Its better to find that mistake now than at the 4 mile mark on the odometer. I read an older post from a motorhome forum. They were using caddy engines too. Ine guy did the same thing. Lifters popped out when the rockers failed. Very costly mistake on his part. My heart sank when i read it. Stay encouraged. Your doing it right. I remeber Mad Cadder telling me" it costs what it costs and its cheaper to do it right the first time" Thats why i choose to go with the 15 cam ect. Your ride is very nice and your attention to detail shows. Thank you for sharing. I enjoy reading everyones posts on there project. It keeps me encouraged too. We got alot of great folks here.
