i just got my tired 305 out about 15 mins ago.. it was a pain in the @$$ it took almost 5 hours to get out. im excited tomorrow my 357 is going in it is a +.040 350 with 10.3:1 compression with an LT1 cam and erson 1.5 roller rockers. The motor is going in with a set of Dynomax shorty headers and a tru dual exhaust setup with flowmaster 40 series mufflers.
