BillZ260 Posted May 21, 2004 Share Posted May 21, 2004 Thumbing through the latest? PHR last night and there was a Lunati new product listing for a 4/7 swap cam. Says after you install this cam you swap the 4/7 firing order. Less stresses on the crank and smoother power bands. They come in solid roller for sbc and bbc. What are you guy's thoughts on these. Just wondering... Quote Link to comment Share on other sites More sharing options...
