300 I6

choped84 · Nov 9, 2007

has any body attempted to put a ford 300 I6 into a bronco II. I did some measuring and I think if i move the radiator to the back there will be room. it will be strictly for mud racing and will not be driven on the road.

Yes. It's been done twice that I know of. I never saw evidence of the trucks actually running afterward, but I assume they did.

But the 300 has no power and for mud, you need power. A 302/5.0 is easier to fit and can make a lot more power. If you were rock crawling I would say, yeah, the 300 runs damn good at low rpms and would be a good choice.

I was thinking a I6 so I could stay in a 4&6 class in the local mud bogs. I've had my bronco II for two weeks and the 2.8 is gutless. I'm running stock gears and no lift with 35's. but i have a d44 ttb and a 9" with 4.88's sitting in my yard. I forgot I have an auto trany

I think you would do as well with a 4.0 V6 and it's an easy swap. Mechanically, it goes right in.

An old carbed 300-6 was something like 120hp and 220ft#. An EFI 300-6 was 145hp and 265ft# I think. The 4.0 is 160hp and 225ft#. With just 4.10 gears on mine I had no trouble getting the tires going with 35" Hawgs in mud halfway up the doors.

Yeah, the 4.0 is a good idea, and easier swap.

Here's a couple of pictures i copied and found on my old computer. Looks like he finished it. Never heard of it after so I don't know anything about it.

hhhmmm.....i have a rebuilt 300 taking up space on the shop floor.......maybe someday...

you can put intake headers and bigger carb on a 300 and it would be a VERY stout motor for a 6

thanks for the input, i'm leaning towards a 4.0 now because its lighter than the 300 and theres more info for swaping in a 4.0

There are several 300's in the Mud bogs here. I've also seen a N.A. 300 do a 1/4 mile in the 7's at Mid-michigan, Rail chassis, Mech F.I. Strangest sounding rail I've ever heard.
We also have a 300 powered BII in our crew. It uses a cut down 1/2 ton chassis.
I'm not a big fan of the cologne engines but, It would be much easier to put the 4.0 in.
There are more high-performance parts available for the 300 and they are cheaper.
I wish they had a 4/6 cyl class here! I would win every time I ran. I've never been beaten by a 6 in the Mutant pony.

go to fordsix.com.....an stout running 300 Inline would clean up in a class like that. Alot more torque then the 4.0....just gotta get it to spin.

The 300 runs outta steam at 3500rpm....but with some higher ratio gears in the axles, you can carry more wheel speed and keep the 300 happy at the lwoer rpms....so you get the best of both worlds.

later,
Dustin

thanks for all the help. I'm tired of all the Toyota's winning.

HUH???

... they put 240/300's in TRACTORS...plenty of power...

when I did my swap it was the sweetest of them all...much better than the 302 and 351W swaps I did..unstopable.. :3gears:

truck ran all that summer till I needed the engine for my towrig/dd... :bawling:

as far as a direct swap....NO WAY...3in bodylift still needed a firewall made...but it can be done...

if I had a non 4.0 RBV and wanted more power...just swap the 4.0 in it...not much less power than a stock 5.0..and easier to get to fit..less hassle!! and they WILL take a beating!!

Wanderer, that is torque that you are talking about. Tractor motors are torque motors and so are 300's. So yes a 300 would make a good tractor motor. That is why Will said it would make a good rock crawler.
For drag racing (even in the mud) you need horse power. A 302 will beat a 300 in the mud drags. In drag racing is the ONLY time a 302 has an edge on a 300. Of course as with anything else, A well built 300 will out h.p. a badly built 302.
