Re: Vintage race motor

Like many, I really like the ST style cars, and I'm thinking about building one to vintage race.

I would like to build it as correct as possible, and I'm thinking about an engine based on the one of the earlier original recipes/variations of 66x85mm, twin plug, 46mm carbs etc.

Number one question is concerning the engine case. It would be nice to keep it somewhat period correct. Any problems using a circa 1970 case? I would anticipate somewhere around 230-240 hp.

The original STs were 85, 86.7 and 87.5 mm bores. If authenticity is your goal perhaps we should talk. I might be able to get you a set of authentic ST pistons and cylinders.
As for the case, you can use almost any case with the correct prep work. Early aluminum case are the easiest, mag cases are the lightest and the 7R cases are the strongest. The key is knowing what your case needs in the way of prep work in order to get the best use of it.
If you really want authenticity look for a 72, 2.4 7R case.
