I have lost my stock block 4 months ago due to not doing thing the right way a far as procedure wise. I put a kenne bell on my stock block at 10 lbs of boost. Big mistake. I shot 3 rods out of 3 different locations in my block. I was devastated. Decided to go smarter and stronger. Now i just got my car back from my buddies garage with a New Longblock 900 SE forged internals, stage 2 ported heads, stage 3 blower cams, Magnaflow exhaust, BBK shorty headers, 2.1L Big Bore Kenne Bell Blower with 15 Lb pulley and upgraded 8-Rib Pulley system. My goal is around 550 to 600rwhp. I am stuck on what size fuel injectors to go with and if i need to upgrade my fuel pump? I have the kenne bell boost-a-pump with my stock fuel pump. I would also need a base tune or if not a good tune as well. any ideas where to get this done too? I am in covina So. California. Need Ideas. Thanks Everyone.
