engine and driveline setup on type 105
I am new the site and excited about all the information I've found so far!!
I'm starting a build of a '50s style racing sports car with Alfa and Ferrari influences. I had a Duetto many years ago and decided to use an Alfa 105 inline 4 DOHC engine and drive train. This is not my first car project but certainly the first "from scratch" build.
I've start making drawings of the body, chassis and placement of components. But I need some info that I haven't found with simple searches. I want to follow Alfa specs on these items to avoid complicating things.
1. At ride height, is there an specific angle the engine expects to be mounted (from front to back)? I know some American cars require a few degrees to angle so the nose of the engine is up slightly.
2. What pinion angle should I use on the rear axle when installed at ride height? Again, some US-made cars can range from 1-2 degrees or more depending on the suspension type.
3. And related to #2, what do the specs call for on a 105 driveshaft angle?
Any insights would be greatly appreciated as I start this journey.
