[QUOTE="NotSoPC, post: 1531376, member: 18762"] Not fair to compare the late 80's TBI to the newer LS engines as far as power and MPG. The LS was built to replace the motor and fueling that replaced the 80's TBI. I would want the 454 TBI in a crew cab 4x4 long bed. You are going to want the torque and can do mild easy mods to build a bit more power out of it. Ya its heavy but the truck alone is no light weight. I would keep the 454. If you don't plan on hard wheeling and just using it for a family play rig then the 454 will be just fine for you give you the torque you are going to need. The 350 TBI will get the same mileage or worse trying to move the weight of that truck. I had an 87 Suburban with a 350 TBI in it, and damn thing had no balls. Mileage sucked ass, and I always was put to shame by my uncles Suburban with a swapped in 454 TBI in it. Keep the 454. Edit: I missed the part where you said it was going into your Willys. If that's the case then its up in the air. The 350 TBI would be fine in that rig and the 454 would add more weight to the front then you may want. For the Willys I would trade for a TBI 350. [/QUOTE]
