I'm rather new to this site, but have ventured over from C5. I am currently in a dilemma to choose a short block for my vehicle. I am looking at a 429lsx or a 419Lsa both built by livernois. I mentioned the LSA because I have been given an awesome deal on the block. I currently have tsp 255cc 6 bolt heads, a Century 4l80, 9" rear with 3.55 gear. I don't see myself going stupid with horsepower, but would like to run consistent 9s without issue. Any help with this decision would be greatly appreciated.
