I am building my first Flathead and i need help choosing the right camshaft. I am staying really stock as far as heads, intake, and carb go. (Im on a tight budget) Its a 1949 239 8BA, it will be going in a 49 Ford F1. Now the two i have in mind are the MAX1 and Comp cams Thumpr (not the mutha thumpr). Now will i even be able to use a cam like these with a fairly stock build?
those cams should work well with a basically stock flathead...wilder cams sound nice but they need a lightweight aluminum flywheel to rev quickly.....just run dual exhaust and you will be fine...I ran basically the same combo in my 52 F1 for years...I had headers and a Mallory dual point with a Mallory coil,electric fuel pump, and an electric cooling fan....I also had two 97s on an Offy manifold, but it never idled right...so I put the stock intake on and used one 97....ran like a champ for many years like that....then I swapped in a 55 hemi.
Tight budjet I understand, and the ax 1 should be good for a near stock engine, but for God's sake get rid if that stock "Loadamatic" distributor. As far as "seat of the pants" get up and go, this is the biggest single improvement you can make. Check with GMC Bubba. Dave
Over camming is the easiest mistake you can make but the Max 1 should be fine with a near stock setup and it will work if you decide to do a couple mods down the line. I like the Max 1 in my flatty; it's stock bore/stroke but has adjustable lifters, an Edelbrock Superdual, 65cc heads, Red's headers and an HC dual coil.
Thank you for the help I am ordering the max1 cam. As far as the distributor I will at least for now, run the pertronix ignitor 2 kit.
If you run it in the stock distributor, you're wasting your money. Get one of GMC Bubba's distributors...cheap, very good, and work perfectly!
We run the MAX1 in our stock 8BA...works good. We also have a Petronics unit in the stock distributor that also works MUCH better than points, I don't feel it's wasted money although we'd like to upgrade to one of GMC Bubba's units some day. That distributor with the Petronics has gone 18,000 trouble free miles so far.
That stock distributor with a Pertronics unit installed no doubt supplys ample spark to fire the flathead. But the advance system in the post '48 flatheads is a joke. Getting that spark at the right time is almost as important as getting it when it comes to pep and power. Dave
what would you guys recommend for a 50 block bored .040 stock, 4 inch crank, EAB heads, 2 97s, mallory by bubba unit?
