Re: Amazing flathead!!
Most of the recent builders of EFI set ups put the injector rails in there. The tuned port system takes some engineering no mater what type of engine it is designed for and flatheads are way different than most. The horse power claim isn't too unbelievable from the look of the design. A guy just has to know what else he has in the engine to get to that figure. At least it don't sound like total BS like some claims I've heard over the years.

Re: Amazing flathead!!
Thanks for the kind words, fellas. As somebody has already said, I didn't build that EFI setup to impress people, just to make my engine run better. If some people like it then that's a bonus. I don't know who you all are but I recognise and respect Ol' Ron for what he's done and written about flathead Fords so I'm especially pleased he likes it. Henry Floored obviously knows a thing or two about engines as he's correctly deduced some of my thinking behind the design just by looking at the pictures. He understands that things like port length and injector placement are governed by engineering imperatives and not by aesthetics. If anyone is interested in reading more about it they can look up some posts I made a few years ago in a thread called Flathead Fuel Injection on the HAMB.

All factory EFI engines have their injectors squirting at the backs of the valves and, as others on this thread have said, for a good reason. It's where they work best. It's also important for good low-speed running that the fuel is injected at the right time. This is especially important on a flathead V8 because the valve is not at the lowest point in the port, unlike OHV engines. That's why I went for multi-point sequential injection and not for some half-arsed throttle body injection. I can easily adjust my injection timing (and all other tuning, for that matter) with a few key strokes on the laptop and I've found it makes a BIG difference to idle quality. Injecting the fuel about 40 degrees past TDC on the intake stroke seems to work best. At higher speeds, say, over 1500rpm, injection timing doesn't seem to matter. I can assure Russ/40 that putting the injectors under the manifold was not a waste of time and I enjoy the benefits of it every day. It has nothing to do with appearance |

Re: Amazing flathead!!
Welcome Allan. I've seen your 36 in the mags, now it's great to have you here. I'm a Ch-Ch guy myself (founded the Pegasus Bay Rod Club - now a drag club, in 1967).
