Would love to do this, not under the title, mentioned. Wonder what set up was on that Chally.

If the same as original then the engine (if that is what you are asking about) was a Keith Black built de-stroked 340 (to bring it down to a race legal 305 max inches) making 450hp. It was clocked at 160mph in testing. It ran a single 4bbl carb. But it was not that trick really.

I don't know what suspension and brake upgrades were made. But there was a lot of work done on the car to make it lighter.

Suspension set up Dave, as he was talking about the handling and the way it was leaving the corners.

Not easy to find information on that. I would love to know myself.

But it does sound as it it was pretty solid.

They had to use stock heads and block in that racing series so I suspect they couldn't do a lot with the suspension except uprate the stock type system?

A typical full competition set up with stock type suspension would have front spring rates over 300lbs/in and massive 450lbs/in sway bar. The rear would not have to be so highly rated. 130lbs springs with adjustable sway bar.

But what was actually done to these Trams Am cars i don't know.
