Hello All. My 90 4x4 suburban is on its way out. It has the 350TBI original engine with close to 300K on it. Rebuilt transmission about 10k on it. It’s pushing 33” tires which aren’t that big but I can tell shes getting tired. I’m researching engine options to get more power. Would like to have power when I need it on and off the road as well as a good Daily driver. Fuel economy is not a factor and I rarely tow. I was thinking LS swap or 454. I’m open to suggestions. Or if anyone has done this and recommends against it I’d like to hear that as well. Thanks in advance
