i dont know why the hell you would want to spend the money on the i-6 to make 5-600 hp. you could make way more power on a 302 v-8 spending that kinda money

You obviously have NO Idea what a 300-6 can do. 500-600 HP COULD be done fairly cheap (cheaper than a 302 can do it for)
Headwork with big valves, a good cam, STOCK forged HD crank, STOCK rods, and good forged pistons for a solid bottom end that would support 500-600hp. That setup alone would make ~275hp ~350tq (say about 1500$, but I build mine cheaper than that) Now get a T04B turbo and run 15psi boost and your at 550+HP and 700+ft-lbs torque, for another ~500$. If a person did all the work themselves you COULD build a 500HP 300-6 for UNDER 3000$

I'm talking 550hp @ 5000rpm or less (easy with a turbo setup) is Not useless in a truck. I use my 300-6 up to 5000rpm when I'm playing in the mud it allows me to stay in the same gear with a manual tranny. It wouldn't be the best for pulling a load due to all the extra heat it would be making But would have a flat torque curve from ~1500-4500rpm which is perfect for a truck.

well if you think so...but with the same steps you described to your 300-6 you could easly have a stronger and quicker 302. you should also consider what else it takes to support 15psi out of that turbo, you cant just slap it on and expect it to run right for $500, unless you have masterd the art of ****** rigging and skipped the intercooler, injecters,etc.....still seems to be pointless to me

I KNOW what else is needed, That why my bottom line was 3000$ instead of the 2000$ that my costs added up to. Powerstroke intercooler, Bigger MAF, Fuelpump, and Injectors can be had for under 1000$. I've built (and tuned) Several EFI supercharged Cars, Turbocharging isn't that difficult either. Its acutally pretty easy on an INLINE SIX since they have tons of extra room in the engine compartment. In a truck application a 300-6 is a BETTER option then a 302, In a lighter vehical like a mustang a 302 is a better option since its damn near impossable to fit a 300-6 under the hood.

550 hp from a 300 at 5000 rpm or less? I would love to see that. That would entail taking a 300 that made about 250 hp naturally aspirated and sticking about 20 psi to it. That should make an authoritative boom. If you want that kind of power you need a V8. There is no way a 300 is going to do that reliably for $3k, nor will a 302. The 302 will do it for a lot less than the 300 just because the parts are readily available off the shelf. You can only flow so much air throught 6 sets of valves, there's no way around that.
I would like to see an itemized list of how a 300 could be built to do that for $3k. The nearly stock rebuild I've been planning on mine is rougly $2k for parts and machine work. $1k isn't enough extra to buy a turbo and all the necessary upgrade parts to make it work properly.

I've helped build a ford OHV 3.8L V6 with a turbo that made 310RWHP/370RWTQ with only 11psi using stock unported heads, Thats 375hp/400tq at the crank with an engine thats down 68cubic inches on a 300-6.

Oops, almost forgot. BigBlockCapri460 has a turbo on his 4.9. I believe it made 273 rwhp and 414 rwtq on race gas at 11psi. That's about 330 hp and 500 ft-lbs at the flywheel. He did all the work himself and I think he said he has $1500 invested using used parts. 600hp/700ft-lbs is a lot farther away than an additional $1500 will get you.

I know that i'm not quite as knowledgable or experienced as some of you, but did anyone think of going to any companies that make Turbos for import/compact/tuners? They deal with smaller engines and turbos. As well, did anyone consider using a turbo from a Toyota Supra, it has an inline six? I know that there is more to it than that. But it maybe worth a try.

hey silver streak, go open up the bottem of a 300-6,what do you see? 7 main bearings (more crank support than any v-8) , and some absolutly huge rods, the bottem end of a 300 is virtually bullitproof,a 300-6 could handle that with polished rods and one hell of a balance-blueprint job, although it would need the forged pistons
