Advice on Engine...
i'm getting a new procharger so i'm new to forced induction

Any way i've been making my own research on a good motor so after searching and reading, I've decided either to go with 347 Ci or a 370 ci. my aim is to reach 680+ rwhp with a D1.
so I need advices about which one should I decide also with a good budget

also i'm currently running a VRX3 cam: 226/228 .585/.588 113+3 LSA
should I keep this cam or change it to a bigger one ?
last quesion
if I wanna go over 680 rwhp what heads should be getting?Thanks in advance
D1SC (if it was me i'd go with F1A) from EPP with FMIC with fule system.
the car should get 680rwhp+ with 14psi on pump gas maybe add METH kit since Kuwait is freakin Hot like Jeddah..

Good luck man.
Depending on the inches and the heads, our cam may work great with it. Its on the large side for a daily driver, but some people like it.
Ive seen results similar to the cam you have, it works pretty well. For a smallish daily cam a 226/230 113 would work great with a blower. I would honestly not change it up, since you already have it.
Depending on the inches you go with, a set of heads can range from $1300 to $3000. For budget head, check out the PRC 2.5 head. For a higher end head, check out the AFR 205 (depending on inches), or the trickflow heads. Both a solid winner.
Either way, a better head will really shine when your going max power.
And dont forget a 3.70 blower pulley
