The Ford Barn - View Single Post - I'd like to start a new thread on the components used in building a flathad

Yes a stock flathead is a very good running engine, however, some want alittle more from it. I like the 2GC upgrade, however you need to bore the intake ports under the carb to match the throttle bores. Just bell mouthing won't do much. Also the stock distributor won't work with this setup. The best distributor up grade is the converted GM unit.. But the crab will work just fine in the earlier blocks.
A.060" bore will give you 248ci and a 1/2 point increase in CR. By angle milling the head yo can add another point and with the 2GC carb allot of torque, and much better fuel mileage.
I'd like a survey her what's the price for boring the block and fitting the pistons. Also milling the heads in your area,.
