Nitesaber, I'm not trying to be a @ss or anything but, this is my thread, I started it to get help on how to build a indestructable, pulling motor, that's still capable of DD demands. If you have something to add to MY topic then go right ahead, if you want to find out how to race with YOUR truck, the start a thread for YOU.

Both Pop & I have "carburetted" I-6's
But, the fuel injected newer ones including our old ones have got to be
the toughest engine Ford has ever built! "Sure, I wish I had a larger v8
sometimes" when towing! But a better low torque "stump-puller" has not
been invented yet, IMHO! Pop is nearing 300k miles on his gently used
truck, & my truck went 289k miles towing heavy trailers before it threw
a rod! (It still ran on 5 cylinders)...but I chose to have her towed home
for a new engine install! (If I had to choose a vehicle to to get me home...
it would be an old Ford or a Toyota)!

I'm thinking. EFI manifolds, stock style "log" intake, new bearings, comp cams 260, a half decent P and P on the head, new gaskets, maybe rings if need be, and a single barrel carb of some sort

IMO, how can you rebuild an engine w/o putting in new rings?

I don't think you can really... I have been taking graduation test all week... My brain is fried...
I don't know if I'll do cam or not, the stock 300 is great on its own... I may just do a stock rebuild, I'm mainly looking for down low power and enough power to do 65-70 mph... I honestly could care less about speed for this truck...

truck! My Toyota Camry, (1990) "with it,s overbored engine as well"! Will
hit 0 to 60 faster than my truck! The I-6 was a racing engine "in it's day
with ford Torinos", But, it became an industrial engine & the 302 v8 took
over!

The thing about flow is that it is really more important as the rpms increase. My other truck really came alive after about 2000 RPMS. The problem is that with my driving style, I hardly ever go above 3000. The stock engine does that just fine

I have re-thought my previous thinking... I'm thinking just a base stock rebuild, EFI manis (just so I can run duel exhaust), and a good electric choke carb that is reliable. Any sugestions on what carb?

Inline 6, (It still has to propel it,s massive weight) when mounted in a

The 300-I6 has always been built off the platform of a inline 6 tractor engine... Made for work, not play.
As for the carb... Are you going with a stock manifold or a aftermarket like the Offey DP? I will tell you right now the stock manifold starved the outside (front and rear) cylinders of fuel and air. A Offey DP does a much better job delivering the fuel and air evenly to all cylinders. That being said I think some have gone a little overboard on carb size for their aftermarket intake. There are tons of guys like me that are going to run the smaller Holley 4160 (390crm)... I think the 4160 in the 600 cfm is ok to but a little big for feeding our I6's. But that is just my 2cents.
PS: check out www.crazedlist.org and once you get yourself set up on there you can search your surrounding area for an Offenhauser Dual Plane and carb. I found mine in MN and I am in IA. I got both my intake and carb to my door for under $200. You could probably do the same or look on ebay for one.

With your application i would still do a minor cam, and when you rebuild go with better rings for sure, and do a bore to clean it out before you add the cam, that will give you a large difference other than opening it up with a new carb.
