Hey Guys,

I'm new to the whole forum thing. I have question about replacing my LMM with a new long block or rebuilding.

Does anyone know of a good mechanic in the phoenix area? I took it to a local shop and they want to install a new GM long block. To be honest I don't have the 14K they want to fix it right now.

Any suggestions on buying a GM long block or remanufactured block?

Thanks in advance from a newbie!

I was driving down the freeway and it started missing. I pulled off the next off ramp and then it last power and banging loudly.

I towed it to a shop here in town. the tech tried starting it and they said something internally was wrong, but did not tear into it. just said to purchase a long block and install it.

It sounds like metal to metal when starting it.

Copperhead Diesel out in Mesa is your best bet. Sean deals mainly in dmax stuff and is very fair on pricing. Tell him James that owns the Limo dmax sent you, he will take care of you

You guys do realize the o/p sounds like he's looking for stock shortblock, right?

O/P, you can rebuild what you have for under $5K, depending on how much needs to be done. It sounds like you broke the crank, though.

That's why I sent him to Sean. He can do a full stock motor fix up or go all out should the op choose

This is why I should probably check the forums more often lol. Spoke with OP a few days ago, I'm not sure it's an issue requiring replacement of the engine but we'll have to see it in person to determine that for sure.

To OP, if you do need an engine or feel like undergoing it yourself, I would avoid Jasper engines and would stick with either a GM long block or find a junkyard take-out around town with low miles if you're trying to save some money. Let me know if there's anything we can do to help, lots of good info on this forum too.

Just an update on the motor.

We decided to go with a Mild built motor with EFI live, PPE race valve, lift pump, DPF and EGR delete.

While its getting the motor done a Cognito 10-12 lift and 37 toyos.

I'll get pictures up when it's all completed. I don't see many RCLB with this combo.

Sean at Copperhead.

I want to thank James for the recommendation and Sean for patiently waiting while I decided what to do and save up the money for it.

Can't wait to get it back.

The motor is in and the lift completed.

Just have to finish a few things and it will be back on the road.

Want to give a big thanks to Copperhead Diesel Performance for all the great work they did on the truck and G&M Motorsports for installing the lift.

Here are a few pics of the truck.
