I decided to try and tackle the job myself instead of having Gary do it all for me. I did need help and have many questions for him while doing the job.. Most of the time, the answer was DUMBAZZ figure it out.. haha.. Big thanks to him for helping me out.. Sooo.. After installing twins, almost immediately blowing the head gasket, and then installing a new head, the rear main seal took a dump.. haha.. I took the truck to Cope Customs for the rear main seal install.. Bobby pulled the trans to find the flex plate was cracked in 9 places.. This was a "heavy duty" reinforced flex plate.. haha.. So now it's getting a new one, again.. It's nice to have friends.. Gary and Bobby both have helped me out a lot lately and I really appreciate it. Their shops are Southern Diesel in Lakeland, and Cope Customs in Bradenton. If someone needs an install or a fix, they're both up for the job.. With their help, I believe I may make it to the dyno day.. :Cheer:
