Engine runs great at full throttle on the 3 carbs. I have a lot to learn on these 4-Bangers, as I did not build the engine, nor did I ever have one, much less than work on one. I bought Jim Brierley’s book…4 Banger and Me….and this is a real eye opener on these ‘put aside’ engines. Story goes that the Flathead V8 only started winning meets after the war, and that the 4 Bangers dominated the scene prior to that. If you read the section on this engine in the 1932 Ford Book, it states the engine at 200.5 cu. in. and has more torque that the ’32 V8. Most of the speed equipment was developed for the ‘T’ and the ‘A’, and when the improved ‘B’ and ‘C’ 4 Banger came into being, well, all hell broke loose on modifying this motor. In reading Jim’s book, it really is a shock & eye opener on the performance these engines have. ( 200 mph + at the Salt Flats ) This engine is also bored out .080, the Riley Racing overhead set-up has 2 intake valves / cylinder, the 4 port design allows better air intake, removing the Siamese sharing of two cylinders, the exhaust valve is 1.750, and these engines can rev 5,000 rpm +. Yes, it can put a V8 to shame, as it did in the early days. Jim’s book also mentions that these engines need air…hence, 3 carbs are not a problem. More pics for DD to blow up.
