Thread: Vortech Stroker?

Tweet

Hi I am Sam From Mountain Home AFB Idaho. I have a 97 Silverado with the 5.0 Vortech V-8. I want to swap in a better Power Plant, and was thinking about the 383 Stroker Motor due to the Torque it makes at Freeway speeds (which is where I do all of my towing). Does it matter if I stay Vortech or not if I want to keep the Fuel Injection and electronics. And If I stay Vortech can I just get a Block and a set of Heads for a 350, and just swap in the rotating assembly and have it work right? I am in the middle of my first motor build right now on a 225 for my old Jeep so I do not have much experience at all. Any help is appreciated.

Yes you can build a 383 out of your stuff. But if you want to stay with same computer and fuel injection I would stay with stock camshaft and Advance the cam four degree. The computer system don't work too well with after market cams.

If you keep l your computer you will be very limited on camshaft profiles.
Also keep in mind with 70+ more cubes you will burn more fuel so make sure your fuel injection unit can handle it.

I have done one on computer and all I have to do is reprogram the computer and it will hurt the gas mileage alittle but, it will have lot of torque. I got 19 MPG on my 1994 GMC with a 383 in it on TBI setups.
