Slanted Goals
Some of this content parallels the content going into my valiant thread which is the car this slant six is for but this is a slant six rebuild thread. It's purpose is to get input from other members who have built slant sixes before. This is by far not the first time I have rebuilt an engine but it is the first time I do it on a slant six. In years past, you simply bought a spare six and when yours started smoking, you just swapped it out. Now a days , I am finding these leaning towers of power are getting very scarce and the ones you do find in yards anymore are there for good reason and beyond any hope..
What I have here is a 1970 slant six. Numbers matching engine to a dead 70 challenger convertible. I pulled this engine and ran it in a 72 I had for awhile and then I pulled the engine out and sold that car, so it was painted and set up to look stock in a 72 model year car.
Now I am going to install it into a 63 valiant so I am going to be repainting it red to look period correct for a 63.
when I pulled it apart, I found that it had been rebuilt before. The main and rod bearing shells have dates on them which suggest somewhere around the summer of 1993 is when this may have occurred.
I found the crank had been turned .030 under and the rods .020 under and the block has been decked (unknown how much was shaved) and it was bored .030. over and has no ridge.
I plan to run a Clifford header and intake with a 390 cfm carb.
I also plan to swap the head out to a different head that is a 1973 head that was shaved a confirmed .070 under.
The shaved head should bring the compression up quite a bit ??
ok, some more updates as this happens
