Old School Repair: This Dude Welds A Crankshaft Back Together Like A Boss! It Was Broken In Two!

If you watch videos from other countries, where guys are doing repairs that would seem nearly impossible without modern tools, you start to appreciate and understand what our grandparents and great grandparents were doing to make similar repairs. It’s a true testament to how good something can be even without CNC machines or what have you. In this video, the only equipment used to fix this completely snapped crankshaft is a drill press, a stick welder, and a lathe. The lathe isn’t anything new, but it does seem to work well, and the guy using it clearly knows what he’s doing. But the lathe could be 50 years old or 5, it’s all the same.

Watch as this guy cleans and machines each end of the broken pieces, which might actually be from two different crankshafts, slides them together, indexes them, and then gets his arc welding on. He then straightens the crank, machines the crank, and finally drills the oiling holes in it and then sends it on its way to be used in some truck or what have you. It’s impressive and you’ll dig it.

Dyno Proven 500 Horsepower Combos: Three Stock Bottom End 5.3 LS Combos That Will Make You 500 Horsepower Or More.

I get asked about LS engine combos all the time, and the overwhelming majority of them are from people who think that they need to build an engine with all aftermarket parts. When I ask them how much horsepower they want to make, the vast majority say something like 450 horsepower. This makes me shake my head, because making 400 to 500 horsepower is simple and doable if you have a 5.3 LS that runs. Stock they make 350 horsepower, so anything you do from there will make real power improvements. A camshaft and headers will make over 400, and when you combine an intake, heads, etc, there are real power numbers to be had. And then there’s nitrous! Okay that’s another video, these are completely naturally aspirated combos that are based on a stock bottom end 5.3L.

Check out Richard’s combos, dyno results, and more in the video below.

Video Description:

HOW DO I MAKE 500 HP WITH MY 5.3L? DO I NEED FORGED INTERNALS TO MAKE 500 HP WITH MY 5.3L? CAN MY 5.3L MAKE 500 HP WITHOUT BOOST? WHAT IS THE BEST CAM TO USE ON MY 5.3L? WHAT ARE THE BEST HEADS TO USE ON MY 5.3L? WHAT INTAKE SHOULD I USE ON MY 5.3L? CHECK OUT THIS VIDEO ON THREE (3) DIFFERENT 5.3L BUILDS THAT NOT ONLY EXCEEDED 500 FLYWHEEL HP, BUT DID SO WITH THE STOCK BOTTOM END (STOCK BLOCK, CRANK, RODS AND PISTONS). ALL YOU NEED ARE THE RIGHT HEADS, CAM AND INTAKE (WITH HEADERS) AND YOU TOO CAN REACH THE 500-HP MARK.

Ever Want To Know What Goes Into Building A 410 Sprint Car Engine? World Of Outlaws Power Starts Here!

Ever Want To Know What Goes Into Building A 410 Sprint Car Engine? World Of Outlaws Power Starts Here!

410 Sprint Car engines are pretty bad ass bullets that make more than 900 horsepower, naturally aspirated, on methanol. When you bolt one into a car that weighs just 1,400 lbs, you can imagine that the rate of acceleration is somewhere around “Oh Hell Yeah!” Or maybe it’s more like “No F’ing Way!”. I’m not sure, I haven’t driven one yet. But I can tell you that I’ve seen 410 sprint engines on several occasions and there is nothing about them that is left to chance. These engines are highly sophisticated works of art that feature mechanical fuel injection, trick aluminum heads, plenty of compression, and the ability to spin like none other so as to pull of the corner as hard as possible. They are works of art, and this is a rare glimpse into what really goes into making one tick.

Check out this great video from Speedway Motors, you’ll dig it.

Here is the info from the video description.

How do you build an engine capable of powering a Sprint Car on the Outlaw tour? Or one worthy of the National Sprint Car Hall of Fame? Running at 8000rpm night after night requires a pretty trick set up. Engines in this class get the best of the best. Zach Woods, engine builder at Speedway Motors Racing Engines, built this beauty from the block up. We could listen to Zach talk engines all day. Zach starts with a beautiful aluminum Donovan 410 block, a Callies Magnum XL crankshaft, Clevite coated bearings, Dyer’s rods and CP Pistons. A Huggins camshaft actuates the Manley titanium valves in 1 Way Technologies’ Type 60 heads. Isky EZ-Roll Red-Zone Lifters, steel T&D Rocker Arms, Trend pushrods and Manley Super Finish valve springs get installed for guaranteed endurance and stability at high rpm’s. Zach tops this work of art with a Kinsler SBC Beast injector and Speedway Motors Racing Engines valve covers. Like just about every other sprint car on the Outlaw tour, Zach runs an MSD Pro Mag.
