- 351c 2v, FMX Transmission. Ordered from Sanderson Ford in Phoenix, 99k original miles.
Restoration shop was able to tear down my 351 this weekend so figured I would update those that were interested! Tranny is also all cleaned up and rebuilt. I’ve included all the pictures I was sent, as well as the texts I received from the shop. Nothing I didn’t expect to be honest. Could be better news but I guess there’s always worse, at least that’s what I’m sticking with! You can see the pushrod on 8 that I was fighting to get out, as well as the missing one from 5.
Hi Peter,
So, I will send you pictures of your engine during tear down. Clearly, this engine was rebuilt not long ago, or at least doesn’t have many miles on it.
The problem is, the rebuild was very poor, it looks like they just honed the cylinders, also they didn’t properly line up the piston rings. There are cylinders with heavy scrapes or scratches, which take time to get. Also there is something in one of the cylinders, that clearly shows something damaged it.
So, it .030 over now, hopefully we can clean up at .040. The crank is .30 rods and .30 mains. Honestly I don’t like to go more then that, but we will see, we maybe able to just polish the crank, not sure tell it’s verified.
Clearly the valves are not in good shape, possibly just a poor rebuild job, nothing hit them, just think poor rebuild.
The cam, well it’s a stock cam, nothing performance. Why the push rods are bent would indicate over revving, or they are too long, which I doubt. Honestly I feel that, who built it, just didn’t understand what they needed to do, or how to do it.
Didn’t see any issues with the rockers. However when everything thing is cleaned up, I will possibly see more.
Over all it’s a great engine to build.
Also the transmission is done, it was in bad shape, had a lot of rust inside the pump.
