Glad I found this site. Lots more swap information than anywhere else. I also joined as a paying member and bought the Duramax Diesel Conversion book. I'm glad it was for a 1989 FSC since it should be similar to my 1990 454SS.

I've had the 454SS since I was 18. It has seen several different BBCs but has been in storage stripped to nothing for 3 years. My wife rolled her 2006 ECSB LBZ last week (wife is fine, truck's sheet metal is not). So I'm way ahead of the game with a complete donor truck and a ready-to-accept transplant truck.

I'm anxiously waiting on the book to arrive in the mail, but I don't have the time to start the project until July.

I'm not a duramax newbie. I daily drove my 2004 LB7 truck at 850 rwhp for a while. It is currently being finished again, this time shooting for over 1200 rwhp on diesel only. Now I daily drive my 2004 LLY dually that laid down 500 rwhp and 1000 ft lbs with only turbo, exhaust, intake, transmission and programming.
