402 TQ at 4000 RPM

Hope it sounds as good in person as on paper.

Hey, thanks a bunch. It does sound nice and actually turned out to be exactly what I wanted to build. Very streetable but has enough to get after it when I want.

Do you have a price breakdown of this rebuild? I'd be interested in seeing what it cost, including labor. Thanks!

Sounds very strong

All of the receipts came to about $1900. This was a block and heads that I found at a place in Houston called Best Core. The name is a little deceptive as there is a lot of junk. I was able to find a standard bore short block and dug through what seemed like hundreds of heads to find the 441s. Once in hand I tore everything down and took it to my machinist. He cleaned up the block and heads, bored the block, turned the crank .010 under and redid the heads. He also sent out the rods/pistons for resizing and balancing. I did all of the motor assembly and installed. This was about 5 years ago so I imagine prices will be up a little.

It also helps to have friends with a big shop and every tool imaginable.
