Re: Rebuild time on the 230 flat head engine
For everyone's comedic pleasure, I have posted a pic of one of the six wire (most likely an original) that was hacked up and spliced to utilize regular spark plugs vs. the new wires and correct plugs. It actually ran with the hack job wires. Pics of new vs. old distributor caps also.

Re: Rebuild time on the 230 flat head engine
Some additional work completed on the engine today.
Paint head gasket/head installed
oil dip stick, oil filler, front pulley, installed.
I was given 3 spring metal pieces that snap into the drain-back holes in the block that are located adjacent the valves. Anyone have comment on these?

Re: Rebuild time on the 230 flat head engine
Even with the extreme heat, I get a little more completed each day. Today was only 104*F, last few days were 112-114*F.
Almost ready to drop into the M37.

Re: Rebuild time on the 230 flat head engine
looking good ! are you going to port match that intake before buttoning it up ? mine was miles off, I also massaged the radius to each runner under the carb base as it was very sharp. all work was left ruff to aid in the atomization of carters coarse droplets.

Re: Rebuild time on the 230 flat head engine
Great thought. I will get out the Dremel today and go to work. Break some of those sharp edges into nice radii.RMS wrote:looking good ! are you going to port match that intake before buttoning it up ? mine was miles off, I also massaged the radius to each runner under the carb base as it was very sharp. all work was left ruff to aid in the atomization of carters coarse droplets.

Re: Rebuild time on the 230 flat head engine
RMS, thanks for the comment. I did some work with the grinding stones and Dremel today. Not NHRA quality, lol. but should help the flow somewhat. If anyone is interested, I have one of these available. I think this is an older style intake due to the limited tapped ports. Part number is highlighted in silver Sharpie.

Re: Rebuild time on the 230 flat head engine
Researching the letters and numbers for the T245 block. Still looking for a good website that has all info, ( alpha as well as numeric) for these engines.
pic with "62" is below the distributor, other is the back of the block.

Re: Rebuild time on the 230 flat head engine
Many moons ago, An old salt mechanic showed me how to take two gaskets and a piece of window screen to make a sandwich, then put it under the carb to further atomize things. The mileage went up a bit, no notice of power loss. Smoother takeoff under WOT, too.
Funny what tricks work with these simple old engines.

Re: Rebuild time on the 230 flat head engine
WOW, I forgot all about that trick. I do have a piece of titanium screen that I may try this with. I read about it in an old car magazine, maybe a Car Craft or Hot Rod. Dug around in the shed..................found it. I was going to use it on one of my Carter Thermoquad V8's. Never did, glad I never tossed it out.PoW wrote:Many moons ago, An old salt mechanic showed me how to take two gaskets and a piece of window screen to make a sandwich, then put it under the carb to further atomize things.

Re: Rebuild time on the 230 flat head engine
Here is my home made titanium screen gasket below the carb.
We shall see how she does.

Re: Rebuild time on the 230 flat head engine
its been a while but AI think the clips that go in drain back holes are to restrict the oil from drainging valve lifter area too fast. ??
