The night the Hemi went down....

....and stopped working.

At low rpm on highway, slowing down for a residential area, the truck started 'shuddering' kinda. (It had done this once before, and it was injector #3).

It was hard to keep running. It died and coasted off the side of the road.

Hit the key, it cranked, made some aweful (metally) noise and stuck.

Stranded. The temp outside was 17F and dropping. Just days before Christmas.

#6 intake valve spring.

And so my adventure into the world of Hemi's began.

I can say easily, these are very well designed motors, and I actually had fun.

Im normally a small block chevy guy, but there was something about these motors that were very intriguing. As well as simplistic.

So ordered a new one from Alameda Motors. It has some new 'updated pistons' and some other 'improvements' they said. So that sounded good.

The pistons have a black anodized skirt I think and a black arrow on the piston face (pointing forward).

The new motor arrived, and the reluctor ring was a bit dinged up. I didnt want to take a chance on it, so they sent a new one. And I slapped it in.

That's tough to look at. Often when the the spring breaks it won't actually drop the valve. But when the valve does drop it it usually beats up the head and smashes the piston or in your case goes through the side. Has anyone sleeved a g3 hemi?

Never have seen a dropped valve look so bad.

The new engine should run better. Good luck and keep us posted.

My engine is sleeved in hole number 2 so since the wall now has two diff metals in it I have to tune the motor to that cylinder as it's the hottest running hole in the engine.

That's good to know that they can be sleeved. I had a 324 Olds that was sleeved in all eight holes. It had .125 over pistons. Back then I thought that was the standard way it was done, make'm as big as possible.
