you'll get bored with a stock 305 before you're done with your first day. They're also not very consistent. Depending on how the next few months go for me financial-wise, I MIGHT look at unloading my zz4 and TH400 combination. They're built to be a mostly strip sometimes streetable combo. Not terribly fast, low-mid 13s consistently, and if someone could dedicate some more tuning time to it than I can right now, it will easily be in the 12s. the TH400 is already race built with a reverse manual valve body and B&M shifter, zz4 is bored .030 with JE pistons, a .509 lift cam from GM performance and MSD 6AL. If it's something you'd be interested in, but not for a little while, I'll keep you in mind, as im not sure about selling because it would probably destroy me
