build a 347 efi engine

[broncomike86]

I want to build a 347 stroker efi engine. Can I still use my stock efi intake manifold. Will need to replace the stock injectors and throttle body? I'am looking at around the compression ratio 10-1, will I able use 87 oct. fuel on Ford Bronco. What parts work best? I'am looking for 300 hp - 400 hp. Thank You for your help

umm lets see no, no, yes, and no. for the performanc on what u are asking u will need a free flowing intake, bigger injectors for the bigger displacement, bigger throttle body for more air flow. a 10-1 compresson is a big step up so 87 oct will turn into 93 and up oct. also different heads should be used. You will need to do lots of research on these things to get everything working as one. check out fordfuelinjection.com and other ford performance websights to help out. :-B

You will also need to either get the computer reprogrammed or get a whole new computer. Headers, injectors,throttle body, and intake will all have to be replaced to maximize the power from the motor.
