GT40 Engine Article

Pretty good article on the GT40 FE engines and some great pics. Just thought I would pass it all along...

How Hot Rodders Built a World-Championship-Winning Engine in 1966

Uh...."Peak torque was 4,000 lb-ft at 475 rpm."
Basically they said Ford kicked their asses and didn't even try.

Sounds like something you'd find powering a tugboat.

That's a good article with great pictures too.

It's funny...years ago I would have thought that there's nothing better than a high revving, peaky Italian thoroughbred engine, but as I grow older, I see the appeal of a simple, big 'lazy' lump that will do the same job and have superb reliability as well.
I still have an Italian thoroughbred in the garage, but it isn't a really high revver, it's not (very) temperamental, and it's best attributes (apart from the number of cams and the type of carbs) is that it is tremendously torquey from idle, yet revs freely to its redline....just like a well developed 427 as in those great Mk IIs that won at LM in 1966 or that equally well developed 302 (ref. GT40/P1075) that won in 1968 AND 1969. Oh, and the 289s in 1965 that whipped Enzo's butt.
It is good to be able to see both sides clearly. Got to say, it is also good if that big lazy lump has a quartet of twin throat Webers feeding it too. Best of both, maybe?

Cheers, buddies!

I was hoping it was a large error in the typing.

Since 4000 lb-ft at 475 rpm is an easy error to spot, but it does read 400 lb-ft at 475 rpm.

So now we need to do the maths.

Being a race engine of the time, I'd say the torque peak was 4750, not 4000 rpm?

So there you go, the error should read 475 lb-ft at 4000 rpm.
