All Aluminium 1957 250 Testarossa

I think you made a good decision also ...is a 7 chassis the way forward may be easiest but I take it you'll be modifying it somewhat reather than just throwing the body on it

Are there other chassis that may fit like a tr chassis????

The 7 style chassis are a good starting point. If you look at the shape of a typical 7 with swept back front wings you will see that the Testarossa has some similarities. The seating position relative to the rear wheels is also similar as is the long nose forward of the cockpit. When the outer panels of a 7 are removed you are left with a neat, light weight space frame. Even down to the suspension, the Testarossa was a live axle at the rear with double wishbones at the front, same as the Westfields etc. Wheel base and track are also very similar and as I said before, I wouldn't want to modify the bodywork to suit a chassis. If a 7 chassis is that close I shouldn't have to modify that either apart from adding mounting points for the body.

My comment was based on my driving experiences of a 7 ok for short blasts but quite focused and tail happy

I've owned 2 Westfields and several of the early monocoque Robin Hood 7's all with various engines from a 1600 Ford crossflow to a tuned 3.9 Rover V8. I also had a Ginetta 27 with a Rover V8, with an Escort live axle.
You are right about the characteristics of the 7 but the bigger engines with matched diff ratio make them far more drivable.
Remember the 250 TR was a small car designed for the track first and foremost all be it with a big engine. The original TR must have been a handful with the V12 engine and skinny tyres.
