This 1984 S-15 2WD pick-up has a 1989 305 Tuned Port Injected (TPI) V8 engine from a Camaro/Firebird. The transmission is a New-Venture five-speed from a 1989–1995 full-size 1/2 ton truck. This truck is smog legal in California. The interior appears stock.
With the .73:1 fifth gear and 3.08 rear axle ratio, the engine turns 1700 rpm at 60 mph. Fuel mileage approaches 24 mpg at 65 mph on level roads. Normal trip mileage is about 22 mpg. Driven conservatively, overall fuel mileage is usually 17-21 mpg. It runs the 1/4 mile in 16.0 seconds at 89 mph.
As shown, this truck weighs over 3500 lbs and gained about 270 lbs from the conversion: 155 lbs on the front axle and 115 lbs on the rear axle. The V8 added about 190 lbs, the five-speed weighs 35 lbs more than the original Borg-Warner 5-speed, and the dual exhaust weighs 35 lbs more than the original exhaust; the battery was relocated to the rear (underneath the bed, in front of the right rear tire) to improve weight distribution? this transfers about 35 lbs off the front wheels and onto the rear wheels. A gear-reduction starter and an Edelbrock long style reverse-rotation aluminum water pump reduce engine weight (and front-end weight) by about 15 lbs.
We have seen magazine articles which state the V8 conversion only adds about 100 lbs to the vehicle compared to the 2.8 V6. You should realize that these claims are not true. Most people do not realize how much weight the conversion adds because with the correct heavy duty shocks, it is barely noticeable in normal driving. We tried several brands of front shock absorbers for the V8 S-10—we now prefer the Bilstein brand shock absorbers on the 2WD models. The front shocks on the 1996–1998 2wd trucks with the sport suspension option (ZQ8) are slightly stiffer than the Bilstein, but they also work well with the V8, and some people may prefer the ZQ8 shocks. Most of the 1996–1998 2WD Blazers come with Bilstein shocks.
