    What bore size did you end up with on it? That is really the limitation. From there you can figure CFM Demand on the engine and know how much airflow you need to feed it. May not need as much air as what you may think. Look at the Stockers and Super Stock for example.

    Some of the earliest PCV systems that had the valve on rear of intake used that baffle cannister, but it was there and used with road draft tube from '55 on up until the PCV valves came out.
    Later, mid '60s, block was changed and that hole was eliminated. In post #238 is an early block with the earliest PCV adapter in the hole where a road draft tube was fitted in earlier years. Some of the other pics you can see the hole with nothing in it

    Finally ponied up and spent some money on some lifters. Crane Cams has always been really good to me with all the Early Hemi stuff I do so I found a Pro Series lifter they offer that will work perfectly with what I'm after. These are .904 "Mopar" diameter lifters with centered pushrod cups. With a larger diameter lifter they typically will have a larger roller wheel that will handle more spring pressure and last longer. I know these are excellent lifters as we have run them far past their recommendations with great success. Like to thank Robert for a great deal on these lifters for my own personal build - Thanks man!

    Next step will be to finish machining the bronze lifter bushings with a oil slot and drill a smaller hole to feed each lifter. This essentially makes the oiling system to full time oiling the way I'm doing it with the band around the bushing. I have to be careful that it doesn't line up with the hole that feeds the pushrod hole directly.

    You have to be one of the more advanced builders we have on the HAMB at this time. It's like getting a free graduate course in engine building just keeping up with your threads.
     
  9. You are one of the finest craftsman that I have ever seen. I really enjoy your posts.

    Interesting evening, I stumbled across a picture on Instagram that I thought may possibly be my friends Dragster (Herb Shelton) that was in their family. I've been trying to get pics for about 6 months and they have not been able to locate any. My gut feeling said this was it! Low and behold his family confirmed this is the dragster a few minutes ago! So the cool part is the Hilborn that was given to me was once used for this car on another motor. Now I have traction to find more info and pictures!

    Pretty good! I actually like the looks of the dragster, may recreate it.

    I've been buried with work and just not in the mood to tackle the mountain of work I have ahead of myself in my shop. Tonight I took some time for myself and machined these bronze lifter bushings on my mill.
    20190208_222715.jpg
    Nice to have a rotary table, comes in handy! Also used a lifter bushing driver and used my stop on the backside to make setups quick and repeatable. Here I'm using a 3/8" ball endmill to machine a groove about .300 long. This passage is to offset the band a little for the lobe lift I plan to run.
    20190208_222910.jpg
    Here I'm drilling a #58 hole which is around .040 in size. Seems small but in reality under pressure the stream is rather large.
    20190208_223948.jpg
    First few turning out as I hoped.
    20190208_232012.jpg
    Batch of bushings are fully machined and ready for installation.
    20190208_232058.jpg
    I plan to clock the bushing like in the picture. I don't want my orifice to line up with the pushrod feed hole, that would be a bad thing. Offset enough to help feed the thrust side for each bank.

  16. Wow......I'm blown away. I thought I was cool with my 301 sbc project with untouched TRW 11/1, 4" forgings that are ultra heavy, a set of small journal Oliver steel rods and a 1966 block/crank and an old pair of 186 heads. Chuck {WAM} usually does my machine work but I haven't seen him in 5-6 years...heard his health isn't so good.
    When I collected these parts they were state of the art...now it's antique stuff.

    Did you have/or still do have, an E-Bay, "Smithberg Racing Store? Seems to me I bought some stuff quite a few years back, and now it does't come up (???) with a search. This is probably going to be the most costly "283" of all time when you're finally done with it, and everyone here stays glued to your thread and the additions. I am Butch/56sedandelivery.

    I still have it. Selling some things to clean off the shelves again. Hadn't sold anything on Ebay for many years until the past year or two.

    Last I heard Willard had cancer, think he beat it. He's back to working in his shop. I got tired of dealing with the local shops so decided to get the equipment and do my own work.

    I acquired some mid 90's Comp Eliminator crankshafts. One is a Callies and the other is a Lunati which appears to be a modified LJ 327 GM Crankshaft. Both of these are 3.160 stroke, 350 main size, and SJ Rod size. I've been rethinking my combination as of right now but I potentially may take some stroke out of one, turn the mains down to a 283 main, and convert to a Honda Rod pin. I have time to sort it out yet and a Plan B......

    I also decided on a Melling Billet Oil Pump that has the Shark Tooth Technology (basically a helical gear vs a spur gear) so it is supposed to be far smoother running. This is also far lighter as well.

    Also ended up with a full sump Kevko pan that has a nice big kickout. The pump clears this pan, close fit that may require some further modification.

    Nick, don’t take this in the wrong way but isn’t that pan a bit deep for a Jr. Fuel FED? I have been following your thread, you are clearly a master craftsman who strives for perfection.

    Kind of jumped on late- are you looking to compete in comp/ heritage series or is this empirical/ exhibition type stuff?

    It is 8"deep, not 100% sold on this particular pan just yet. If it doesn't work out here I have another engine I will use it on. We share the same concern. The other option is a Milodon 31145 that is 7-5/8" in the rear and 6" in the front. Either way I want a kickout so both will still have to be modified.

    I'm not looking to compete in any series just blowing off some steam when I have some free time.
