I have a 1990 formula , 305 tpi with dual cats , 5 speed , and t-tops. It has alot of options also. Question is should i restore it or can i put a 350 tpi in ? If this car is somewhat common , I will do the 350 , but if it has a low production , I might keep it stock. Any suggestions ????

 

My opinion: keep it stock.

 

I have the same car(minus t-tops and accent stripe). I think the 305 TPI 5spd G92 Formulas are pretty rare. 1990 was a short model year as it is, and most of the Formulas I see are 305 TBI or 350 TPI. Keep the stock motor and mod it. These models are particularly desirable right now and they will be more desirable as time goes on. It was the fastest F-body(regular production) that you could get with a stick.

 

i am keeping my formula stock for the most part

need to get another thirdgen for my weekend racer.
