This is setup on a modified engine for performance in a Discovery.   Bill Malloy (Wam) New Member Username: Wam Post Number: 13 Registered: 11-2002 Posted on Monday, February 17, 2003 - 11:42 am:    Check these sites for info: http://www.ajmac.co.uk for general info http://www.v8buick.com small block tech -search for threads with posts by Ignitionman. He's running a 4.6 block, p76 crank (longer stroke), and modified Buick 300 heads. Sounds like fun.
