe a few others. williams makes tools for others.

J.H. Williams and Lowes originally partnered to manufacture Kobalt tools, but since 2003, Kobalt tools have been made by Danaher. Chervon makes Kobalt’s cordless power tools
Here's a good look at who owns who which leads to who makes what.

This site uses the tools barcode to identify the manufacturer.

A good thread that identifies "tool truck" equivalents.

Improved SBC Timing Chain Oiling

In the plug in the passenger side passage, drill out the plug 0.030" (1/32") to spray on the chain. You can also drill the other two plugs to release trapped air, but it's not necessary.

You can tap the plug holes with  a 1/4' pipe tap and use pipe plug, but use a shallow plug for the center hole so as to not to block the oil galley behind it.

Oil pump pickup should be held 3/8' to /1/2" off the bottom of the pan. When located correctly, weld the pickup in place.


Block Plug Basics, Super Chevy

"Most small-blocks feature four 3/8-inch threaded holes (two per side) at the front of the block. The upper hole adjacent to the fuel pump passes into the crankcase area and if left open will allow oil to leak out from the block. Be certain to plug this hole only with a short 3/8-inch bolt (1/2-inch long). Because this hole aligns perfectly with the fuel pump’s pushrod, a longer bolt will contact and seize the pushrod during engine operation."

Handy MIG welding reference.

Typically , the best cruising range for an engine is from 2,000 to 2,400 RPM. Here are some formulas to help you calculate the best gearing for your car.

mph = (rpm x tire diameter) ÷ (gear ratio x 336)

rpm = (mph x gear ratio) x 336 ÷ tire diameter

Gear ratio = (rpm x tire diameter) ÷ (mph x 336)

Tire diameter = (mph x gear ratio x 336 ÷ rpm)

Gotchas for SBC Timing

There is a gotcha for timing for small block Chevys that can cause problems if overlooked .

User "oldboogie" at the forum at said,

Unless you appreciate that the crankshaft and damper pass the timing tab twice in a revolution which puts different events happening at each place because the cycles (of the cam) are happening at half the rate of the crank. So for argument starting at a point where both the number 1 and number 6 pistons are at TDC lets say this in cam (thus distributor position) is ready to fire number 1. At this same time the cam has number 6 also at TDC of crankshaft but it is finishing the exhaust stroke and will commence the intake at the same time number 1 is on a power stroke. At this point if the timing cover was to be removed the timing mark of the crank gear and the mark of the cam gear would both be in the 12 o'clock position.

Now rotate the crank one full turn, both number 1 and 6 are back at TDC but number 1 is finishing exhaust and about to start the intake cycle, while number 6 has finished compression and is about to fire and start its power cycle. The timing mark on the damper is at TDC as the example above, however, with the timing cover removed the crank gear mark is again at 12 o'clock but the cam gear mark is facing it in the 6 o'clock position.

This quirk of the SBC catches a lot of engine builders including experienced ones. the reward is an engine that seems to want to run but doesn't quite get there.

The other is the distributor being off a tooth, this is forced by alignment of the oil pump drive which rotates with the distributor any time it is removed. This drops what seems to be the TDC point by 27 and some fraction degrees. The engine will start and run but has no power and backfires a lot yet appears to be timed correctly. This also bites a lot of people.
