Probably kinda hard to find Holman & Moody side oiler 427 Ford engines these days . Dusty
Any FE series engine, which are all based upon the same basic architecture and challenging for most people to identify from the outside, would still be a far more equitable substitute. Except for the heads of factory-installed main bearing cap cross bolts (3 per side) visible along the skirt just above oil pan rail, there's virtually no consistent way to externally identify a 427 short block from any other FE. Many smaller displacement 66-67 blocks had side oiler passages that weren't drilled and even had 66 427 cast on the rear of the block, even though they were only a 352 or 390.Even a plain 390 in a replica GT40 would be fast enough for anything needed in the movie. All the dress up goodies that fit a 427 will fit a 390. They're still plenty of them around and lots of us serious FE fans, including this one who keeps his two Guzzis parked next to his original 428 red-on-red 1967 Galaxie 500...
It may be a feel-good movie as long as you don't look too close. the repro GT40s in the movie are reportedly running small block Chevrolet engines instead of real Ford engines. This has been under discussion for a while on a Ford forum that I've been on for years. Not a good pr move imho or that of other serious Ford fans. The Ferraris probably aren't running original Ferrari engines either, but the movie isn't celebrating their results.Kinda like doing a movie about Dr John starring a CX500-engined versions of his bikes...
Then what you need is a documentary , not a Hollywood movie . The documentary would also need to point out that Shelby spent more time in court suing someone or getting sued than doing anything else beginning not long after the success at Lemans . Tricky thing this accuracy thing . Dusty
The GT40 Mk II big block 427 was a detuned NASCAR engine with dry sump and aluminum heads. The idea was to run at lower RPMs to run 24hrs. The Mk II couldn't handle more power due to limitations on brakes and it was already faster than the competition.
Na$car heads aren't well suited for the street as they are made to flow best at high rpm and a narrow rpm range. And the cams are the same. I fact, last I was told you can't get your hands on a na$car cam. That tech is kept close to the vest.I saw an article on the making of the movie. It showed the cars going round the track with all the camera equipment attached. They might have been going 30 mph.

Most FE heads are configured to Low Riser, Medium Riser and High Riser intake port architecture. The taller the port, the higher the flow & typical performance as rpm increases. Drag racing and NASCAR engines were most often dedicate high rpm engines, which is High Riser territory. Road course engines needed more mid range, so are more typically Medium Riser heads. medium riser heads were used on the factory-built 427 Ford street cars from 65-67. 63 1/2 & 64 427 street car engines were Low Risers. this same architecture was employed for the 428CJ (with similar large valves) as well as plain jane street FEs in other displacements (used smaller valves) because they provide lower rpm benefit. High Risers were available in the early years for racing use but were unsuitable for the street, hence the development and release of the Medium Riser heads for the 1965 model year. They are a performance improvement over the Low Riser heads without the extremes of High Risers. Tunnel Port and SOHC top ends are different than LR, MR and HR for dedicated high performance use comparable to the HR heads. 30-40 yrs ago, there weren't many options for aluminum heads for an FE. Used Factory parts were the most affordable and Medium Riser heads with an appropriate factory intake are fine for street use. Many things may be kept under wraps about NASCAR secrets in the larger population, but it's different if you are in the right area and know the right people. 50 yrs on, many of the "secrets" aren't very secret anymore. Right now, NASCAR corporate is moving to standardize the engines used by everyone. Pay for & use their engines or don't race. Sorta like what's under the hood isn't the point, no matter the badge on the hood. It's just entertainment.
Going to see it as I've been Ford from birth. Hope Eric Broadley is mentioned.
Ford was involved in all motorsports at that time, trying to dominate some classes of drag racing and Nascar and then to road racing...Ferrari was a very small company with a racing budget at that time of less than $350,000..Ford was the second largest vehicle manufacturer in the US and probably the world...A story of how massive money can bring success...
Yup, these early SK alloy Medium Riser heads were known for porosity issues with the castings. There were some around here via local NASCAR channels. I always wanted a set for my old 428 Galaxie when I was a kid, but was advised against using a set on my car. Now there's a variety of modern aluminum heads for the engines, including some contemporary Dove reissue castings of the old SK with better metallurgy.Lots of racing stuff here in Spartanburg but the parts that used to be common (and cheap) aren't anymore. So I've built a repro Holman Moody-style cowl plenum air cleaner for my Galaxie. That whole project was on the front burner until this V700 came home..
Not to get too far into it. The GT40 Mk II aluminum heads were done solely to keep the weight down. Weight and brakes were the achilles heel for the car. Those heads had smaller valves than the NASCAR engine and lower compression. It was meant to run at 6k rpms but could go to 7k. Most of this was also mentioned in the movie.
