383 big block builds, from mild to wild, I want to hear about them!!
1967 original 383, factory 10:1 compression rated 325 hp.
Had 2 sunken burnt valves, you know the non hardened seat thing.
As purchased pictured below:
Tore the top end off, sent the heads in for hardened exhaust seats. I bought all new valves and springs for it.
Had a bad experience with the machine shop taking over 6 months to do the simple valve job. Went down there face to face and said I am taking my heads out of here.
The guy had put some work into them and wanted to finish them, he said will be done in two days. Said OK, picked them up in 2 days.
So after this long wait and delaying the project, I have done all of my heads in house from here on out on all of my builds since then.
So back to the 383, fresh heads, put on an Aluminum Passenger side exit water pump for the A Bodies, new timing chain, new points distributor.
Did not go into the short block at this time.
Fresh 516 Heads:
Cleaned up and painted the original 4 bbl intake (on the right pictured)
Final Assembly
And here it is up and running:
