Ladies and Gentlemen, Mattliston FTW!block guards are a marketing gimmick
fuck block guards. waste of money
and if you seriously asked if they could be welded in, you obviously saw or heard from a friend about the existence of block guards.
do research yo. do research
I remember his build on 7thgen, he had a built bottom end though did he?we hit 489hp on Andyman97's car on 30 lbs of boost and c16 race gas on stock sleeves on a d17 and we had no problems and everything held together even when he was in 3rd gear at 8000rpms and shifted in to 4th and let out the clutch not knowing it was actually in 2nd. block held up fine just a hone to clean up the sides of the walls and the pistons looked like rolled up balls of tin foil.
so I hope some of that helps
