Did it have an aluminum band just above the collar that is used to clamp it in place in the engine? If so, that band would have the part number, mfg date, etc stamped on it. Very useful info.
Definately not a p***enger car application. 40 series or bigger truck or industrial application possibly.
It did not have the band on it. The engine has a factory dual quad setup and has the 3814690 Hipo heads
I read about a special ordered transistorized ignition system that was available for the 409 could this be the distributor for that setup? Said it took a special magnetic field distributor.
Can you give us the numbers off of the front of the block? Maybe someone for some reason thought it would be a good idea to put a 425hp top end on a low compression grain truck motor.
That distributor looks pretty much like a regular distributor, except the points and condenser were replaced with the transistorized pieces.
here's a picture of another one, just to give you a chuckle https://www.jalopyjournal.com/forum...ributor-made-into-an-oil-pump-primer.1139954/
I don't see any electronics on it, and there's only one wire, can we see inside the thing where the points are? another picture perhaps? The Chevy truck parts book lists one distributor for trucks from 58-64 with the 348 or 409, part number 1112767, googling that number finds nothing. The vacuum line and air filter can and internal valve are related to the governor used on the big truck engines, there's also a vacuum diaphragm on the carb.
Well, I'm going to have to say that some guy found it in a mid 60's truck and stuck it in his car and stuck the dual quad setup on it and didn't get the distributor or make any other changes. Pretty much the same as when you see an unmodified tall deck 427 in a car now days. My buddy was a big block freak for years and had at least one kid who had stuck a tall deck in his Chevy show up at his place asking why his aluminum high rise wouldn't bolt up on his engine. Kid had the car running and driving governor and all as he had put it back together when he couldn't get the intake to fit.
Could it just be a 409 truck block. I have seen lots of 348's in trucks but have never come across a 409. What are the numbers on the front tab of the block? Dip stick on the p***enger side?
neat! is there a casting date code on the back of the block somewhere? Might also be above the oil pan rail.
That is a late 64 or 65 block used in both car and truck. In trucks it may have cylinder relief cuts to reduce the compression. **G was only used as a replacement for trucks. What is the head casting number? 690's or did you really get lucky with a set of 583's used with the Z11 high lift cam Oops! I see you said 690's. Quite a find for certain. I think I have a distributor out of a 409 in the shop that needs a good home. PM me if interested.
Truck 409's are the new hi-po 409's now......maybe someone was on the cutting edge ? Sadly they use to just s**** those 409 truck motors.......
I know this thread is nearly a year old but I came across it while looking up the distributor I have. It looks to be pretty complete so I figured I would put a couple pics as the OP had requested. But . . . I don't know how to post a pic here from my laptop.
there should be a ****on below the place where you type in the text, that says "upload a file". You click that, then upload the image file (which is what we call a picture on a computer). If you have trouble, keep asking, we'll get it figured out.
here is the tutorial for posting pictures. It is super easy https://www.jalopyjournal.com/forum/threads/how-to-post-images-on-a-thread.922350/
you could even clean off the aluminum band on the distributor, and put the numbers here for us to see. Then we could look it up and know for sure that it's a medium duty truck W motor distributor
doesn't show up on the 409 site 348/409 Part numbers (348-409.com) most of the 11127** units show up on the 348 side??
the 1969 Chevy truck parts book shows 1112767 to fit All 348-409 from 58-64 (first design). So it's a truck distributor. Like I thought.
