I just want to make sure and I really don't have time now to do my homework but is there any difference in the T-5's from a TBI or TPI car?

Thanks

 

Gear ratios, that's all.

TBI cars have the "gas mileage" .63 5th; TPI has the more usable .76 5th. All others are the same.

 

That doesn't really sound like a bad thing at all.

Thanks.

 

1st gear is different too. TBI has 2.95 ratio, while the TPIs had 2.75.

The .63 vs .76 5th gear is a big difference when the 4-5 shift comes at WOT. The TPI car just feels like shifting another gear, while the TBI car falls on it's face.
