i want to install a different motor in my 85 z28 i have a carburated 350 in it now but i want more power so i dont know witch motor to choose an ls1 or a 454 witch one would you guys choose and why thanks for your help

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 .

thanks for the info i'll probly go with the ls1
