hello hello i have a 78 f-100 with a 300 in it. i love it and i was thinking of building another one for when i retire that one. the truck has almost 500,000 on it and its on the second motor. anyway i bet a buddy of mine that i could build a 300 to walk down his 302. he has his running in the low 11's. i know it can be done and i know it will cost. but alittle bit here and there wont hurt to bad. if you guys have any advice or part numbers or anything at all please help me out
but you do know that a 300 was not built for speed because of its design i doubt you would beat the v8 unless it started running crappy. just put a cam,headers and intake with a 4 bbl carb and get the head ported and if they make high compression pistons get them too.
The last thing the workers at Ford had in their minds when it was designing the 300 was speed. There is ways that you can do it, but it will cost like crazy.
Actually, Father as a Hoby, use to build 300's as Race motors for friends & could get on average 500hp out of them.
Get a hold of Custom Classic Trucks by Petersen's Publishing Co. & ask for a copy of their Aug. 2001 issue, it has an article in it, starting on pg. 70, describing just exactly how to build 300 I-6 motors to kick some major ****.
So don't listen to these nay sayers, go for it.

Sure, if you have enough money, you can smoke his ars. True, the 300 was not made for performance, but at the same time, it isn't bad for it either. 7 mains, gear drive cam... the biggest drawback is the head. Check out www.autoimagery.com and on the left type in Jerry Arnold, Steve Ambrose, Glen Treadwell, or Mike Nahan. -compliments of fordsix.com, 82f100 and FTF.

Not really, all it requirers is a;
Perfomance Crank
270 -degree Cam,
Header,
Four Bbl. Manifold,
0.060 inch off the head for a 9-10:1 comp. ratio,
After market high performance distrib. & coil,
Doug Fisher vibration damper.
Doing just this will get you an easy 245 hp, for in between 2,700.00-3,400.00, depending on where you go to get the bits & bobs.

By expensive, I meant as compared to a v-8. There is no such thing as an aftermarket or performance crank, unless you have a stock crank machined. So there is whatever it costs to turn, polish, and balance a stock crank. A 268H cam and lifter set would be about $200, then you might as well get springs with that. Header is about 150, a new Offy 4bbl intake is 200 from JC Whitney, although for racing purposes I would use a 3x2, machine costs for milling the head, you'd be far adhead to port at least the exhaust side, I've never seen/heard of a performance distributor for a 300-6 (that doesn't mean there isn't such a thing), and a Fisher damper is 100?
My point is, even after all this work, if you get 245 hp, you stand no chance with an 11 sec. Mustang. You could take all the money it took to get 245 with a 300 and put it in a 302 and get probably 300 or so.
If I can locate a Performance Crank for a '61-'64 262 I-6, one sure as bloody well can be found for a 300 I-6.
I was only showing what the basics could do as listed in Classic Custom Truck article Aug 01 issue pg. 70.
There are & were other things I could have gone into but I did not feel like waisting band width because it is posted else where here.
And those other things Will get it up to 500 hp.
And Just Because You have Never Heard of such things, Does Not Mean It Does Not Exist.
Say Mallory or Purtronics for instance.
You can keep your finnicky pieces of Junque V8's, they will never hold together as well as a Big Block I-6.

Mallory does make a Unilite distributor for the 300. Mine cost me 260.
The mods I did to mine are:Offy 4 bbl intake,600 holley, ported head with 1.92i ntake and 1.6 valves, Erson cam, bored .040 over, Hooker super comp 3 into 1 x 2 headers Mallory unilite dist. Mallory promaster coil and mallory hyfire 4 ignition box. This was all in my 89 f150 with a 5 spd manual.
ford v8's are no where near pieces of junk. what are you whining about. I've never seen/heard of a performance distributor for a 300-6 (that doesn't mean there isn't such a thing) that is what he said and this is what you said, And Just Because You have Never Heard of such things, Does Not Mean It Does Not Exist. read a little and you just keep thinking that an I6 is better than a v8.
For a dyed in the wool I-6 man, You bet your bloody **** they are, so chew on that for a while, boy-o.

and i guess that's why my 91 5.0 HO smokes all sorts of cars and i know for a fact it smokes 300's. i have no problems with it. i just built a 302 with all sorts of performance parts inside and out and i have it in a supercab 83 truck with a c6 and i need a 2400 stall but have no money and it can still beat an I6. it's got power out the ***. you are smoking something why don't you share.
it's been my understanding that in general, the displacement of the engine determines how much power you're going to get out of it with EQUAL modifications. By equal i dont mean both intakes are ported or headers are installed, i mean they flow the same.
The reason a 302 is better for racing is the availability of parts for cheap, and also not so cheap.
take a look at Frenchtown Flyer's 300. now tell me that thing aint fast. There's also 1000hp+ 302 motors out there.
they make all sorts of things for 300's they are just not meant for racing i gues it is because of the straight design or the stroke but i think it is close to the 302 is it or not. anyway i like 300's but i love my v8's
