The 1-3/4 should actually help, it gives you some extra torque down low. 1-7/8 is probably overkill for most coyote builds.
Yeah. That's what I read almost everywhere I looked so that's why I got them. I really wanna break 500whp NA but stage 3 cams and install are gonna be expensive so I'll go all the way up till that and then See what I wanna do after. Won't be boosting it but I may spray.
