Duramax conversion results thread

[guruerror]

I'm going back and forth between whether I should build a 408 stroker or go with a Duramax conversion. I'm not looking to make any move until I reach a 'critical' rebuild point...I just cracked 80,000 on my 05, so I'm good for now; but I thought it would be helpful for us Duramax-prospects to have a thread highlighting the success/failure stories of past conversions.

The main points I'd like to know are:

• Was it successful?
• Where did you get the conversion done?
• How long did the conversion take?
• What was the total cost?
• Are you happy with the conversion?
• What do you see as the biggest post-conversion advantage?
• What do you see as the biggest post-conversion dis-advantage?
• Any other feedback...

Thanks in advance.

I'm curious to see if you get any response to this.

I'd say go with a 427 stroker and you will need a better trans anyway so 20k vs 30k and no electrical problems from the conversion. 30k buys a lot of gas

0r just a built LS1. There are plenty that make 600hp with cam and heads now
you could probably do that for 13k with 5k going towards a built trans

Until someone come out with a plug and play harness for the diesel conversion it sounds like they are huge problems

I think this truck screams for a diesel. With the weight of it, the low end would be great, and I could run waste oil filling up at Chik-fi-la when I stop to eat.

Stroker kit and 4.88's..Had a chance to drive a Hummer with this combo, you'll love this setup! Now I'm saving my pennies

So its been 8 months on this thread.

Did you do a conversion? What did you go with?

I'm sitting at 150k on my 03 H2 and starting to look at options. I'm almost definately going with a duramax conversion. It would be a stretch for me to consider a stroker as previously mentioned. Just not practical for what I use my truck for.
I spend almost every weekend on the trails and the rest of the week its a daily driver. Diesel seems the best option.
