I am looking for a 400 block and crank for a very mild build. I gave a 76 400 block and crank years ago to a fellow member. Of course now 10 years later I need one. I want to take the street car and make it mild. Looking to go on 500+ mile trips with it. Right now it is running 11.8's at 3900lbs.. Not really a long distance cruiser.
Have a lot of people trying to talk me into an LS but would like to keep a Pontiac in it.
I am in south NJ.

I have a standard bore ‘73 400 (988) that was magged and hot tanked. I since picked up a “71 455 so the 400 sits on a stand stored in my enclosed trailer waiting for a project. Obviously disassembled but have crank etc. PM me with any questions if you’re interested.

I have a '557 block that was freshly hot-tanked and bored (forgot size) just before I got it. Comes with crank and flexplate. It's just collecting dust in my garage. Would take $200 for block/crank/flexplate just to make more space in garage. Located just south of Baltimore near BWI airport. PM me if interested.
