A 351 will easily outpower a 300/6 towing. 302 is possible to beat towing but not on acceleration w/o some heavy mods. The reason everyone is building V-8s is because it's easier/cheaper/more powerful. The EFI version of the 300/6 makes about 160hp at 3400 and 260ft-lbs of torque at 2000. The 351, 210hp and 300-310 or so ft-lbs of torque. The 302 is 205hp and 270ft-lbs, but hasn't got much low end torque.

Swapping to the V8 is going to be much easier than finding hi-po parts for that 6, I know I tried. You will never be able to catch up to the TQ and HP of a 351. Even if you could, all you would have to do to the v8 is stroke it and there is no way the 6 could match that output.

One thing to remember, the reason that everyone loves that 6 is the reliability, drivability and longevity of the motor. Hopping it up is going to change that quick! Putting NOS or a supercharger without upgrading the valvetrain and pistons could cause the 6 to tire out pretty quick. And for the price of the supercharger or all the hi-po internals, you can put in a 351 with some hi-po goodies.

If money is a concern, buy a complete 351 from a junkyard with the EFI and computer. I did. Absolutely no regrets!! You can find a low mileage 351 for under $1000 with a radiator and computer. There are a few small things that will nickel and dime you, but total I spent around $1800-2000, and then sold the six that was in it for $700. So for around $1100-1300 you can get a V8 with more HP/TQ and have a lot of room for improvement. That price included headers, a tach swap, four core radiator, electric fan, and dual exhausts. That is a lot cheaper than trying to work the head on that 6 and swap it to Mass Air.

It would be nice to have a 6 that beats on a v8. And if you had unlimited funds, you could. But at the sacrifice of reliablity.

sorry about that. Computer hiccup.

Didn't you tell Whittey in another thread that your 300 was in good shape and not broken? Sounds to me like someone wasn't beating it hard enough...
My 300 would hand 5.0 'Stangs their *** on a platter... Mind you, it did have 230 RWHP at 4500 rpm and 330 RWFT/LBS @ 2000-2500 rpm, and had more potential due to still running a stock 1bbl carb and intake, and it was only a 3500 LB truck... The solution for the factory EFI is to scrap the stock computer and go aftermarket, say SDS or Electromotive. Then a pair of 2.2L Chrysler turbochargers and around 7 psi of boost, and, you'll be pushin a good amount of power, even with an otherwise stock engine...
In my case, the 245 HP and 385 FT/LB factory ratings of the 460 just don't make up for the fuel mileage, and, it's a good 300 LBS heavier than the 300, so, once I fix the 300(had an oil pump failure) it's going to be taking up residence in the nose of the F250... It's gonna cost less to re-do the bottom end of the 300 than get the 460 running right and it'll get better gas mileage to boot...

However, with that kind of budjet, the 351W swap is the most cost effective way to go, It's pretty much a drop in, and, can be done for alot less than that. It's expensive to build a 300 to a point, once past that, it's the same or less than a V8, mainly because alot of V8 parts fit and you usually need 4 less of them...The 300 is an engine you build yourself, and not one that can you can build out of a catalog, it takes a large investment of your time and effort to do it without costing a fortune though.

u know what i say u do. is go wit the 300 but i dont know if u are gonna be able to keep it efi.people dont expect them to be bad *** that would be my motavation .but i dont have a 300 i have a 351

 

[updated:LAST EDITED ON 15-Oct-02 AT 00:44 AM (EST)]there used to be a guy that ran a 300 six at our local track in a early 80's ford f150 4X4. He had nothing real exotic on it and yet he still kicked alot of A$$. The bottom end was heavily preped(balanced, blueprinted)so it would take more rpm and he upgraded the pistons for more compression. He also ran a an offenhouser intake and I think he also had some head work done to it too. Nothing major, all stuff he could do himself. He could run mid 15's in this truck which was enough to blow away the stock V8's in any truck. he also used this truck as a daily driver, so it can be done rather cheaply if you know what your doing.

 

I like the idea of building a 300 because 1. It's original and 2. It's interesting. Everybody builds a V8. Many of them do it with "power packages", and it's plain to see that they have no originality. They may not even know why the part combinations are what they are. People climb Mt. Everest because it's hard to do, but they always go up the easy side. It completely defeats the point!
When my 300 is done I'll have all the power I could possibly justify desiring, I'll get some attention for doing it the hard way, I'll have learned a few things, and I'll be happy about it all.

Not all who wander are lost.

 

Right on!

The world does not have enough truly original people in it. Anybody can build what everyone else has. It takes real skill to go down the other path.

Happy Wandering

 

We all understand the importance of being original and doing what you want, but we're basically pointing out IT CAN BE DONE but it's going to be a long/hard/really expensive road. If you want to travel it, then and I wish you all the luck and i'll be jealous of you when you're done. I had an I-6 and wanted to put some power to it but decided it was to much money. It's just that we're warning you thats all, and pointing out things you might not realise right away. I also like to be original and have something no one else has, but there is also another reason why so many people build up V-8s, it's because people like them for their power and sound. Not just because they are easy to build and cheap, although that is a good reason. To me, and many people, nothing beats the sound of a V-8. The I-6 sounds nice, and is different, but it's a different breed of engine and it's not for everyone. The way it's designed is not to be a power house, so therefore many people don't hop them up, and since no one does, there isn't a large demand for parts so companies don't make them like they do for V-8s. The demand for V-8s got that way because people like it. Simple as that. I'm not trying to discourage you or be offensive, i'm just trying to point out that, it would be great to have a speedy I-6 smoke a V-8, but when do you look at the cost and say to yourself, is a few thousand dollars worth this "bragging" right to me? Is all this work worth the effort? Only you can decide. Good luck and happy motoring.

You do make a nice sound argument. Then again if you follow it out far enough we oughta get small block chevys. If I have my wife's v-6 car apart it's gonna get improved. Regardless of whether or not it's economically desirable. Some people make that choice, some do not. Whether a person does or not is not a reflection upon them. But reflects what they hold important. Whether it's the goal or the journey.

Hail the joureneyer, he will show you the way.
