Gosh, My first car was a Singer Gazelle with a Sunbeam rapier engine fitted . I rolled it onto its side after about 3 months and it didnt even dent it much, just scratched the paint a lot

I used to do burn outs on the tiny Goodyear G8's (cause every one used them). I had a Commer van diff (4.9) fitted and it would light em up, but run out of puff at about 70mph throught the twin solex carbs!

A good A12 would make it look primitive.
