    Well everyone I wrote Edelbrock about AL cross flow heads for a 300 ci ford. There reply was 'IT WOULLD COST $50,000 for tooling to even start.' Maby if everyone interested in the heads would write them a e-mail they might be inclined to make some. :)

    Gear suppliers

    Has anyone thought of using quick change gears from rear ends? I found that Richmond has a 3.5 center to center operating distance. They seem to be able to take some serious power for extended periods of time. Mel
