I realized today I somehow measured way off on spring width, vs. frame width? Not sure how I did it, but I did. The frame is quite a bit narrower than the spring perches on the donor axle. So I will need to make up spring mounts that situate the springs outside the frame rails after all. Not a big deal, but more work to do to get the mounts built. I wont be bolting them to the frame rails after all. With the outside mounting points it wont save me anything, so I'll build the mounts and weld them on the frame rails.
Regarding your earlier thoughts about riveted vs bolted crossmembers - the only thing I can offer is I know that Chevrolet offered a 'knee action' front end that was pretty massive (and functionally pretty lousy) in addition to the parallel leaf front end. Perhaps one was riveted while the other was bolted...or maybe is was an assembly plant difference. Glad you didn't have to deal with that at least. I also remember the frame I used for my '38 had front spring perches that set the spring center way outside of the centerline of the frame rail center, and were riveted on; and don't forget that parallel leafs don't have to be exactly parallel...
The engine is far from ready. Needs the cam and gear drive installed. Just test fitting the aluminum pan. Going to leave it there, and upside down until I get the heads and cam done.
I laid out the holes and drilled the axle today. Then I opened up the disc brake kit from Speedway to install it. That's when I realized I somehow entered the wrong numbers and got a kit for a '49-'54 Chevy car! Crap! Have to call Speedway tomorrow and arrange to exchange this kit for the correct Chevy truck disc brake kit. I hate when I do stuff like this!!!!
I'm enjoying the build. Can't post many thoughts because I know almost nothing about 39 Chevys or gassers but I am sure enjoying watching this one come together. Your other toys are cool too.
Called Speedway this morning, and as usual they were extremely helpful. Even though it's been over their 60 day limit for returns, they will take back the other kit and send out a correct kit soon. They are also swapping out the rotors for 5x4.5" pattern to match the 8.8" rearend I'm using in this build.
Axle looks great Val....Glad you decided to go that way
Thanks! I guess I can't stop myself from doing a straight axle gasser type car!
Ran into an issue trying to install the disc brake kit on the axle. I found out I"d accidentally ordered a kit for a '49-'54 Chevy car, and not a '47-'59 Chevy truck. Called Speedway, and even though it's over their 60 day limit, they are sending me the correct kit. Had to pay UPS's huge fee to ship this kit back, but otherwise it's all fixed.
I'll clean and paint the axle while I'm waiting. And go ahead with engine assembly to prepare it to drop in and mock up motor mounts.
Made a short work day of it today. I got a deal on some 4 ft. LED two tube shop lights, so spent a couple hours changing those out to give me more work light. Boy do they ever make a huge improvement! And no issues with cold weather flickering, or replacing lamps in my lifetime! Supposed to be a 40 year lifespan on the LED's.
After that I disassembled the timing cover, and removed the roller lifters. Then dropped the Howards roller camshaft in, and reassembled it. Their instructions say the roller cam needs no assembly lube, but I put it on anyway. Just seems like a good idea to me. Especially if it might not be started for quite awhile.
You know the saying that true artists make only one master piece and just mastering from there...the same with hot rods
Very nice build Val
I found out today that all SBC 350 engines are not alike! It seems when Chevy went to the later roller camshaft engines they changed numerous things. Among them are a cam plate up front to keep the cam from walking, which is great. They also changed the bolt pattern on the end of the camshaft to a smaller bolt pattern for the timing gear! And of course they eliminated the fuel pump, and installed a block off plate where it went.
So I had this gear drive timing set I thought I might use, since it was new and already here. But it wont work, so I left the double roller set in. And I'll have to go with a electric fuel pump since there's no mechanical pump on the block. I'm not an electric pump fan, but guess I'll have to go with one on this build.
Heads on, and engine painted. Can't believe my oil pump hasn't arrived? Just as well since every parts store I stopped at today told me they had no 350 SBC pan gasket sets! Can't believe they have to special order a pan gasket!!!
Will wait to do the rockers, and other pieces until after I have the motor mounts done. It will likely be in and out a couple times before it stays in.
