What is the standard on the most compression

first i ever herd of it was late 80s hotrod artical trying to build power on 87 octaine and pass smog test in komie-fornia... attention to detail can make power with anything!

Yup. Just like this thread around here where everybody is talkin about the 340 Duster whoopin up on a big block early Vette. In their dreams. ONE car pulls off the seemingly impossible for probably some tunung or technical issue on the other and suddenly Mopar is king. I got news. Mopar lost their fat share of races, too. I don't think a lot of these guys have ever stood next to or ridden in a 396/425 Vette. I have. NO stock 340 Duster would make it around one in good tune. Ain't happenin. Dream on. lol
