Thanks, guys. Glad you like the details. They're why I like building engines so much; lots of details. Mike, if anything, I may be a master at hiding my mistakes. You, on the other hand are a master of ideas. I always enjoy watching how you settle for nothing less than the best possible way to solve a modeling problem. love it

I tried to get the miscellaneous engine detail parts painted tonight for some show and tell, but there's still a few colors to go. Tomorrow is "date night" and there's an IPMS show in Leavenworth Kansas on Saturday. Hopefully, I'll have another engine update over the weekend.

Alyn, I really like your injectors, they look so real!! I might copy your setup for an old Nova "Rat Packer" that I'm halfway into. It will be built as the first issue called Twister. Guess it was reissued not too long ago. I have the old first issue box.

Cool; looks like we have a few Pontiac fans around here.

I got a few more details taken care of. The starter, oil filter and fuel pump are complete. Still working on the distributor, fan belt & pulleys and the headers, but they're mostly done. Here's a couple of update pics. The short stacks and valve covers are just sitting in place. Hopefully they're be straighter on final assembly. The plan is to go with chrome valve covers, but the more I mock it up with theses stock covers, the more I like it.

With all the handling, some of the paint is already starting to rub off, some I'm gonna let the motor sit for a few days so the paint can harden up a bit more. In the meantime, the chassis and body can get some attention.

not much of an update, as I've been focused on my 57 Chevy convertible lately. The intake is pretty much done. I also scratch built the distributor. I wired the one that came with the kit, but the red wire I picked for plug wires didn't look right, so It'll get used on something else. This distributor was build by gluing some 1/2 round rod around some larger round rod. Then holes where drilled for wires, and an aluminum tube was used for the shaft. It'll look just as good as the original once the cap is painted and the wires (clear) are glued in place.

Between the scratch built fuel injection and distributor, there's almost 100 scratch built parts on the engine already, and it's not done yet.

Anyway, I thought it looked so cool that I wanted to share. The valve covers and injector stacks are not glued down, so they may look slightly askew.

The one I got was shrunken just a bit. :( Only 'bad' piece I've ever gotten from JF, though.

The progress on this may be slow. But there are times when slow and steady wins the race. That does seem to be the case here as you are still making nicely detailed progress.

final update on the motor, then I'll be moving on to body prep and chassis.

The blue valve covers are gone. This car will be a custom, so the more chrome the better. Also, for the custom look, I decided to try some clear plug wires where you can see the wire strands inside. Roth did this on his Outlaw and I'm sure many other customs have used it as well.

First off, kit fans always look way too thick, so I scratch built a replacement using .005 brass. After the blades were shaped, they were soldered to a brass shaft.

Posted Image

Here's the plug wire looms, made from .005" aluminum. Holes are .017" to allow for the .015" plug wire.

Posted Image

I don't like the way the wires lay, but since the wire is stranded rather than single conductor, it's much more difficult to add bends and curves where you want them.

Posted Image

As mentioned earlier, the distributor is scratch built by gluing 8 half round strips of styrene around a round styrene rod base. Overall, there are more than 100 scratch built bits on this motor to create the injection system and ignition.

If I come across a decal I like, or a good way to replicate a Delco-Remy tag, I may add that to the generator.

Alyn, Alyn, Alyn....you are really going out of your way to make this a killer build! You've got to do a tutorial on how to make that distributor, I'd love to see how you do it myself!

Mike's getting kind of old, so his eye sight ain't what it use to be. He keeps dropping distributors and can't find them in the green shag carpet in his work room. For Mike and guys like him. I put together a tutorial on building a distributor from scratch.

You can find it here:
