my firebird has t-tops. i put the sfc'* on mine but people also tell me if i dont do a 6pt cage too im going to start getting cracks. i dont have a cage at all i really need to do that.
i had a 86' 305 for my third engine, had it tuned up pretty good, a couple mod'*, 3.23'* posi, 700r4. best i could get was 10.4 1/8th. at the time i bought a new 5spd neon for my DD and dead stock it would run 10.0. so that inspired me to get the 355 crate engine, theres something wrong when your dd is faster than your hobby car.
