I was thinking of dropping a 350 from a 90 GTA 5.7 v8. I was thinkin of keeping the car TBI and not changing over to TPI, how much more power will the TPI get to me if i go with that. If I was keeping TBI i would get a Holley TBI and open it up a bit. Well any input would be great. Thanks Alot. Murph

 

You would gain alot of torque by using TPI. If you used a holley TBI unit then you could probably get almost the same horsepower as a TPI.
