Why would someone do this?
I drove out to Bonneville yesterday and among the many curiosities was this one. Any idea what's going on with the cylinder heads and intake? It's half a flathead, sort of.

Re: Why would someone do this?
Trying to make a class. 4 cyl streamliner? Saw a rig once with a spark plug mounted on the firewall. Disconnected one cylinger to fit in a class.

Re: Why would someone do this?
Yup,
Four cylinder record. If you look, the intake only goes to the hemi head, the "flathead" side is just a blanking plate. The plugs are installed in this dead side to "waste" the spark. Just pulling plug leads would have sparks doing al sorts of trouble in the ignition. Interesting setup. What speed it run? Martin. |

Re: Why would someone do this?
Dang, I don't know all the reasons, but hats off for some outside of the box thinking. What class did that car run in and any idea on it's speed/time?

Re: Why would someone do this?
Here is the other side. I don't know what class or speed. I was too busy taking in the sights and sniffing the nitro to track any numbers.

Re: Why would someone do this?
Probably no rods or pistons on the blank side.... Very interesting.
We've all seen the video of a flathead running with one head off. Kind of the same idea here.

Re: Why would someone do this?
Jason/TX, Wouldn't eliminating a complete side bank of pistons and rods cause balancing nightmares?
I suppose anything can be fixed with enough bob weights and/or holes/relieving. But I still have to imagine there would be major hurdles to overcome in balancing only one bank of an engine.. |

Re: Why would someone do this?
I would think keeping 8 pistons and 8 rods and having 8 working spark plugs would classify you as an 8 cylinder.
If the spark plugs were not firing, I would think you would be fighting the compression of 4 dead cylinders. The crank may have been reworked to have a similar balance as a Model A/B 4 cylinder.... with the other 4 holes just handing out there. I'm not sure though as I'm just looking at this photo with no other info. Quote:

Re: Why would someone do this?
When I was in the USAF in Germany back in 1963-64 one of the guys on base drove
a 49 Chev in line 6cyl. One of the rod bearings failed so he removed that rod and piston as well as two others to sorta balance things out. He also removed the valve push rods so the valves stayed closed. It ran just as fast, just took a little longer to get up to speed. Wouldn't the flat head work the same as the Chev, no rods, pistons, valve lifters, etc? |

Re: Why would someone do this?
I wouldn't assume it's a flathead block. Very likely has a custom crank.

Re: Why would someone do this?
Don't look like a Flathead block, it's all different. Ignition placement, shape of the back of the block, head bolt pattern, all different.
The sparking plugs in the blank side I'd think do spark, but nothing in there to burn. No rods or pistons in that side. Just some plugs firing into a blind hole in the plate, thats how I think I'd do it. If it has a flat crank (180 degree) it'll run like a four cylinder inline, with both heads on and a full set of pistons and rods, it'll run like two four cylinder inline engines. If it has a 90 degree crank, it won't be a smooth engine no doubt, but it's the level of trying for two completely different class records with one car and one engine. Martin. |

Very unusual. Doesn't look very balanced? |

I wouldn't think it is a good idea to spark into an open cylinder, what with crankcase fumes being potentially explosive, especially if they are running on "fuel"!

Spark plugs firing into a blind hole is what I said. So no crank case fumes in the blind hole, as its a blind hole, not an open hole. You see? Martin. |
