Grafting an LS Head Onto This Turbo Ford 300 I6 Engine Took Years

Standard Motors’ LS V8s are outside of commonplace in the car or truck nut universe. People swap them into everything—Porsches included—and even though they’re the fastest way to impress on a dyno, they are not specifically groundbreaking. That is part of why Jaron Nelson decided to turbocharge a Ford 300 inline-6 and make it his possess by modifying a set of LS heads to suit.

Now, Nelson is just not the 1st to do this, but I would wager that his engine establish is the most sophisticated of the class. It can be taken between two and 3 a long time of his absolutely free time to create, but unless of course you know what you happen to be performing, this sort of swap is all but not possible. Improve will make it even trickier, but last but not least, Nelson’s engine is running with a laundry checklist of modern mods to make it all occur.

“The motor by itself is far more generic than a human being thinks,” Nelson says, underselling it by a good deal. “It is stock bore. It has inventory pistons, crank, and rods. It has two #241 Camaro [LS1] cylinder heads welded jointly.”

Whilst you can find some aftermarket help for the Ford 300, there are key aspects that limit the engine’s general performance figures. Nelson identifies the cylinder head as difficulty numero uno. The stock unit doesn’t stream nearly plenty of to guidance his electric power ambitions, and neither do the handful of completely ready-made alternatives.

Nelson is employing his LS knowledge to address this equation which features an motor he bought off his father-in-law, a GT45 turbo that value him $163, and a ton of spare GM parts he experienced lying all around his store. He tells me he’s about $1,500 into the project, but you are unable to undervalue the amount of time it really is taken to get anything operating proper. He’s also uploaded in-depth explainers to his YouTube channel, Piston Ranch.

Nelson experienced read through about previous-time drag racers fitting V8 heads to inline engines in the past, but their strategy was really archaic in comparison. They epoxied the cylinder heads alongside one another and ran a trio of Weber carburetors, which resulted in solid energy, all points thought of. Continue to, they ran into cooling challenges that would kneecap any undertaking that’s intended for the street.

“I determined that I desired to do it otherwise than that. It is really a great deal of welding and likely in between the bores and welding, there is a whole lot extra to it, in particular if you happen to be trying to seal up the coolant passages. Alternatively of undertaking that, I reduce the stop cap off a cylinder head, centered the center two cylinders on the cylinder head, opened the hole dimensions up, and basically I cut an additional two cylinders.

“There are a lot of coolant ports on the LS head that actually have to be welded shut. It takes advantage of a Ford 300 [head] gasket,” Nelson proceeds. “The 1 issue folks don’t think about is pushrods and pushrod angle. So the pushrods, if you have been to not have a side include on the motor, the pushrods would go midway outdoors the block. You have to basically reduce your pushrod holes out of the block and make the pushrod tubes line up so they’re a little bit canted out. You have to make a custom made side cover to hold your force tubes enclosed and retain oil within of the motor.”

It has a set of inventory Chevy truck injectors that are decapped, a mod that allows them to operate approximately 80 kilos per hour according to Nelson. He designed the total harness himself by having from a bunch of 2000s Chevy Suburbans, and it has a GM P01 engine command module. That offers its very own difficulties mainly because Nelson is managing coil over plug ignition, and GM never engineered it with the expected logic to operate a 6-cylinder on unique coils.

“Brandon with Turbo_V6 reached out and wrote the code that I could flash on the ECM that would travel it. It is really tuned by means of HP Tuners—the first tune that I place in, I experienced to use PCM Hammer for the reason that HP Tuner will not assist what it was carrying out. It’s flashed and it can be a 3 BAR map program so it really is set up for improve.”

As soon as Nelson had accomplished all that and bought the ingestion figured out, which he suggests was specifically tricky, he was ultimately capable to get it running in October.

Eventually, it’ll go in his rat rod which is titled as a 1935 Chevy. It has a “hodgepodge” of other areas, including a top-loader four-pace transmission and a Ford 8.8-inch rear-finish.

“I know you can find some stuff out there that has made 500 hp at the flywheel, and that is cool, but that’s not really what my goal is. I am gonna hang the rods out of it. I’m just curious what the stock bottom conclude can take care of. To make 500 hp flywheel would be fairly amazing, but I would rather it make about 500 hp to the tires.”

You can see this Ford 300 just isn’t the only big undertaking Nelson has taken on. But in the close, it’s going to energy another just one of his homebrewed creations which is respectable on its possess. This Frankenstein engine just seals the offer.
