[QUOTE=KEN BUGAJ;556369]Stock was diluted in the late 70's when they changed the can & valve spring rules. There's no more stock,. It's modified stock.[/QUOTE
Ken......Stock as we knew it died in 1985. That was when NHRA allowed any valve spring pressures and any duration and overlap specs. Last edited by X-TECH MAN; 02-16-2018 at 08:25 PM. |
