Okay soo i know this is a noob question. I am debating on rebuilding my top end, but dont really want to. I am pretty wrapped up in bulding my race car, and am a full time college student right now so its not like a have a whole lot of time, or funds. I was told it was rebuilt in 2011, and has probaly 12 weekends of HARD rides on it. i always ran 93 octane with ocatane +7 booster with amsoil dominator 42 to 1. I am not very family with banshee engines, but have done my far share working on big block and small block chevy engins so i think i could handle it. i guess i just dont want to wast a weekend of riding if it siezes. Should i do it now or wait till after summer? i was told the engine is all stock? if i wated till after summer i think i would do some engine work and go with a 4 mill? any suggestions?
