My good fortune on my holidays

[figment]

I found a 6.5L for a good price it ran when it was removed from a wrecked '93 and I also found a truck that I always wanted to rebuild from the frame up and can get it cheep like feel really guilty cheep. So it'll be my toy, in other words everything I want in it.

I was wondering if anyone has gotten aftermarket cranks or rods for the 6.5 before? I'm thinking of rebuilding it and having the balanced and blue printed get rid of all the bad vibes, roller cam and roller rockers, a nitrated steel crank and rods so this thing will run and it'll put up with just about anything I do with it.

I know these engines don't put up with gobb's of power, but it would be nice to drive it and not worry about anything as long as I have it.

Some reading on here will have you worried about the 1993 block cracking more than rods or the crank. The vibration damper fails often and takes out the crank -keep an eye on it for signs of failure.
So you will find yourself looking at a redesigned $7500 Optimizer or going through surplus military engines not worried about cranks, rods etc. Just rings.
Swapping another type of engine in may get you your trouble free goal.

Missy has a thread using a aftermarket crank.

Hey War Wagon are the 92s bad for bad blocks cause I eventually want either 6.5 turbo with mechanical IP and they are only 92 and 93 right?

you can convert any year 6.5 to mechanical. year doesn't matter. i have a 99 engine in my 93, mechanical.

have you ever thought about cryoing your block? that might stop it from cracking more. i would try to get a optimizer block, steel crank, main studs, cryoed and shot peened rods, roller rockers, balanced rotating assembly. fluidampr, delta cam, and slightly lowered comp ratio maybe 20:1 and cermaic coated pistons . That i think is a engine that could hold some power.

If you dont need to buy a whole new long block the new blocks alone are available for a couple thousand. I would be satisfied starting with any recent, used AMG engine though. There are military government liquidation auctions online at bases all over the country that have 6.5s occasionally, and the details will say when the military originally bought it and from where. Then there is a good deal when Ted's trucks has inventory of these military enignes, checks compression, runs the engines briefly, so you know better what youre getting. I would have no issues running a rebuilt diesel depot engine, or a personal rebuild you know was done right. However, if you are going to spend a good amount of money on all the fixins, I think it would be best to start with the best base. The Optimiser is a good one to start from, what Ted's sells and what are auctioned along older GM engines too. You could put the forged steel crank in an Optimiser block/heads. Otherwise P400 engines come with forged steel cranks and an awesome main cap girdle (expensive enignes though)

Thanx for the info Buddy. I keep forgetting that couple of ya run these on the drag strip, I'll be saving my penny's for a bit to get a P400 then, it's a natural better quality go with better money.
