For daily drivability and reliability go with the LS1, but for raw power and ungodly torque numbers use a 454, or stroke it to 496 while your at it, you will have to invest in allot of suspension and drive line parts to back the big block.

I love bigblock power , but if I had the money and the know how to install an ls1 I would do that .It just seems like you have endless posabilty with the ls1 . You can get good mpg and still hammer though turns .If this was a drag only I go BBC . In the end you will spend about the same .
