Guest Posted December 3, 2001 Share Posted December 3, 2001 I'd like to get some more performance out of my 425 without drastic mods. My '65 Gran Sport is running a '66 425 with '66 heads and a stock intake with an Edelbrock 625cfm w'electric choke. I intend to swap the stock intake for a '66 Spread Bore and a 750cfm carb. I've heard recurving the distributor can give me some more performance, but where do I find the parts? Are there any other cheap and easy mods? The Lark is currently running with a ST300, which I plan to swap for a ST400. The rear-end is stock and not posi. I think the ratio might be 3.08:1<P>Thanks for all input, Link to comment Share on other sites More sharing options...
