Hi, Im sorta new to VAdriven
i got this from a website......is this the same truck you have?
This 1984 S-15 2WD pick-up has a 1989 305 Tuned Port Injected (TPI) V-8 engine from a Camaro/Firebird. The transmission is a New-Venture five-speed from a 1988–1995 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 18-21 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: 160 lbs on the front axle and 110 lbs on the rear axle. The V-8 added about 190 lbs, the five-speed weighs about 35 lbs more than the original 5-speed, and the dual exhaust weighs 35 lbs more than the original exhaust; the battery was relocated to the rear to improve weight distribution. This transfers about 35 lbs off the front wheels and onto the rear wheels. A gear-reduction starter and an aluminum water pump reduce engine weight (and front-end weight) by about 15 lbs.
We have seen magazine articles which state the V-8 conversion only adds about 100 lbs to the vehicle. 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.

Kinda. Mine has a 355. 355 because it has been bored .30ths over. Mine is an automatic. Also i wish mine would get 22 mpg, i get like 8 on a good day. Damn pop top pistons. I also have to run atleast 93 octace.
I have taken my S10 down there a couple of times i ran a 7.52 which isnt bad considering i cant seem to get traction. I plan to move the motor back about 4-6 inches, so i can get better center of gravity. Which means more traction.
i dunno man, i think it would still have to weigh over 3000 pounds, even gutted, according to that article. i wasnt calling bs on you, i just think you may be mistaken.
