Innards are different. One side gear is thin with a clutch hub next to it. Center block has pre-load springs. Traction-Lok only has a clutch on...
Mid-late '70s F-150 calipers have 2-7/8" pistons. '72-'79 Thunderbird/Lincoln Mark calipers have 3-1/16" pistons and bolt in place, so they are a...
Ford also dropped compression for '72. Mostly with dished pistons, but a couple blocks gained compression height as well. 351W went from 9.480" to...
Most single seat race cars use some form of cowl steering. This one has an interesting take. Appears to be a conventional steering box under the...
There are 2 flavors of C4. The small bell for 157 tooth flywheel. The bell bolts to front pump and the dipstick tube is in the case. Used on...
The readily sourced pickup truck engines are a bit odd for deck clearance/quench height. The 360 is a 390 block, 352 crank and rods with 390...
I have a "Model Craft" book from the '50's that has several model engines in it. You would buy raw castings, then machine and assemble the pieces....
Miller was using quarter-elliptic springs as a 4 bar for the front drive car in 1923. This stuff wasn't common for the average hot rod, but the...
Hairpins and split wishbones single pivot point work with the pre-'35 side steering box and drag link location having coincident pivot points....
Early hairpins were made by pinching wishbones, like on this T from the 1932 movie "Hot Saturday". [ATTACH]
Buy square tube and cut it.
Can you swing both? Keep the good parts, repair and resell what you don't use.
250 is the same length as a 170/200 just taller. I've read that Maverick engine mounts will mount it lower. The 240/300 is the longer one. 250...
A worn timing chain jumping a tooth. Ignition and cam timing will be retarded. Cranking the starter with ignition disconnected, fuel-air vapor may...
A 390 truck/410 piston has a 1.66" compression height, correct diameter, for 10.09", .080" below deck.
I had the same thought. I have an air powered nibbler. It's fast but makes a mess. Keep the shop vac running when using it. I do always take my...
Brake cleaner leaves no residue. Carb cleaner leaves a light oil film, so not ideal for brake parts.
A 406 has the same bore as the 428, but the piston is still .136" below deck with the longer 352 rods. The 360 pickup engine was a 352 crank and...
I measured a big block toploader ('70 429) and a NP435 from an 80's pickup with a 300. I get the same as Marty on both. Maybe 3-25/32". [ATTACH]...
Hobby-horsing is another term I've heard to describe it. Common on short vehicles like old Jeeps. Freeway expansion joints will get it rocking on...
The flaw is that they are aluminum. Aluminum has no fatigue limit. Steel, as long as the load stays under the yield strength, will last forever....
FYI, the 250 was also used in Maverick and Fairmont, and is a tall deck version of the 144/170/200 block but uses the small V8 bellhousing pattern...
It is an exact equation. Design of the torque converter determines the K factor. RPM= K*sqrt[torque] This is late model stuff, but shows some...
At the top of the page, below the red bar are some grey icons. Hold the mouse pointer over the person icon on the right. Your user info will pop...
Steel is real.o_O Not much lower back support though. [ATTACH]
The small input is 1-1/16" splines, the big input is 1-3/8". Both are 10 spline count. The 6.5" is the small block length, with 1-1/4" long pilot....
This is smaller cars with behemoth engines, but similar theme. [MEDIA]
This video shows the original machining process at 6:20. Castings can also "settle" over time. Heat cycles will relieve stress and allow things to...
When looking at the gears, it's the small engagement teeth on the side that are the concern. The main reduction teeth rarely have issues, it's the...
I have a '74 Bronco rear apart in the garage. The big bearing, small brake, "Torino" pattern. It has the 1-5/16 cylinder mount. Early Bronco rear...
