    Does anyone have any information on any performance that can be done to a Ford inline 6. I have a 223, 300, and the other I think is a 260 as well as a few other displacement 6 cylinder Ford engines. Does anyone have any recipes for a hot inline 6. Which one should I go with. This is going in my 61 unibody. I want to find a T-5 from a mustang to go behind it. What is the best T-5 to go with I want a good overdrive for mileage and a T-5 that is durable. I want to go fro max mileage and still retain some performance. What rearend gear should i go with. What is a hot combo for these Ford 6's What cam, head, pistons, rods etc. are the best. what are brands part numbers etc. Help me out here i know there are some fellow diehard inline six guys out there.

    Thanks

    A good source for info on these engines is on the Inliners forum located at www.inliners.org

    Try fordsix.com or try some Aussie web sites, Ford Australia still build a very strong six.

    May be mistaken but the 300 6 has the same bell housing bolt pattern as a sbf which means it will bolt directly to any T5, AOD, FMX, C4 C5 C6 that was formerly bolted to a 302/351W,
    even SBF flywheels and clutchs can be made to work (will need balancing).

    Also, the 300 six is a decent torquey motor.

    Same bh pattern but I think it is a 164T flywheel and SBF is 157. I ran a Clifford 260 cam and seemed like stock and a PAW 270 which had a slightly lumpy idle. If you run the EFI dual exhaust manifolds you will need an aftermarket intake, but i've run a single 500 2 bbl and dual 500 2 bbls and the engine ran the same as original carb so don't worry there. I did Chevy 1-15/16" valves but not worth the pocket porting trouble. I did have a part throttle ping with 300 distributor and not with 240 distributor. I'm figuring you will go with 26" tires and want to cruise at 2000 with 0.79 OD and you probably have a 3.20:1 so its 2000 RPM at 60 RPM.

    All are Ford 300 sixes. The blower equipped one really gets it on. These are really strong blocks and a great foundation for inline fans. Both of these seldom cross the Finish Line second.

    For the smaller Ford 6's I would recommend getting this book. It was written by a friend of mine and has a ton of info on hopping up the Falcon 6.

    http://www.falcon6handbook.com/

    For the big block (240 and 300) just search the internet. There is a ton of info, speed parts, and other goodies out there to make the 300 one very fast inliner.

    Good Luck.

    You can use the smaller 157 tooth flywheel on a 300 if you find a 1976 Granada bellhousing for a 250 six, casting prefix D6DP. It places the starter motor in the correct location.

    What kind of fuel economy (mpg) can you expect with a hopped up 6 with an od? With gas creaping into the $5 window a hot inline 6 might be nice for a daily! What kind of HP can you expect for one of them blown 300s?

    I had a 300 Ford 6 in a '74 Winnebago motorhome I used to haul my vintage dirt car to races around the 5 state area. It was a little tired when I got it, so I went through it; rings, bearings, a Sig Erson RV grind cam I got from Dale Wilch. I added an Offenhauser 4BBL intake with a 390 CFM holley and exhaust manifolds from a late '90's F150. This was a killer setup; I had a friend who had a Dodge 440 powered motorhome that he used to tow a similar car. I went by him just about every time on the way home. It got 12 mpg unloaded and 8 mpg pulling the trailer and race car.

    The only bad thing s that the brakes were TERRIBLE. I had to plan every stop 15 minutes in advance (yeah, we had brakes on the trailer). A lot of the guys we ran against had 300-6's in their "vintage" race cars. Guess what happened to the motorhome when we didn't need it any more?!?!

    If you like 300 sixes, look at the exhaust manifolds on a late '90's F150. If I didn't know any better, I'd expect to see "Fenton" on them.:)

    I woukd go with the 300. I had one in a '62 unibody stock that ran real well and I understand that they take to modifications real well. I think that the real serious guys use the 260 head to start with.

    You can get a cam from isky or any of the other major cam grinders, I would shoot for low to mid range unless you are racing it. I have seen single 4 intakes for them or you could build your own and put a brace of side drafts on it. SU solex webber any number of large bore motor cycle carbs.
  19. The 223 used to be the hot ticket in local figure-8 racing for years. Some guys might be using them still. There was one local shop that specialized in getting them hopped up pretty well. They had quite a unique sound to them.

    Be careful at the salvage yard, Granada's had a differently balanced flywheel than the Maverick 250... When I was young I had a Granada 6/3 speed and the flywheel was toast... So it was either buy a new one, or find a junkyard one... the repair place found a Maverick flywheel, bolted it on and started it up... Bent the crank.

    Are you saying an out-of-balance flywheel bent the crank? Explain please.

    A 300 needs a neutral (zero) balanced flywheel.

    Will a T-5 form a 302 forma mustang bolt right up to the 300 or do I need an adapter. I assume it is the same being the same small block bolt pattern.
    Thanks

    THIS IS THE BOOK TO GET!!!

    The authors are amazingly knowledgeable about how to squeeze every ounce of power from the Falcon 6's (cam selections, head mods, carb tuning, etc.) I used it to build my tri-power 200 with a T-5 in my '62 Falcon. And the results were awesome!
