just picked up a complete 300 inch, carburated 6 off craigs list for my chopped 51, looks like will have to recess the firewall, monster motor, anyone dun this before?
You might have to find the original 6 radiator brackets and move the radiator in front of the core support like they did when they came from the factory with a six.
its a big motor, not sure that would even do it, but think it would be super kool with amess of carbs and split manifold. whats kool is the intake and exhaust are on the right side so don't have to mess with going around the steering box
Seems like an awful lot of work for little benefit...a 302 (backed with an AOD if you want) is also plenty of power, and will probably get better mileage than a carb'd 300 six. I guess I just wouldn't cut into the firewall for a 6 cylinder...
I know someone who did,but his had an S10 front clip...cant remember for sure if the firewall was modified but I dont think so.
At one time my wife and I had two identical '88 Ford pickups, except mine had a 300 six and hers the 302, both 5 speeds. In my opinion the six was by far the better engine for a truck application. The 302 was a bit smoother but didn't have the balls of the six. Then again maybe it's just me. I've always preferred a torquey, relaxed feeling engine over a high-revving screamer.
Ran a 300 with a c/4 in the ecdonoline for a while. 350 gear in the rear -was a very quick truck and soo touque--had clifford headers--sounded good too
hey thanks for the comments, i am runnin a 1956 265 in my 50 but thought this would really be kool to run in my 51
sounds like waste of a good car, Flathead V-8 is the way to go but i have no idea what you are using the car for??
The 300 is an excellent truck motor, great for low rpm pulling and durability, I guess it all depends on what your plans for the car are but I would think it to be more practical to go with a V8 for all round cruisin, way more bang for your buck.
I had a offy manifold and a header on one in a ford pu. It will eat 302 off the line. Balance it and up the breathing. Ya might want to put some better oil gear in it if ya wanna shift it past 4000. It beat the rear bearings out of mine. I had 2 1/2 inch mandrel bent exhaust and a 40 series flowmaster. Do the exhaust don't do the flowmaster. On a six it sounds like shit and will rattle your brain on the highway. They pull good and they get good mileage if ya keep your foot out of it. You should have seen the looks on peoples faces coming out of vancouver one night with a complete BBC 396, a 350 longblock,an engine crane and a set of 36 swampers on rims in the back of a short box pu doing 120k on the freeway.
By all means, run that 300. I put a 292" inline Chev. in my '55 Bel Air daily driver a few yrs. ago when the 235" was due for rebuild. Had to make some gearing changes to utilize the torque curve. It's a great road car now. I didn't need to cut the firewall. Moved the rad. ahead of even the "6 cyl. position", did some serious oil pan, pick-up tube, & front cross member mods., but welding gas & rod is pretty cheap.
Im for it ! Take some pictures, I would like to see it. I have a hopped up 226 flathead six in my shoebox, and just scored a rare 254 flat six truck motor from a 50 F6 school bus that is going on the engine stand this weekend......Ive never had a 300, but always wanted to mess with one. You can always relocate the radiator farther to the front by moving the core support...
I think it sounds like a Helluva idea. Certainly the most original engine swap into a shoebox that I've heard of in years. Please let us know how it turns out!
well we're not done with the chop yet but getting close, got the front clip off and it looks like a go with the 300. will post pix when we start.
I only have one consideration that isn't being mentioned: how much does it weigh, and how much of that weight will be ahead of the front wheels?? I had a '50 Ford coupe with a 302 installed far forward (I guess to make it easy to clear the crossmember) and it handled like CRAP and the front bumper dove for the ground every time you hit the brakes. I suspect you may have the same problem with that big six unless you set it back way far into the firewall. I get why some people really like a 6 over a V-8, but in this case it's not just a matter of torque and sound it's also a matter of balance, handling, and safe braking to keep in mind. I don't know what the 300 weighs, but straight sixes generally weigh MORE than a V-8, and in this case the weight would also be much farther forward on the chassis.
Watched a D/MP (I think) 1966 Nova 4 door running a 300 Ford six win its class at the Indy Nationals in 1969! Does this sound blasphemous? Smokey Yunick would say, " An engine doesn't know the name on its valve cover". Consider something else - the 240 and 300 Ford 6's all run a 12 port head right out of the box! Chevy guys spend big bucks to get this on their 230's, 250's and 292's. All domestic inline sixes respond well to increased carburation, headers, and camshaft timing and lift increases. BTW, don't even bother putting down the 300 Ford 6 - the Frenchtown Flyer (Inliners International) will put you in his bad book.
I've ran a 300 in my 55 F-100 for the last twenty years, lots of different changes over the years. There is no Cross flow Head that I know of in the U.S.A how ever. Three different oil pans to chose from, and late FI headers work well. Weight of it is around 600 lbs or so. I replaced a 223 CI, Think it weigh more than the newer 300.
