ok so i have looked all over the forum and i cannot find what i am looking for. i just bought a 1990 Chevy silverado stepside with a fresh rebuilt 350 with new tranny and new full stainless exhaust. i cannot find the hp and torque spec for an engine like that. does anyone of you know a ballpark estimate on something like that all i need is a ballpark estimate. it dont need to be exact.


also. if i start a build thread, does it have to be for a blazer or can i start one on my silverado? just wondering.

 

Should be somewhere around or just above 300rhp for that setup. I'd get it dyno'd just to be sure.

 

Stock HP for a 1990 350 TBI is 210 HP at the flywheel and torque should be around 250ish.

 

The build thread is open to all projects.

 

The old Throttle body 350's made 210 hp and around 250 ft lbs of torque.

<edit> ok AJbert... I just saw that you beat me to it!... lol

 

hey thanks guys. that helps me out alot. i do have a friend with a dyno so i might go talk to him.


as to the build thread...... i will probably post some pics of it first, then tell everyone my plans. thanks alot guys.

 

one more question. Does anyone know the bolt pattern on the 2wd. Chevy trucks. I know it is a 5 bolt but is it 5x5, 5x4.5, 5x4.75, extra. I don't know. So if you could help me one last time. Thanks y'all!

 

It's a 5x5

 

Hey thanks man. If I have anymore questions I will just post them on this thread instead of starting a new one.

 

No problem, good luck with the build.
