Wow those look amazing! And far less hassle. The only thing I might have a little concern with is loss in horse power. I am building a nitrous motor. I went with a scat rotating assembly, 3.58" stroke crank all forged steal rods and crank , and forged aluminum "icon" pistons. I'm building this one to hopefully 650 to 700 hp with the 200 to 250 nitrous shot, will manifolds still let it breath properly?
