In my days of dirt track speedway, I drove a ford Anglia with a chev straight 8 in it. Didn't fit but it didn't matter, safety was just another word. As long as there was a chain slung under the motor, and the roll cage was sound you could run anything you liked. Rear wheels were two 6 inch rims welded together, tyres fitted and then a liquid rubber worked between the tyres until it set, hey presto 14" fats on the back.
Radiator sat behind the driver near the rear window. No glass anywhere in the car.
