440ci Windsor. 600 ft-lb of torque!

Today I finished up this stout 438ci Windsor and put it through its runs on the dyno.

The aim with this package was to revise the cam profile to bring the torque in earlier and create a strong, well-rounded street engine.

Safe to say, with 600 ft-lb of torque at 4,500 RPM and 578 hp at 5,500 RPM, this Windsor will have no trouble spinning the tyres in every gear!

Something else that surprised me was how little fuel it used throughout the dyno runs compared with other engines of a similar size. Another great result from this combination.

This particular engine is available for sale now, and it’s a package I’ll continue to offer moving forward.

My engine-building books are now completely full, and at this stage I won’t be taking on any more builds until February 2027. This will also be the last engine I’ll have time to build in-house and offer for immediate sale this

440ci Windsor prepped and ready for the dyno. 🔥

I’ve really been liking this colour scheme lately. A good 50/50 split between the raw alloy/silver components and black anodised accessories. It gives the engine plenty of contrast without going too far either way.

Keen to know what everyone else prefers when it comes to an ideal engine colour scheme?

All chrome/silver?
All black?
Or a 50/50 split like this one?

The other good news is once we’ve finished this Windsor up on the dyno, it’ll be up for sale.

So if you’re looking for a strong 440 Windsor without the usual build lead time, keep an eye out. We’ll have more information coming soon along with the final dyno numbers.

WHICH ONE ARE YOU CHOOSING? 👇

Two very different ways to make serious power.

🔥 HARROP TVS TOP MOUNT
Top-mounted positive displacement blower with integrated intercooler. Instant response, clean packaging and that blown V8 feel.

⚡ PROCHARGER F-2 NEW GEN
Side-mounted centrifugal setup. Big airflow, serious top-end power and plenty of room to grow.

If you were building your engine today, which one gets your vote?

🔴 HARROP TVS
⚫ PROCHARGER F-2

And more importantly… tell us WHY in the comments.

Today’s job is setting up this set of 225cc heads.

These are a set we’ve hand ported in-house using our own high-port intake, chamber and bowl design. There’s a lot of time in a set like these, and we’re pretty happy with how this combination has evolved over the years.

We’ve got a full workshop at the moment with a number of engines in different stages of the build, so that’s where our attention is.

Because of that, we’ll only be opening up a limited number of engine build spots before closing the books for the remainder of 2026. We’d rather stay focused on the work already in the workshop than keep stretching the lead time out further.

If you’ve been thinking about an engine build, get in touch sooner rather than later.

Not all engine power comes from the intake ports. The exhaust side is just as important. Getting heat out of the engine efficiently is a huge part of making reliable horsepower.

Here’s a set of in-house Windsor cylinder heads we’re currently preparing for a 430ci Windsor stroker build. As you can see, we’re taking these exhaust ports to the absolute limit to maximise flow while maintaining reliability.

Tech tip of the day: don’t overlook the exhaust side. Sometimes that’s where the biggest gains are hiding.

How much attention do you pay to the exhaust ports when planning an engine build?

Put this 8.2 deck World Products block on the stand today and was admiring the quality of the casting and machining. They’re still one of the nicest aftermarket blocks we see come through the shop.

Then, while doing the usual inspection, we started pulling out some surprisingly large pieces of casting and machining debris.

That’s not a criticism of World Products. In fact, I’d still rate them above most alternatives in terms of overall finish and quality.

It’s simply a reminder that nothing gets a free pass. Whether it’s the best block on the market or the cheapest, every part needs to be checked thoroughly before assembly.

Trust your inspection process, not the name on the box.
