The trans ratios are so low in the available Fiero trans that you don't need bottom end torque..... you just need to learn to shift fast enough . I'm using a HE cam in my 377 Fiero with, as I recall, around 490 and 510 lift and 230 duration. sounds like a lot for 9.7:1 but it works well given the total package. I also use an Edelbrock performer RPM cam in mine at one point. it was rather peeky, but worked pretty well also.
