1972 Demon 340 engine mods
The road course is in Poland, its Tor Kielce. It's not great for big powerful cars, but still fun.
This is what new Demon owner wanted to do + sstreet driving, he did not want to build the suspension as radical as the Challenger in video, so just different sway bars and thats it. There are some cars that are less modified and handle in more "classic" way lets say.
Will check the pistons probably next week and report back. I hope ist HP as RK Motors claim, that would make things so much easier and more affordable I guess...
What kind of Mopar your son has?
