How far are you racing? Man thats a tough call for me to get that thing even close on gas. Start with a big ass main just to be safe (though you'll probably end up with smaller mains that a 4 mil Cub, etc because of the 10 mil Stroke.) Maybe 175 mains to start?? Should be plenty fat. I ran 170s (I think) on my 421 with 39 pwks and it was fat. I forget what needle. DEL maybe?? 55 - 60 pilots will get ya going, maybe not perfect, though. Quote
lt1bird Posted January 21, 2009 Author Report Posted January 21, 2009 I plan on using it for street riding only, not drag racing..... I plan on using my wideband a/f gauge and will weld a bung in the pipes for tuning... Just figured I could save some time. Thanks for the info Quote
