I have a 69 and a 70 383 and a 78 440 that is stuck. Also have a 400 in my 81 big horn dually and a 440 in my motor home car hauler.
I have every thing to rebuild the 69 383 with 10 to 1 pistons, forged crank, 440 cam and fresh 452 heads.
I would want to put an aluminum intake and water pump and housing on it to lighten it up a little.
