Now I have my daily driver LSVTEC and I best to hell B20Z block out of the car. Now I know what everyone says about the B20 and it's walls. But there are only 80% of the motors that are bad and honestly I think I have one of the 20% because I drove with this block in my car at 4700rpms for 1500miles straight and allways reved to 8900RPM Burnouts blah blah and never a problem. So B20 or LS ? I want the B20 cause it's out of the car.
