Another 2x4/Batwing/small block about ready to hit the streets again.
No, it's not in a 56-57, but the entire drive line is all early Chevy.
I still have a few minor things to do, but it won't be long before I fire up the 389 after sitting on the lift with a broken piston for 6-7yrs.
Everything is tight, but it has all gone together better than I expected. The only real modification I had to do was the oil filler tube to get it to clear the old York style air cond compressor. I was surprised that with the Backwing turned around backward, there was plenty of clearance for the distributor and coil.
If it runs as strong as it did before I broke a piston, I'll be thrilled!
Would you post a pic of the outside of the car that the engine went in?
It's a 350 block (ACTUALLY, it's a large jorunal 327 block) bored .060in over, stroked to 3.75. According to Speed Pro's piston chart, a 383 that is .060 over is a 389.
After the small journal blocks with the hole in the rear for crankcase ventilation went away, Chev continued to make some Service replacement blocks that had large journals, oil filter pad machined for a spin-on filter and a hole in the rear of the block. This kind of block could be used for retro fitting 67-earlier cars with a new engine that would use all 67-earler parts such as solid, NO-NOLE valve covers and have either a road draft tube or PCV plumbed into the rear hole. These blocks are kind of hard to locate today, but for building a factory appearing 283-327 with 350-389 cubes, it is just the ticket!
This is the same engine, BEFORE I broke a piston, with an early Z28 intake and Q-jet. Since I had to tear it down to replace all pistons/rings, I decided that after 30+yrs on the shelf, I'd put the 2x4 setup back on and add a Batwing.
The old 350 with 300+Kmi and the new 389.
The grill has 1954 teeth in it and years ago, some teeth got broken (people backing into it in the big parking lot at work). Several months ago I stumbled across some misc parts a guy was cleaning out and in his stuff he had a complete set of good driver teeth.
This is the service replacement large journal block with hole in the back for crankcase ventilation.
And this is how I plumbed a PCV setup on it with the Z28 intake.
