    Hello Everyone!!!!

    I have been reading various post for last few days....WOW wealth of information.

    Ok here goes, I new here to the forum, Also new to the flathead world...just bought a 48 Ford F1, It has an 8BA in it, as that is what is on the head if this is correct for identification?

    I am a recent graduate of Nashville auto diesel college, Collision repair program, I have always been in love with the classics and rods. I work for one of my instructors at RPM Restoration in Clarksville TN. We also have a full machine shop, however our engine guy is a hit and miss when he is I'm asking for some advice here.

    I'm planning to have the engine rebuilt, and mating it to a GM T-5, here is what I am planning, the 304 C.I Scat stroker kit, L100 cam, Now my question is, can I have the stock heads worked? or which edelbrock or offenhouser heads should I get? What about valves? What about lifters? I am planning on stock intake and carb for now...eventually that will be upgraded as well but on a budget currently. and is there anything else I should consider or need to know?

    Your wasting your money if you plan on running stock intake and carb. I would change intake and heads before investing in a stroker.

    Stroker=big money, cam=still pretty high total, intake and carb=not so much money. I would go heads, intake, carb, and see how she runs. Unless the bottom end is shot anyhow.
  6. First order of business I'd get headers and duals from Reds Headers and a mechanical advance distributor from GMC Bubba here on the Hamb. I've been driving my 48 F-1 with that set up for a few years. Welcome aboard, F-1s are awesome no matter what you do with them

    I went with offy heads and offy regular dual manifold but the super dual is a better performance. I went with two Holley 94s as well. I changed out my stock ignition as well you may want to think about that as a performance improvement.

    I guess I should of stated that I'm looking for a mild to moderate performance build, as the truck is being built into a restomod, Again never had a flathead before, I'm a big block chevy guy and love my Muscle cars and performance...

    I know that flattys are not high horsepower engines....but with just heads intake and carb I don't think that is the performace I'm going to be happy with...but again I don't know jack about flattys
  9. The build you're describing will set you back at least 5-6k and you'll get your doors blown off by a stock 350. Flatheads are cool little motors with a cult following, but not many are taking the checkered flag

    If you are planning on spending that much money, you would be better of with a smaller supercharged engine. I would you suggest you get one of Joe Abbin's books on "Blown Flatheads". If you are used to "Big Block Chevy's and Muscle Cars", any kind of N/A flathead, no matter how big, will really disappoint you, especially in a vehicle as heavy as a '48 F1.

    I by no means expect to be burning up the quarter mile, Just looking for a nice sounding mild performance motor, Cost is a factor as is with anything, but here is what I have found so far....maybe I'm wrong that is why I'm here asking for help/advice

    304 CI Kit $1700.00
    L100 Cam $200.00
    Edelbrock or Offy heads $ 600.00
    ebelbrock Intake $400.00
    carb $350.00
    Gasket kit $75.00
    Headers $300.00
    Machine work and assembly= Couple cases beer
  12. Sorry I wasn't trying to throw a wet blanket on you haha. I've actually got a flathead all rebuilt ready to go in. Mines a milder build. For valves you can actually use small block Chevy valves to save a couple bucks. Lots of info here on the Hamb about springs, etc.

    Similar setup in my '50 with Offy heads and intake, but I have the super dual and 97's. The 94's are great but don't work well on the super dual. I don't remember why, something to do with the choke I think. Uncle Max steered me in the right direction, he'll help you too!

    Go over to the following site and read everything. That will answer 95% of your questions.

    If you need to bore the block, go to 3 5/16. If you want a longer stroke, buy a Merc crank. I would not spend the money on a stroker crank.

    If you want it to be a SBC, buy a SBC. ;) It will never perform like one. You have to like the uniqueness and nostalgia of the flathead to appreciate the idiosyncrasies.

    Unless you have found someone to grind a L-100 cam, it may not be obtainable. If you do know a source for one, please share.

  16. Just save the beer until the build is done...

    another cost is hardware to assemble, the Bubba dist. recommendation I will give a X2, fuel delivery? stock pump or electric? generator or alternator and new mount for either? and probably many other little things you'll run into that I can't think of right now... oh, oil pump, stock or high performance... see what I mean

    lastly, there are many, many, many posts here on building flatheads and many books on how to do it. research now will pay off dividends down the road. take your time and have fun with it. You would probably be better off getting the help you want doing research as stated above and asking specific questions to get clarification, if not you run the risk of having your post end up like this one...

    IMHO.....The best bang for the buck is this combination;

    Bore it, cam it, Reds headers, electronic distributor.
    If you want to got deeper into your bank account:
    heads and intake(2x2, 3x2, 390CFM Holley, or 500 Edelbrock.) Heads are classified by clearance (Offenhauser .425 or .400) or chamber size(Edelbrock 76cc etc.) Be sure the machinist knows what he is doing and be prepared to spend some money. I took a 8BA bored it .080, installed a Isky Max1,Offenhauser .425 heads and intake, Edelbrock 500, Red's headers, Mallory Unilite. I did everything except the machine work and short block assembly. It runs great, but I spent. $4962.83. As you know, for that much you can buy a crate motor and have a little change. Would I do it again? Absolutely...

    You're also gonna need water pumps.
  20. also save that stock manifold and carb and use it for the first 500 miles then bolt on any carb combo you want...
