My 94 Suburban 383 is kind of screwed up even tho only has 24,000 on it. Bent a pushrod, beat up the valve but having trouble finding an intake valve to replace it. So we're looking for another vehicle. A lot of the Burbs or Tahoes have the 5.3. Is that any good for trailer towing?? I think our TT weighs about 5000 lb loaded.
