hi guys,
just wondering if anyone could help me with deciding on a few things...
i have a 308 5L stroked to 355 with raised compression 9.75:1 forgies, ported heads with bigger intake valves, roller rockers stock ratio, double row timing set in a vr commodore,

just wanting to know what size fuel injectors would be a good upgrade (cc) and what pump would be good, is it worth getting a dual throttle manifold and what else would you recon would be worth doing to the engine to get great power keeping it naturally aspirated.

cheers

Also, just to be pedantic, you had a 304, not a 308.....

if your lookin at forced induction then it might be worth looking at a boost friendly cam and a group A style manifold because it is easier,cheaper and neater to setup for similar power gains

Is the engine running out of fuel now where ever it is? I'd go a cam upgrade as well as injectors and pump.

When Holden changed to the black motor they were all 304's from there. VK on.

i think multi point magna injectors should be ok with what u have a and a walbro intank pump should be heaps, i would definetly go the torque power manifold with the 1000cfm throttle body and if u want have your air cleaner just sticking out the bonnet looks tuff as
