i work at a engineshop, and im building my first ported and relieved 8ba flathead, what i want to turbocharge it and feed it by carburation, for having a challenge... there are not many around here, who know about this type of engine, dont even speak about making it more powerfull. Now do i have to pick my carburator. i had trouble finding out wat kind of carburator i had. i have three 8ba engines to start with. two of them have the 94's and one had a strange shaped carburator. i found out it was a two barrel Lincoln 337cui flathead carb. it looks good for tubocharging because the fuelchamber and everything are all inside the housing. the diameters of the barrels are individual 0.16 inch larger than the 94's, so cfm also is larger than the 94's i assume. im probably going to make my own manifolds (intake and exhaust) so i dont have to have a matching intake. it fits directly on the 8rt manifold so i could use that also if it would work. so what do you guys think i can do? i could find (and pay..) blownthru carbs out of european cars, but i rather use the old/sweet stuff. except for the turbochargers. i want to use the variable turbo's from vw so i have also extra in low rpm. will try different combinations. using the same basics. rossracing pistons 7:1 3 5/16 bore, 3.75 stroke, ported and relieved, chevy stainless 1.5 inch valves and johnson adjustible lifters. i start with the cast iron original heads and the original camshaft. could you discuss your ideas, experiences and opinions with me? i would appriciate it. if you need pictures, i will post them. a eager apprentice
Check out Rodder's Journal # 60 there is a 34 3 window coupe owned by Jack Stirnemann with a twin turbocharged 59AB flathead you may want to try and contact him for information.
I really don't see having any issues with needing original carbs. Since you are going turbo anyway and fabbing up your own stuff, why not go with a Weber setup. Plenty of info out there from people already using them. Flathead is about 4 Liters so it should be pretty easy to scale it from what's already out there.
