I have a 300 with a steel forged crank. I have a friend that works at Wiseco I can get his price for a set of custom ground forged pistons. And a set of 4340 Forged connecting rods. with the rotating assembly Fully balanced. Full roller rockers. bench flown head. Plan on attaching a twin turbo setup. And a tune on the ecu. And a new camshaft.

yes its a lot of work but it will also be different and I like different so I really don't care about the cost its something that will happen overtime so im not paying for everything at once.

it will also have the Rev limiter set to either 6000 or 6500 but don't plan on taking it over 5200 rpms. With a t-56 Wide ratio behind it

Anything is possible I guess but you got a LOT of work to do on that head to get the airflow needed for that kind of power.. this motor only makes 150hp stock because the head is such a massive cork... 300 cubes should make 300hp without even trying hard. Never the less post up some before and after head flow data as it comes in because I don't think anybody has done that for the inline 6 before.

 

That's pretty awesome. Thanks for the link to that. Ill be hoping for a lot more with the modifications I'm doing to mine. Ill Probably need quite a bit of torque for that .5:1 overdrive gear with the 3.55 Final ratio.

 

Ill get the data when i can get to the truck. . I'm moving to MI for a while and cant bring the truck with but im hoping to have enough money to start on it when I get back. plus im broke right now with no job and have to start paying back student loans soon. so it might be a while.

 

You're expecting a lot from that motor, trying to rev it to over 6000. The 300-6 has the benefit of 7 main bearings, but you gotta realize stress goes up exponentially with rpm. So 5500 to 6000 is bad, but 6000 to 6500 is asking for trouble when you're trying to make that kinda horsepower. Even with good rods, I'd keep it under 6k and the thing will probably hold up to any abuse you want.

And why a t56. You can have a stronger trans that bolts up better for less money by getting a tremec t600 or whatever it's called. And as far as the .5 overdrive, it is useless because the truck would have to be on boost to keep the thing moving down the hyway. Unless you have short tires and 410 gears, and a big turbo, it will be on boost driving down the road.

Head work will be helpful. Get it ported and smoothed and if you're keeping efi, custom big port short runner intake, with at least 60lb injectors to start. Personally I'd use megasquirt, but stock ecu and quarterhorse will work great as well.

Twin turbo is not needed. Use what you can get. I say start with either a single powerstroke turbo from 94-97 with a t4 flange. That will allow you to upgrade easy later. The psd puts out about 60lb air which is up to around 450-500 hp. If you're set on twins, locate two hy35 from 5.9 cummins trucks. They put out about 52-55 lb/min each. 100+ lb air is way more than your goal, and the hy turbos have smaller exhaust housing than the hx so it will spool reasonably quick.
I like oem or brand name turbos for quality and longevity. You know that an oem turbo is made for durability. Don't worry if it's not water cooled, a lot of diesel turbos aren't and they go 150-250k without rebuild.

Sounds like you have a good build plan. Start saving and gathering parts. Are you planning on putting it in the 93 truck you listed. I'm guessing it's a 2wd.
Do you plan on racing or just a fun toy.

 

You need to do a lot more research. Also you won't be tuning any factory 300-6 ECU.

You'll likely need to convert it to a Mustang A9L/A9P and do a lot of setting tweaks to convert it to 6-cylinder operation (this is possible with the right tuning software). Either that go aftermarket EFI.

 

I plan on it for the 87. I want to get into racing but still have it streetable. plus itll be nice just to cruise down the interstate to every once in a while. and ya they're both 2wd
