The heat riser clang...

My gosh, been half a century since I've heard one of those rattle. I put headers on my 69 383RR (about fall of 1970), my 70 440-6, about 71-72, came with cyclone headers the 1st owner had installed, and the 340 I swapped in later I pulled the thing out and stuck a bolt in there. Soon after, put headers on THAT. Only thing I can remember with one since was the original 273 in my 67, which got yanked quickly, and this 74 Scamp with a slant, and IT does not make enough POWER to clang!!! LOL
