does neone know the stock horsepower and torque for the 90 chevy halfton with a 5.7 350? is it the same for a 91? i have a 91 engine in my 90 chevy, i was jsut wondering about how much horsepower and torque it came with from the factory, its a silverado model ext cab half ton 2wd short bed if that helps with nething? thanks guys

p.s. neone know of some really good websites that i can find aftermarket parts for my truck? besides like jegs and summit, like some performance sites and some suspension and interior sites, that dont have outrageous prices, ne of the sites would be very appreciated!!

go to www.autotrader.com for power and torque ratings. my favorite performance site is www.truckperformance.com

ok i went to autotrader.com and i have no clue on how u found the horsepower and torque specs, maybe u can send me the exact site or tell me how to get there??

Can you specify different engines? The only options that I saw were year/make/model/trim level. The 4.8L was the only engine I could see.

200 hp
300 ft lbs

ya J-Ri i understand what u mean i go to msn autos and try to look and it gives the 6 cylinder and the diesel engine rating but it has nothing about a 305 and 350 engine? but thanks abaird for the ratings
