My car is 305 tbi car. Ihave a 98 350 vortec with a carb setup.how good wood the vortec run on tbi?

 

I ould guess it would run OK, and the power should be about the same, but you will need a TBI manifold to bolt to the Vortec heads. Personally, I would avoid going to TBI as I see no advantage to it, a TPI or a Holley injection would give better results.

 

pete If I went tpi , hows the best way to do it?

 

Not worth the time, money and effort. Too much to change from the TBI to TPI setup and nothing on your car is compatible for that TPI swap..

 

The Vortec heads do not mate up to the TPI manifold. You may try a MPI injection from Holley or Edelbrock, but I am not sure they will fit either. Scoggin & ****ey advertises a TPI lower intake baseplate to fit Vortec heads, which will mate up to TPI runners, this is probably the best bet. You could also check out the FI system used by GM on Vortec V8s. In all cases you would need the appropriate computer and wiring harness.

 

thanks guys. as usual can't make up my mind let you know when I do.
