The following persons and companies helped me with information and further tech data that was in-turn used in my recently released book. I owe them big time for the help provided, I would have never finished the book in the short timeframe without these guys help along the way. I made quite a few new friends throughout the manuals writing timeframe also.

Motorbooks - I have to thank my editor Chris Endres for allowing me the opportunity to work with them on my 1st book and for keeping me on to do a few more! CE wrote one of the first LS1/LS6 books and just finished another book "The Art of the Cutaway Car" along with Dave Kimble (the amazing cutaway car artist), if you want further reading, his books are on Amazon.com.

Wiseco - Huge thanks to Brian Nutter and Wiseco crew for gathering piston data, specs, illustrations, piston images and the almost full-day tour at Wiseco. Impressive facility. Also thanks for showing me the town, lunch and evening entertainment.

Diamond - Thanks to Eric S. at Diamond. I had pistons covered other than specific Diamond features, but we discussed other areas of engines and he helped word a few things better.

Race Engine Development - Many thanks go to Steve D. at RED for the impressive block machining techniques, sleeving images, step-by-step text procedures, common issues and other information.

Kurt Urban - Thanks for taking time out of your day to answer a few questions! Wealth of knowledge.

Compstar - Thanks to Nick N. at Compstar for the tour of Callies/Compstar, the crank and rod images, and for answering any question I could think of! Impressed by meticulous product control procedures.

Harland Sharp - Thanks to the Becker family that owns and runs H.S. I was able to get the nickle tour. From start to finish H.S. machines and assembles rockers in-house starting with extruded aluminum bars. Randy Jr. and Mike showed me the facility, and the behind-the-scenes operation of H.S. Neat setup, was amazed by how much machining and assembly is done in-house.

TFS/TEA - Thanks to Brian Tooley for taking time out of his day to meet with me and talk heads/cam and power adder influences. I wish I would have been able to tour TFS and Summit, but maybe another day - I did drive by Summit, pretty huge facility.

PRC/TSP - Thanks to Jason and Trevor for allowing me to photograph images in their shop of a few different cylinder heads and borrowing a plethora of engine parts to photograph. Without these guys half of my images would have been a lot harder to obtain.

Sunset RaceCraft - Thanks to Tracy Dennis of Sunset RaceCraft for the machining procedures, info, and opening up his shop for pictures of the varying machining operations.

gator's 99T/A - I used both John's 404ci LQ9, and his dad's 454ci LSX for buildup photo's throughout the manual. I appreciate the permission fellas!

I think that about covers it!
