thanks, I thought maybe due to its squareness the engine might lean to one more. But thanks for letting me know

What about parts that work. Like I heard BBC pistons and sbf 302 rockers will work? Is this true, if so what other internal could be used in the 425.

What hei, exsaust manifolds, intake and cam, are used a lot.

I guessing I should look for a 750 or 800 qJet

So are you going power adder or stock? You've mentioned both ways, I'm confused.

RocketRonnie

well as much power I can add on a stock block. Just researching at this point

I renamed the thread for the sake of not having so many threads open. I will direct all my question on this one. Hopefully together with your experience and my muscle I can get this 425 running and ready to go in my 63 Lesabre wagon(pictured).

so i acquired this engine specifically for the wagon. Engine has B heads, said to be from 1966. In rebuilt condition, supposedly. No carb or much accessories.

it came with a th400 from the same year.

i put it on the stand and pulled the valve covers on was dry and the other had some oil pooled in the corner. Next i will pull the intake to look at the valley, then the pan and rotate it.
pictures to come

Make sure of the year and what that motor came out of. 425s, for the three years they were made, had different cam bank angles and lifter bore combinations.
