Is it possible to run one of these engines with 2x carbys what do you do for distributor / vvt . I was thinking twin turbo twin carbys can someone point me in right direction.

Welcome to NICO..!!!!

If you don't mind me asking, why do you want to ditch the electronics? You can make 400-450 HP with 100% stock everything, and then if you want to make bigger power then you can just get different injectors and retune the ECU. The stock ECU is pretty reasonable in terms of tuning, it basically acts like a stand-alone. You kind of hit a brick wall at 450HP because you'll max out the stock MAF and injectors at basically the same time, but theres all kinds of ways around that which are pretty simple.

Thanks for your response I have been down this track before with twin turbo chev autronics all bells and whistles cost big bucks.i have engine only no electrics can you recommend after market ecu and injectors that will support 900hp that are user friendly. My aim is to do this myself.

What all is the engine missing? Is the intake and all the fuel injectors and other sensors/coil packs there? If all you'd have to get is a wiring harness and ECU that wouldn't be too hard.
