The engine in this vehicle is positioned 1" farther back than a "stock" position. This allows more room for the engine-driven cooling fan that is required for towing.

The vehicle now weighs about 3560 lbs. It gained 170 lbs from the conversion—190 lbs on the front wheels, and 20 lbs off the rear wheels. A gear reduction starter, and the lack of the AIR pump reduced the weight of the V8 conversion by 20 lbs, when compared to the 4X4 S-10 Blazer shown previously.

With the original fuel-injected 2.8 V6, 700-R4 transmission, and 3.73 gears, the truck averaged about 23 mpg on freeway trips, With the V8 and the 3.73 gears, the truck only averaged about 18 mpg on trips. Changing to 3.08 gears brought the freeway fuel mileage up to 22 mpg.

The stock 2.8 V6 would pull a 3,500 lb trailer up a nearby mountain pass at a leisurely 40 mph. With the 305 TBI V8, the truck pulls the same trailer up the same hill at 70 mph. With three people in the truck, 0-60 takes 9.6 seconds and it does the 1/4 mile in 17.4 seconds at about 79 mph (using a Vericom 2000 Performance Computer for measurements).

The engine swap was done when the truck had 152,000 miles. Herbie's truck has over 320,000 miles. It's had three breakdowns‹The first time, the ignition coil died. Later, it was determined that the coil was damaged by a bad spark plug wire arcing into the coil (Coils rarely fail without a reason). The second time, the original in-tank fuel pump failed at 280,000 miles (but it gave a warning by making excessive noise for about a week before it quit). The third time it broke down (at about 281,000 miles), was when the ring and pinion in the rear end broke. It now has a 7-5/8" rear end from a 4.3 S-Truck.

While not considered breakdowns, the alternator was replaced at 250,000 miles and the water pump began leaking at 295,000.
