well, I reckon that engine would be just wonderful sitting on a display stand as a piece of automobile art - it is totally schmick ! well done guys - I now wish I han't sold my Mini Moke - then I could embark on recreating something as nice as you have done. I would have to worry about the driveshafts though !

120hp to the wheels for a 1275 is pretty stout.

Why is torque crossing HP at 6,700 RPM? Should be at 5,252 - that's a lot of artistic license on the dyno sheet.

In reply to Frank Wissman :look at both sides of the graph. Torque and HP are displayed different scales.

This makes Huffaker's engines look like toys and costs more than his original cars! --so much for an inexpensive racing class as intended.

Thank you for the great article! Approximately what was the total cost to build  and how many hours? Also what were/are the specs of the gasoline you utilized for the dyno run and your team's track time? Have you built any 1500 motors? Our team uses them for rally, trialling, and some limited track time, no redlining of course! Sorry, it's a lot of questions, but we are always interested in folks buiding these engines. Thanks again for the great article.   --Dr. Paul Lynn. Hochkraeusen Racing Team, Ohio

Good article.

I dod a similar thing when I grafted an MGA Twin Cam head onto a 5 main MGB Block - it stayed together and put out 160 bhp at up to 7900 rpm!  Lots of details to modify and upgrade to keep everything together.
