I have decided that I want to build a turbo 351 to put in my fox.
my end goal is 550-600rwhp, but initially I would be happy with about 350.
what would be the best H/C/I combo for an engine like this? this is my first time dabbling with forced induction. I am still learning what parts are compatible with it.

Are you going EFI or blow though carb? And how much boost are you planning on running?.....I dont have any answers for you, but i know thats what your going to get asked

500-600 rwhp turbo set up would be easaly obtainable with 306 cubic inches, of course a stock block may not like that for too long. for those numbers a four bolt would suit uoy better. in all honesty if you would be happy with 350, that can be easily obtained with a good hci, no forced induction nessecary. a procharger will get yopu there and a turbo would defiantly surpass the 350 on a 5.0 litre block.

i like the idea of a turbo 351W based motor. I would say run twin t3/t4's at low boost and call it a day at 400rhwp at low rpm!!! Get those litttle guys to spin up real quick...perhaps a front mount. Build a good balanced rotating assembly, throw some decent heads (AFR 185's) on there with a custom cam, and 5.8L intake. Keep a real conservative tune on it and i wouldnt be surprised to see a real reliable EFI 351w that puts down big TQ numbers but still gets good mileage and is daily driveable.

that's pretty much what I am looking to build. run a lo psi for daily driving like 4-6psi and crank it up come race day. will the stock internals be ok under boost?
I just cant seem to find very much info on a boosted 5.8 build.
