You are correct in the engine was a 250/240 - 6 In the cars and some trucks. The 300-6 was around for a long time in industrial/racing applications before being offered in the trucks in the early 80's.

Weighting in at like twice a Jeeps weight, I'd doubt it could "pull a Jeep around like nothing". C'mon now.

Yes, it could. Peak numbers don't tell the whole story of an engine, and the 300 in my '81 E150 pulled just as stong as the 4.0 in my '02 Wrangler. The van was much heavier than the Wrangler.

people were outraged and demanded a V8, so in 1975 ford offered a very choked down and under powered 302 4.9L V8. i think it was rated at 150 HP.

yes I know a lot about mustang II's, this was my first car and i still have it this day, 24 years later!

i have also had 8 other of these cars, personal favorite was a 1978 T top factory V8 car, restored it for the X wife, cought her and my X best friend doing each other in his truck at the end of my street, needless to say i sold the car less then 3 months later.
I'm glad that you can read, I was admitting to the existance of Mustang II's. You know, the bastards that carry the Mustang name, but aren't pure enough to be a full-breed?

300 HP is actually quite easy out of a 300. And reliable. If you are really serious I still have a heavily massaged head,aluminum 4bbl intake(OFFY) Cam and headers. I think I may even have the NOS plate and solenoids somewhere.
I think I'm going to need to re-enlist for this project.

the last time my 78 mustang was at milan dragway it ran 12.19 at 110 mph. this was however in 1999 lol.

some day it will see the light of day again.

and a side note my son (daniel) may have been made in the back seat.

he just turned 21 last month.

Unless you want to knock the firewall out you would never stuff a 300 six in a Mustang two.

I've have several of these motors over the years and for the most part were pretty reliable. I did buy a 1992 F150 brand new with the 300 in it and it was somewhat of a turd. The first engine developed a main bearing rattle during start up at about 1000 miles. This motor made it to about 2400 miles before it rattled so bad the dealer finally said I have a problem and changed the engine. The next engine made it alittle farther but started rattling at start up and hard acceleration at about 10k miles. I drove the truck until it had about 17k miles on it then I traded it in because it was such a hunk of shit. The engine was hammering itself to death and the mileage went from about 21 hwy to 12-13 on a good day. The truck had other issues like bugs trapped in the paint on the roof ( I swear to God ), a death wobble under heavy braking, and other little things that added to me not liking the truck. My 1992 F150 was the first and last brand new vehicle I will ever buy. I traded the truck in less than a year after I bought it for a four year old Grand Am SE with a 2.5 Tech 4 motor in it. I bought the car with 50k on the clock and drove it 100k almost exactly before selling it. The only things I did to the car the whole time I owed it were brakes, oil and filter changes, and a couple of thermostats.

I replaced one in my truck. First one blew up due to failed oil pump. The one I put in had 7500 miles on it. Should last for a while.
They are heavy. I think I remember they are around 500lbs bare.
The motor would pull the jeep around fine, but dont know if the jeep would like having something that heavy in it. They are tall too, compared to the 4.0. Especially if you go w/ a FI one.

the 300 was avaialble since early 70's...
my '66 f100 was available with a 300. infact i put a re-man one in after blowin up the 240 at like 250,000
taken from an old for truck site:
For ’65, two new seven-main bearing six-cylinder engines debuted, the 240ci six, which took over from the 223 as the base engine, and the now-legendary 300ci six, which became an intermediate choice between the base 240ci and the V8 option. The 300ci soldiered on for another 30 years and has legions of fans.

I got an Offy C-series intake on mine and swapped to the EFI dual outlet manifolds found on EFI equipped 300s...
I also put on GM TBI and it runs real good..nice increase in power and it revs to 4800rpm

hmm never had that problem, even on teh stock engine I've buried teh needle on the tach a few times.

The biggest gains I noticed were going to a hedder and cam swap, but still not enough torque.

I had the stock feedback BS carb on there before and I know it wouldn't rev as high as it does now...maybe the 1bbl carter revs higher?


Biggest bang for your buck - higher ratio rockers

It makes a great solid motor but you can only push it so much.

Yea i Had teh TFI setup with Feedback carb (it's a carter also), after I found out the harness was junk, I pulled it all and did the DSII swap. Got rid of a box of wiring and emissions crap. Horrible design that you can't get parts for or they are way overpriced.


forgot to mention on the rockers I thought you had to have screw in studs, or was that for putting on cheebie rockers to increase the ratio? I thought there was some for the 6 out there but pricey? I can't keep everythign straight anymore that has been so many advancements for it and poncho v8s in the past few years, both my 2 favs to work on.

I even picked up a little power and a few mpg's after that swap. Now I need to take some time to tune the carb I have, since I have the metering rod too low, it runs a little lean.

Yeah you have to have screw in studs but you can swap to an older style head I believe...Yes the higher ratio ones are actually chebbie

For my setup I'm still using the TFI coil, DSII distributor and a GM 7 pin ignition module..The ECM is controlling the timing and the knock sensor is installled in the fuel pump block off plate...It was a pretty simple swap and I don't have much money into it and I really like it..

I know for sure 300's were around in the 70's I think they were even around in the 60's. I had a few II's I liked the little v6's I had another one with a mild 302 but it was kinda hairy.
