What guarantee do you have that your built engine isnt going to blow up? None. Just because you install some fancy pistons and rods doesnt mean its not going to blow up. I’ve seen more people go through built motors then guys running stock blocks. Why? Because of assembly. Motors from the factory are built with the proper tolerances and assembly. Very few shops can reproduce that.

Then there’s the whole tuning aspect…shitty tuner and kaboom.

There’s little to argue about the SR’s bottom end. Its incredibly strong and can take a serious beating at 300whp-350whp.
