I just saw a couple posts on the bird about this car; have not been active over there but was still subscribed to a thread re. Otto.

What was the original engine...anyone know?,not a lot of money for a car with that sort of history.

I was part of his pit crew when he raced at PIR. He raced in the under 3.0 liter class. So it was a 2.9 something motor with webers. Don’t know if it was an SC block or earlier mag case. I have pictures of it somewhere.

Here is a link to Checkbook Chucks car built by
OTTO,

Is this car the infamous Rudy that JW raced? They had a memorial for JW/Otto and did some laps in the car.
Also a shot of Rudy on his memorial page. https://yovenice.com/2013/02/10/rip-john-otto-williamson/

Here is a shot of Rudy at PIR many years ago.

Engine looks like it is long gone from this car.

I think part of the discounted price has gotta be that the car has not actively competed/driven in years now so would need extensive refreshing and tech approval. The ginther windscreen and lack of front rollcage hoop limits where it can be raced.

The engine was a 2.8/2.9 high-compression build as I recall but I don't know specifics. In later years it did have Motec management but not sure about the induction setup. Short gears, strong torque and large slicks made the car a monster at tight tracks like Streets of Willow. I got a brief trackside ridealong once -- it had no passenger seat so this prob was sitting on a beer cooler -- very quick and loud, obviously...

I am not sure how many cars that Otto built. The current car being sold by Don Ahearn is an early 1970 original six; serial appears to be 9140430157, but last digits are not distinct and could be 69.
Otto's Rudy was supposed to be a 1971 914/6.
Chuck McKinney had Otto build a conversion from 4742906456 about 1989. This was owned by Steve Lannoch until sold in 2015.
Anyone who has VIN information on any of Otto's cars should contact me.

pretty beaten, but is a real six chassis. I would think more like 15 because someone would have to totally reconstruct it

There was also a yellow GT-flared car built at Ottos in the mid 2000's as I recall from a tub that had burned to the ground out by WSIR. JW called it the "burn victim" and it was campaigned a bit with POC as a 3.0 with carbs.

It had a full roll cage..
