Re: 99 silverado 4.3 to 5.3
i have a 2000, looking at doin a swap, and ill tell you a 5.7 swap out of an old body style will be your best bet...the 5.4/4.8 has a different bell housing and several othjer differences to make the swap harder, im hoping to do this swap myself soon, as im tires of having a beat up 4.3...
should be cheaper to find a 350 vortec anyways
