    How much power can the bottom end take assuming ARP fasteners used?

    There's a buildup, dyno run video on a 300 six on Power Nation. Impressive numbers for sure.

    My avatar car makes about 550 HP at the crank. Has run 9.00 @ 147 mph quarters. It has a forged crank, crossflow head, billet rods and forged 13.4:1pistons. I've raced the same combo for years, limiting the revs to 7000 RPM.

    Another less radical RPU drag truck I have has a stock bottom end but with a big valve head and 10:1 compression. We limit that engine to 5500 RPMs and have almost 1400 passes on it without failure.

    Are you planning a build for the street or for some type of competition?

    www.fordsix.com has all the info you'll need.

    I was going to say, Frenchtownflyer is your man. I never did dyno runs but I had a 300 six with 4.88 lift cam , duals , Offenhauser intake and 390 cfm Holley .

    Thank you for the website, just joined. Thinking of using a 300 six in a 23 T altered, just to be different.

    A sleeper would be nice, possibly my Falcon. I'd like it to embarrass these dodge chargers and the like that act all tough when they pass my other Ford POS.

    The 250-300 sixes are quite a bit longer and taller than the 170-200 sixes. Not sure how you could squeeze one in an early Falcon.

    Rule #1: There is ALWAYS someone faster than you. This is why you don't wrestle with pigs in the mud. At some point you realize the pig likes it.

    That said, building a fast and powerful 300 follows the same rules as any other engine. You need to get more air and more fuel into it during each stroke. One of the most efficient ways to do that is with a turbo. 300's respond very well to forced induction.

    I'll check out that vid when my highspeed data is better! Wouldn't nitrous be more efficient than any mechanical power adder?

    When I worked as a mechanic at a dairy in the mid '70's all of the DIVCO milk trucks had been converted to 300 6's. The delivery drivers could break almost anything but not the 300. Good engines.

    This would be a fantastic engine in 57-60 F-100. I like it!

    The 250 is part of the 144/170/200 small six family, albeit with a taller deck to accommodate a longer stroke crankshaft.

    The junior brother to the 300 is the 240. The large six has a greater bore spacing than tha small six family, so it’s longer.

    Before I had six cylinder altereds I had a '64 Falcon Sprint I put a 240 big six in with a 4-speed toploader. I think I moved the radiator in front of the horse collar. My favorite targets were '60s Corvettes.
    A V8 has its accessories mounted ahead of the heads. An inline six has the accessories mounted on the side of the heads.

    No, I unfortunately do not think so. But it was a really bare bones build up - head work, flat tappet cam, 600 4V carb on an Offy intake and headers. Oh, and a straight axle. I was unemployed at the time of the build and the entire investment in the engine was $700. The secret sauce was I used lots of fiberglass - front end, doors, deck lid, bumpers. It weighed 2510 lbs with me in it. That car cemented my desire to run Ford sixes for the rest of my life. The altereds came later, when I was more financially sound.

    I been looking at them Clifford dual setups. Comp has what seems to be a decent "street/strip" cam kit. Schneider has some fairly wicked cams too. I would think the heads would be the real limiting factor to these engine. I know Promaxx makes a decent CNC iron head. I've heard of these aluminum cross flow jobs, but they don't seem to exist. Not in the commercial market anyhow. Should I even be concerned about the head for a street build?

    It has been done, but it requires MAJOR surgery to the firewall, and the hood.

    Yup. I have a 200 in my '60.

    If I want to take my fan off, the radiator has to be removed first. It's that tight.

    I absolutely love the 2 x 2 Clifford for street and street/strip applications and think it has advantages over a 4V. The Autolite2V carb is vastly superior to other popular brands for several reasons and they are a fraction of the cost.
    Don't rule out making your own multi carb intake either.
    I am not convinced the Promaxx head is superior to Ford castings. I think a rebuilt Ford head will do just fine. The pre '87 head or the 240 head would be good choices for your build.

    In addition to the Falcon, I raced a 300 Pinto built by my friend Pete with my help. pinto2.jpg
    Did you notice the cowl section on the Pinto was disappeared to make room for the big six? It was added on to the back of the hood.
